Remix Vs Next.js – Which One To Choose?

There are lots of frameworks built on top of React. Some of them are Next.js, Remix, Gatsby, Redwood, Blitz etc. Next.js has gained a lot of popularity because of the performance, developer experience and tight integration with deployment platforms that it offers. However recently, Remix has been heavily discussed and compared to Next.js as an alternative. Lots of programmers are using Next.js as a potential tool to build apps. Remix is being presented as another option, but developers need to know the comparison and why they would want to pick one over other. Hence here we came with a comparison of Remix vs Next.js. Let’s compare Remix and Next.js on the basis of various parameters. 

Remix Vs Next.js-

1. Web Standard APIs Vs Node.js APIs-

Remix is built on top of standard Web APIs, whereas Next.js is built on Node APIs. With Remix you won’t have to learn as many extra abstractions over the web platform. You just need to learn useful concepts no matter what tool you decide to use later. Also, APIs, the core of Remix doesn’t rely on Node dependencies. As Remix doesn’t depend on Node, it is more portable to non-Node environments like Cloudflare Workers and Deno Deploy.

This will let you to run Remix on the edge easily. Running on the edge means server hosting your apps are distributed around world rather than being centralized in a single physical location. Whenever a user visits website, they are routed to the data center closest to them for fast response times. 

2. The Router-

Route is one of the most important parts of application because we are building a web application. In Next.js, they have their own router using the file system, hence you can create a pages folder and put files there,

pages/
  index.js
  about.js
  Contact.js

These files are going to becomes pages inside the application, with below URLs.

- / (this is index)
- /about
- /contact

They also have useRouter hook to access data from router like search (query) params or methods such as reload or push to navigate to another URL.

In Remix, they use React Router v6 internally but they provide a file system based system, rather than pages Remix call them routes, but the general is similar.

routes/
  index.js
  about.js
  Contact.js

Those files are going to become routes with same URLs as in Next. Main difference comes with the introduction of Layout Routes.

3. Layout Routes-

Most common requirement of user interfaces is to re-use a layout between two URLs, a common example is to keep header and footer on every page, however this can become more complicated. Amazing example of this is Discord, let’s analyze-

You can see four main areas-

• Left column with list of servers
• Next column with list of channels
• Widest column with list of messages
• Right column with list of users of server
• It’s not image but not you can have list of messages for thread replacing users

Whenever you want to build this UI in Next.js, you need to create a file at pages/[serverId]/[channelId].tsx, get the data os each list and render a component like- 

function Screen() {
  return (
    <Layout>
      <Servers />
      <Channels />
      <Messages />
      <Users />
    </Layout>
  )
}

When the user navigate to another server or channel, according to the data loading strategy you used, you may need to get load everything again with the new channel or server. This is because Next doesn’t have support for layout routes, hence each page renders everything on the screens, including shared layouts between screens. 

As opposed to Next.js, Remix has support for that, so in Remix we would make a file structure like this:

routes/
  __layout.tsx
  __layout/
    $serverId.tsx
    $serverId/
      index.tsx
      $channelId.tsx
      $channelId/
        index.tsx
        $thread.tsx

While you have more documents, this will assist you with keeping the code more coordinated and to make stacking information more improved.

Vite JS – All You Need To Know

If you are looking to improve your experience in frontend development, Vite JS is for you. It is the next generation of frontend tooling. Vite JS consist of a dev server that bundles your code for production. It allows programmers to set up a development environment for frameworks such as Vue and React and even for Vanilla Javascript app with dev server. Apart from this, it allows the development team to hot reload in just three commands. 

Vite offers a fast and opinionated build tool with highly customizable API using plugins. Also it supports many popular front-end libraries such as Preact, Vue JS, React and Vanilla Javascript through templates. Let’s see details of Vite JS.

What Is Vite JS?

Vite is a build tool that aims to provide faster and leaner development experience for web projects. It achieves this in two parts- First, in development, app code is not bundled, instead code is imported into browser using ES Modules, the native module system for Javascript. As ESM is supported in all modern browsers, Vite can take an advantage of this to completely remove a build step while in development. Libraries that need to be imported are still compiled, but for this Vite makes use of esbuilt tool written in Go. Esbuilt pre-bundles dependencies 10-100x faster than JavaScript-based bundlers.

