Bun 1.0 is officially released, lightning fast, far ahead!

Hanish Rao — Tue, 12 Sep 2023 12:39:32 +0000

On September 2023, 9, the runtime Bun officially released version 8.1, marking the official entry of the project created by former Facebook engineers into stable production usability. Bun's vision is to make front-end development "lightning fast" through deep integration. Can this new force shake the status of the established overlord Node and become the next generation of front-end development standards? Let's get a glimpse of the power of this new star.

Bun is more than just a runtime. It is also:

A package manager (like Yarn, NPM, PNPM)
A build tool (similar to Webpack, ESBuild, Parcel)
A test runner

and more..

So Bun can install dependencies by reading package.json. Bun can also run scripts. Whatever it does, it's faster than other tools. Bun has experimented with many aspects of the JavaScript ecosystem, with a focus on performance. It prioritizes support for standard web APIs such as Fetch. It also supports many Node.js APIs, making it compatible with most NPM packages.

To install Bun:

// npm
npm install -g bun

// brew
brew tap oven-sh/bun
brew install bun

// curl
curl -fsSL https://bun.sh/install | bash

// docker
docker pull oven/bun
docker run --rm --init --ulimit memlock=-1:-1 oven/bun

Update Bun:

bun upgrade

Here's a look at what Bun is and what updates 1.0 brings!

Bun: The all-around toolkit

JavaScript is mature, fast-moving, and has a vibrant and passionate developer community. However, since the release of Node .js 14 years ago, JavaScript's toolchain has become larger and more complex. This is because in the process of development, various tools are gradually added, but there is no unified centralized planning, resulting in the lack of integrity and efficiency of the toolchain, which becomes slow and complex.

Why did Bun appear?

Bun's goal is simple: to eliminate the slowness and complexity of JavaScript toolchains, but at the same time retain the benefits of JavaScript itself. Bun wants to allow developers to continue using their favorite libraries and frameworks without having to abandon the specifications and conventions they are already familiar with.

To achieve this, it may be necessary to give up some tools that become unnecessary after using Bun:

Node.js: A drop-in alternative to Bun, so the following tools are no longer needed:

node
npx:Bun's command is 5 times faster than .bunxnpx
nodemon: Bun has a built-in listening mode and does not need to be used .nodemon
dotenv,:Bun supports the configuration of reading files by default.cross-env.env

Transpiler: Bun can run 、、、 and files, so the following tools are no longer needed: .js.ts、.cjs.mjs.jsx.tsx

tsc: You can still keep it for type checking!
babel,,: No more transpiling with Babel..babelrc@babel/preset-*
ts-node,:Bun can run TypeScript files directly.ts-node-esm
tsx: Bun can run TypeScript's JSX files directly.

Build tools: Bun has top-notch performance and an esbuild-compatible plugin API, so the following tools are no longer needed:

esbuild
webpack
parcel, .parcelrc
rollup, rollup.config.js

Package manager: Bun is an npm-compatible package manager that can use familiar commands. It can read files and write dependencies to directories, behaving similarly to other package managers, so it can replace the following tools: package.jsonnode_modules

npm, , .npmrcpackage-lock.json
yarn,yarn.lock
pnpm, pnpm.lockpnpm-workspace.yaml
lern

Test Library: Bun is a Jest-enabled test runner with features such as snapshot testing, simulation, and code coverage, so the following test-related tools are no longer needed:

jest, jest.config.js
ts-jest, , @swc/jestbabel-jest
jest-extended
vitest, vitest.config.ts

Although these tools have their own advantages, using them often requires them all to be integrated, which can lead to a slow and complex development process. Bun provides the best developer experience by being a single toolkit, from performance to API design.

Building with Node.js: Navigating the World of Best Practices and Best Tools

Hanish Rao — Sat, 14 Jan 2023 02:04:41 +0000

Node.js is a popular open-source, cross-platform JavaScript runtime that allows developers to build fast and scalable network applications. As with any technology, there are certain best practices that should be followed when working with Node.js to ensure that your code is clean, maintainable, and performant. In this blog post, I'll be discussing some of the best practices for Node.js development.

Asynchronous Code

Node.js is built on a non-blocking, event-driven architecture, which means that it's designed to handle a high number of concurrent connections. To take full advantage of this architecture, it's important to use asynchronous code whenever possible. This means using callbacks, promises, and async/await to avoid blocking the event loop.
In Node.js, asynchronous code can be written using callbacks, promises, and async/await.

Here is an example of using callbacks to perform an asynchronous operation:

const fs = require('fs');

fs.readFile('file.txt', (err, data) => {
  if (err) {
    console.error(err);
    return;
  }

  console.log(data.toString());
});

console.log('This line will be executed before the file is read.');

In this example, the fs.readFile function is used to read a file asynchronously. The function takes a callback that will be executed once the file has been read. This allows the rest of the code to continue executing while the file is being read, rather than blocking the event loop.

Here is an example of using promises to perform an asynchronous operation:

In this example, the fs.readFile function is wrapped in a promise. The promise is resolved with the contents of the file, or rejected with an error if one occurs. This allows the code to be written in a more synchronous-looking style while still being non-blocking.

Here is an example of using async/await to perform an asynchronous operation:

const fs = require('fs');

const readFile = file => {
  return new Promise((resolve, reject) => {
    fs.readFile(file, (err, data) => {
      if (err) {
        reject(err);
        return;
      }

      resolve(data.toString());
    });
  });
};

async function main() {
  try {
    const data = await readFile('file.txt');
    console.log(data);
  } catch (err) {
    console.error(err);
  }
}

main();
console.log('This line will be executed before the file is read.');

In this example, the readFile function is marked as async, allowing it to be called using the await keyword. This allows the code to be written in a synchronous-looking style while still being non-blocking.

It's worth noting that, in all these examples, the last line of code (console.log('This line will be executed before the file is read.');) will be executed before the file is read, because the readFile operation is non-blocking.

Linter

A linter is a tool that checks your code for potential errors and stylistic inconsistencies. Using a linter in your Node.js development can help you catch errors early on and ensure that your code follows a consistent style. There are several popular linters for Node.js, including ESLint and JSHint.

Here is an example of how to use ESLint in a Node.js project:

Install ESLint and the Node.js configuration:

npm install eslint eslint-config-node

Create an ESLint configuration file, such as .eslintrc.json in the root of your project, with the following contents:

{
    "extends": "node"
}

Add a script to your package.json to lint your code:

"scripts": {
    "lint": "eslint ."
}

Run the lint script to check your code for errors and inconsistencies:

npm run lint

ESLint will check your code for errors and inconsistencies according to the rules set in the configuration file, and will output any issues it finds.

You can also configure ESLint to automatically fix some of the issues it finds by running the --fix flag. You can add it to your script in package.json

"scripts": {
    "lint": "eslint --fix ."
}

It's important to note that ESLint is highly configurable, you can customize the rules and settings to fit the needs of your project, and you can also use plugins to add additional functionality.

Package Manager

A package manager is a tool that makes it easy to manage the dependencies in your Node.js project. The most popular package manager for Node.js is npm, which comes pre-installed with