Second, Vite provides a build step using Rollup that has been highly optimized for generating static assets. Taking advantage of Rollup, Vite also provides a diverse plugin ecosystem. Standard Rollup plugins can be used with Vite, and custom Vie-specific plugins. Vite plugins extends Rollup’s well-designed plugin interface with some extra vite-specific options. Thus, you can write a Vite plugin once and have it work for both dev and build.

Latest version of Vite.js offers lots of new features. Released on 16th February 2021, Vite 2.0 offers completely redesigned architecture, first-class CSS support, a new plugin system and so on.

How Does Vite JS Work?

Browser support for ES6 modules was poor when ES modules were originally introduced in ES2016. Thus, lots of current browsers now support ES modules natively, and allows you to use import and export statements natively. You can include imports in HTML by specifying that you’re importing a module using type+”module” attribute in script tag: 

<script type="module" src="filename.js"> </script>

According to the documentation of Vite JS, ES import syntax is served directly to browser in source code. <script module> native supported browser parses them automatically, making HTTP requests for every import. Dev server receives HTTP requests from browser and executes any necessary code changes. This improves the speed and makes Vite server very rapid.

Performance-

Vite dev server starts instantly, and with the Hot Module replacement, eahc code is reflected in browser quickly, sometimes instantly.

vite v2.1.3 dev server running at:
> Network: http://192.168.1.90.3000/
> Local: http://localhost:3000/

ready in 467ms.

Features Of Vite JS 2.0-

1. Great CSS Support-

Vite 2.0 offers features such as CSS splitting, URL re-bashing and so on. These features are supported without configuration. Resolver of Vite improves @import and url() paths in CSS by respecting aliases and npm dependencies.

2. Faster Builds-

Latest version Vite 2.0 offers faster build time with ESbuild. ESBuild is a bundler written in Go. It is 10-100 times faster than bundler. Vite 2.0 takes an advantage of ESbuild to convert CommonJS modules to ESM for dependencies. According to the official document, Vite 2.0 uses ESBuild rather than Rollup. It improves the performance in build time. 

At the moment, ESBuild is used for pre bundling dependencies.

3. New Plugin System-

Vite improves the developer’s performance by identifying build type and accessing configs and dev server configurations. It is compatible with lots of Rollup.js plugins. New plugin system makes use of unique Hot Module Reload handling and offers API to add middleware to dev server. Plugin server is WMR based system. New system adds Vite-specific functionality to the Rollup plugin system. 

4. Framework-agnostic-

Vite 2.0 has high-quality boilerplate for various frameworks like Vue.js, Preact, React and so on. It offers a vanilla Javascript boilerplate. Other boilerplates also support Typescript. Vite offers a consistent tooling experience across frameworks because of its framework-agnostic nature.

5. Support For SSR-

Vite supports SSR for React.js and Vue 3. It provides APIs and constructs for loading and updating ESM-based source code effectively. It externalizes CommonJS-compatible dependencies. Vite SSR is an extremely low-level functionality, and the team aims to offer tooling for a more higher-level feature in coming days. In production build, SSR can be decoupled from Vite. With same setup, it can support pre-rendering.

Advantages Of Vite js-

1. Bare Module Resolving-

Yet, browser don’t support bare module imports where you can import from a package name like import { createApp } from ‘vue’, because it’s not a relative path to our node_modules. Vite searches for bare import specifiers in your Javascript files. Once it finds them, it rewrites them and uses module resolution to locate relevant files from your project dependencies.It resolves them as legitimate module specifiers.

2. Hot Module Replacement-

It is an amazing feature in Javascript bundlers that changes source code in browser without refreshing the browser. Using Vite js tool, there’s no need to reload the browser to update content, as each change is reflected in browser with immediate effect. Hot module replacement is decoupled from all modules. This makes your project faster, regardless of app size.

3. Configuration-

If you want complete control of your project, you can extend the default configuration with vite.config.js or vite.config.ts file in existing project or directory from base root directory.

Also you can mention config file through vite -config my-config.js. You can add support for custom file transforms by adding Rollup plugin to build and Koa middleware in configuration file. 

4. On Demand Compilation-

We know that, browsers send source files to compile and only required or modified code is compiled on screen. In Vite, without modified files return a 304 error code. Unlike other existing bundlers, they compile every located file in project and bundle them before making any changes. Hence Vite is great for large-size projects.

Some Other Features-

• Offers support for mode options and environment variables
• Support for TypeScript, using ESBuild for transpilation
• Asset URL handling
• Vite supports .tsx and .jsx files ESBuild for transpilation

Why Use Vite?-

1. Server Side Rendering-

Vite.js for SSR is not included or available as a template. Official document includes all the details of how to use it. It’s important to note that it is labeled as experimental. This capability is provided through a plugin.   

2. Static Site Generator-

Most Common Mistakes To Avoid In Node.js Development

Node.js has given cutting-edge web applications with two way, real-time connections where both server and client could communicate with each other. Regardless of how difficult Node.js makes writing safe code, and how easy it makes writing highly concurrent code, the platform has been around for quite a while and has been used to build number of robust and sophisticated web services. These web services scale well and have proven their stability through their stability through their endurance of time on the internet.

But just like any other platform, Node.js is vulnerable to developer issues. Some of these mistake lowers the performance, while others make Node.js appear straight out unusable for what you are trying to achieve. Here we’ll discuss most common mistakes that Node.js developers make, and how it can be avoided.

Know the features of latest version Node.js 17 at- What’s New In Node.js 17?

Most Common Mistakes To Avoid In Node.js Development-

1. Event Loop Blocking-

Being a single-threaded environment, no two parts of apps can run in parallel. Simply, since Node.js runs on single-thread, anything that blocks event look, blocks everything. Concurrency is achieved by handling input-output operations asynchronously. For instance, What allows Node.js to focus on other parts of app is a request to database engine, from Node.js to fetch some documents. 

// Trying to fetch an user object from the database. Node.js is free to run other parts of the code from the moment this function is invoked..
db.User.get(userId, function(err, user) {
	// .. until the moment the user object has been retrieved here
})

But a part of CPU-bound code in Node.js instance with thousands of clients connected is all it takes to block the event loop, that makes all the clients wait. CPU- bound codes include attempting to sort a large array, running a long loop, and so on. For instance:

function sortUsersByAge(users) {
	users.sort(function(a, b) {
		return a.age < b.age ? -1 : 1
	})
}

Calling this “SortUsersByAge” function may be fine if run on a small “users” array, but with a large array, it will have a horrible impact on performance. If this must be done and you’re certain that there will be nothing waiting on the event loop(for instance, if this was part of command line tool that you’re building with Node.js and it wouldn’t matter if entire thing ran synchronously), then this may not be an issue.

But in Node.js server instance trying to serve thousands of users simultaneously, such a pattern can prove fatal. 

If users array was retrieved from the database, the best solution will be- to fetch it already sorted directly from the database. If event loop blocked by loop written to compute the financial transaction data, it could be deferred to some external worker/queue setup to avoid hogging the event loop.

There’s no perfect solution for this type of Node.js problem, instead every case needs to be addressed individually. Main idea is to not do CPU intensive work within front-facing Node.js instances- the ones client connect to concurrently. 

2. Deeply Nesting Callbacks-

Generally, nested callbacks referred to as “callback hell”, is not a Node.js issue in itself. But this can cause problems making code quickly spin out of control:

function handleLogin(..., done) {
	db.User.get(..., function(..., user) {
		if(!user) {
			return done(null, ‘failed to log in’)
		}
		utils.verifyPassword(..., function(..., okay) {
			if(okay) {
				return done(null, ‘failed to log in’)
			}
			session.login(..., function() {
				done(null, ‘logged in’)
			})
		})
	})
}

In this way, by nesting callbacks, you can easily end up with error-prone, hard to read and also maintain code.

One solution is to declare these task as small functions and then link them. Though the clean solution is to use utility Node.js package that manages asynchronous Javascript patterns like Aync.js:

function handleLogin(done) {
	async.waterfall([
		function(done) {
			db.User.get(..., done)
		},
		function(user, done) {
			if(!user) {
			return done(null, ‘failed to log in’)
			}
			utils.verifyPassword(..., function(..., okay) {
				done(null, user, okay)
			})
		},
		function(user, okay, done) {
			if(okay) {
				return done(null, ‘failed to log in’)
			}
			session.login(..., function() {
				done(null, ‘logged in’)
			})
		}
	], function() {
		// ...
	})
}

Just like “async.waterfall”, there are lost of functions that Async.js provides manage with different asynchronous patterns. 

3. Invoking Callbacks, Multiple Times-

Javascript is popular because of relying on callbacks. Callbacks were the only way asynchronous elements of your code communicated with each other in Node.js until promises came into picture. Still package developers  design their APIs around callbacks and hence callbacks are in use. Mistake that developers make while using callbacks is calling them multiple times.

Software Outsourcing Trends To Follow In 2022

Outsourcing is a hot trend in software development, however its adoption needs organizations to rethink about their business processes and introduce technological innovations to remain agile. To keep you on track with the IT outsourcing market, we’ve collected some trends for 2022. Let’s see which are those.

Software Outsourcing Trends To Follow In 2022

1. Digital Enablers–

Since the pandemic, it has been noticed that we’re moving in the direction of digitization very rapidly. All this started as a forced work-from-home, new strategy of hiring, communicating and collaborating without borders. At the same time, remote work standards contribute to the development of new ways of solving business challenges. 

What are digital enablers and why do they matter for businesses in 2022?

In general, Digital enablers are tools and technologies that help to achieve process standardization and automation. Some of its examples are- Agile working processes, enterprise resource planning(ERP) system, Project management software, Team communication channels and platforms. 

These digital enablers contributes to enterprises hugely switching to cloud based solutions and robotic process automation (RPA). Gartner describes “distributed enterprise” as one of the strategic technology trends for 2022. 

As per Gartner, involving geographically dispersed employees will help organizations to achieve revenue growth 25% faster than competitors by 2023. Means so as to remain competitive and deliver seamless work experience, organizations in sectors from retail to education will require to reconfigure delivery models to embrace distributed services. 

Development team augmentation is a way to ramp up a software development with tech experts regardless of their location. Hiring an external team, you delegate the responsibility for hiring and HR matters to a third-party service provider who offers full-time staff. Simply, all necessary processes such as recruiting, onboarding, training and managing dedicated experts lie on outstaffing vendor’s shoulders, while as a product executive you can focus on business goals.

2. Rise Of Cloud Computing-

Cloud native platforms is another trend that will serve as a foundation for more than 95% of new digital initiatives by 2025. CNP has an architecture aimed at leveraging the automated cloud services by adding just some cloud attributes to your existing legacy system. When you use CPNs, it improves the delivery time and decreases costs. Being a part of global cloud adoption trends, CPNs serve as a way to optimize your infrastructure, improve operations and accelerate digital transformation. This trend reflected in numbers: According to the statista reports, the worldwide public cloud computing market keeps growing and is expected to reach $482 billion in 2022. In 2019, by comparison, the market size amounted to $243 billion. 

How to take advantage of cloud computing?

Some of the important benefits are- 

• Reduced costs for maintenance and support
• Advanced data recovery mechanisms in case of data loss or corruption
• Stable and continuous releases with minimal downtime and no production interruptions

List depends on the method you choose for adopting and computing services.

Cloud software re-architecting- It is popular among businesses that undergo expansions and transformations. Redesigning of existing architecture is important to improve a system’s performance, scalability and security. 

Cloud migration- It includes evaluating the software architecture and developing an action plan to implement cloud solution so as to achieve cost savings, reliability, security and other benefits that cloud computing can provide.

Cloud native development- It can minimize efforts for infrastructure management by automating networks, servers and operating systems. This way developed apps can be scaled from scratched and have the ability to be released fast.

3. Robotic Process Automation-

Robotic process automation refers to the use of software or web app to automate complex business operations and routine actions. RPA solutions are mostly used for customer support, inventory management, payroll processing and other use cases. RPA implementation is popular after 2015, and its increase is strongly connected with the machine learning development. The pandemic outbreak accelerated global RPA adoption and has contributed to its being mentioned among software development outsourcing trends.

How To Choose The Right Headless CMS?

We have seen a major shift in CMS(Content management system) in recent years. Lots of companies are through digital transformation so they are looking for ways to become more agile and deliver modern digital experiences. They want to adapt new technologies and methodologies, like cloud, microservices, front-end frameworks, or DevOps. Eventually, they realize their legacy content management solutions hold them back. If you’re also facing the same issue, then this blog is for you. Here we’ll discuss how to choose the right headless CMS.

How To Choose The Right Headless CMS?

1. Know The Headless Architecture-

If you’re well known about traditional CMSs, it is important to understand how they’re different from headless. Let’s see the difference in architecture-

Monolithc Vs. Microservices Architecture-

Monolith Vs. Microservices Architecture

Traditional CMSs combined content management and its presentation in a single coupled solution. They control the content presented on the website, using proprietary templating engines. They tend to add various extra marketing or commerce capabilities. The result is a big monolith where CMS plays a central role.

Headless CMS manage content and provide it through API. Meaning that, the content can be delivered to any digital channel including mobile, online store, website, chatbot etc. This is a popular approach among programmers who want to use progressive front-end frameworks and build mobile apps. Headless CMSs fit the microservices architecture perfectly and in this model, you build digital product by connecting specialized services from various vendors through APIs.

In microservices architecture, you build a digital experience stack around a digital product instead of building a product around a particular CMS. Meaning that, you don’t need to throw your digital product when you decide to switch to another CMS.

Web First And Content First Approach-

Traditional CMSs were for the web. They’re built around web-specific concepts like sitemap, website and pages. They focussed on providing high control over design to business users that may be empowering, but huge control may lead to inconsistency of brand.

Whereas, headless CMSs are designed for the content-first approach and this  starts with content modeling that helps you to define content structure so that it can be reused across various devices. It provides more flexibility and needs a change in how you think about and work with content.

2. Pinpoint Your Business Concerns-

Sorting business requirements is an important factor in choosing a Headless CMS because it is all about getting your requirements fulfilled. Here are some of the business cases and requirements to choose headless CMS-

• For implementation of modern technology for digital experience
• To get higher agility, productivity and consistency of brand
• For personalized omnichannel experience
• To increase the efficiency of content operations
• For making business future-proof

3. Identify Requirements Of Key Stakeholders-

Why Should You Choose React With Rails For Web Apps Development?

 

You know that ReactJS is a popular Javascript library used for developing frontend for user interactive web apps. It offers the flexibility to create reusable React components. One of the main goal of ReactJS is to develop fast, scalable and straightforward apps. Ruby on Rails is an open source web framework built on the top of Ruby language. It is a collection of libraries that provides a solution for the tasks used repeatedly in the project like creation of menus, tables or forms. Ruby on rails provides flexibility and saves your time to develop a scalable app. It runs on server so can be classified as a backend development platform. This is just an individual overview ReactJS and Rails. Here we’ll discuss why you should use React with rails. But before digging to it, let’s know the points that you should consider while choosing to use react with rails.

Points To Consider Before Choosing React With Rails-

Selecting the best technical stack is a tricky task and you must be thoroughly familiar with the project’s requirements. Different people advice according to their situation. Considering that here we’ve mentioned general responsibilities: why and when you should use React with ruby on rails.

• Detailed understanding of product
• Product’s requirements and complexity
• Business requirements of product
• Budget and timeframe
• Ensure that you’re not overkilling or underpowering the product
• Availability of technical expertise with ReactJS and Rails
• Security and scalability of product

Why Should You Use React With Rails?

1. Reliable Technologies-

The combination of Rails and ReactJs is used and tested by well known platforms like Shopify, Github, Airbnb, Twitter, Crunchbase and so on. Combination of Ruby on rails and react has proven to develop the most reliable and dynamic apps due to their individual strength.

2. Rapid Development-

Ruby on rails has various built-in modules and code libraries that reduce efforts and development time of developers. Also it improves the communication with frontend libraries of ReactJS. It allows the cost reduction in development as lesser time is being used on product development.

3. Development Pace And Quality-

If you’re looking to build a freemium model-based app, ReactJS with RoR is the best combination. Also, if your main concern is time to market, then go with ReactJS with Rails. Combination of these technologies improves the quality of your product and pace of development too.

4. Reduced Server Request Time-

Loading time of web application is important and it is necessary to kept in mind. No user will like to wait for its request made. Hence, a web application having high loading time can prompt losing some of its users. To avoid this, developers should reduce the server request time and get quick response. As per the professionals, Ruby on rails has successfully reduced the loading time of app to 80% – 90%.

5. Less Memory Usage And Increases Performance-

If you’re facing issues about unnecessary space being occupied, you can choose to deploy your application using React with Rails API. It works as expected and gave improved results with increased performance.

Here you will get to know the details of best practices of golang that enhance the code quality. 

Also know the reasons to use go for nativemobile app development at- Why You Should Go For Native Mobile App Development?

Golang Best Practices To Follow In 2021-

1. Don’t Repeat Till It Is Necessary-

Creating a common file to  store structure and later use those saved structures for controllers and models is really a great thought. Just ensure to follow Go project structure best practices.

Get it from the below example-

type binWriter struct {
   w io.Writer
   Size int64
   err error
}

//Write writes a value to provided writer in small endian form.
func (w *binWriter) Write(v interface{}) {
  if w.err != nil {
   return
   }
if w.err = binary.Writer(w.w, binary.LittleEndian, v); w.err == nil {
   W.size += int64(binary.Size(v))
}
}

Here you can avoid repetition by using binWriter,

func (g *Gopher) WriteTo(w io.Writer) (int64, error) {
  bw := &binWriter{w: w}
  bw.Write(int32(len(g.Name)))
  bw.Write([]byte(g.Name))
  bw.Write(int64(g.AgeYears))
  Return bw.size, bw.err
}

2. Give Priority To Necessary Code-

If you have important information such as build tags, license information, package documentation, then initially describe it. You can divide the Import statements related groups. The standard library packages exist in the first group.

import (
    “ fmt”
      “io”
       “log”
       “golang.org/x/net/websocket”
)

The remaining code begins with the important types and ends with helper function and types.

3. Managing Multiple Files In The Same package-

Should you break a particular package into various files?

• Prevent long files

Standard library’s net/http package includes 15734 lines in 47 files.

• Divide code and tests

net/http/cookie.go and net/http/cookie_test.go are parts of http package.

Ideally, test code is compiled on at test time.

Divided package documentation

When a package has more than one file, it is an agreement to create a doc.go compromising the package documentation.

4. Say No To Concurrency In APIs-

func doConcurrently(job string, err chan error) {
  go func() {
      fmt.Println(“doing job”, job)
      time.Sleep(1 * time.Second)
      err <- errors.New(“something went wrong!”)
}()
}

func main() {
    jobs := [ ]string{“one”, “two”, “three”}

    errc := make(chan error)
    for _, job := range jobs {
      doConcurrently(job, errc)
}
for _= range jobs {
    if err := <-errc; err !=nil {
      fmt.Println(err)
}
}
}

If needed, how to use it sequentially?

func do(job string) err {
 fmt.Println(“doing job”, job)
 time.Sleep(1 * time.Second)
 return errors.new(“something went wrong!”)
}
func main() {
  Jobs := [ ]string{“one”, “two”, “three”}

errc := make(chan error)
for _, job := range jobs {
    go func(job string) {
     errc <- do(job)
}(job)
for _= range jobs {
  if err := <-errc; err != nil {
    fmt.Println(err)
}
}
}

Reveal synchronous APIs as calling them simultaneously is easy and reliable.

5. Avoid Goroutine Leaks-

func sendMsg(msg, addr string) error {
  conn, err := net.Dial(“tcp”, addr)
  if err != nil {
  return err
}
defer conn.Close()
_, err = fmt.Fprint(conn, msg)
return err
}
func main() {
addr := [ ]string{“localhost:808”, “http:google.com”}
err := broadcastMsg(“hi”, addr)
time.Sleep(time.Second)
if err != nil {
  fmt.Println(err)
   return
}
fmt.Println(“something went fine”)
}

func broadcastMsg(msg string, addrs [ ]string) error {
 errc :=make(chan error)
 for _, addr := range addrs {
    go func(addr string){
    errc <- sendMsg(msg, addr)
    fmt.Println(“done”)
   }(addr)
}
for _= range addrs {
  if err := <-errc; err != nil {
  return err
}
}
return nil
}

• Goroutine carries a source to the chan
• The goroutine is blocked on chan write
• chan will never be accumulated with garbage

 func broadcastMsg(msg string, addrs [ ]string) error {
  errc := make(chan error, len(addrs))
  for _, addr := range address {
   go func(addr string) {
     errc <- sendMsg(msg, addr)
     fmt.Println(“done”)
}(addr)
}
  for _= range addrs {
    if err := <-errc; err !=nil {
    return err 
} } 
return nil
}

If the capacity of the channel stays unpredicted, what to do?

func broadcastMsg(msg string, addrs [ ]string) error {
  errc := make(chan error)
  quit := make(chan struct{})
defer close(quit)

for _, addr := range address {
  go func(addr string) {
  select {
  case errc <- sendMsg(msg, addr):
  fmt.Println(“done”)
  case <-quit :
   fmt.Println(“quit”)
} }(addr)
}
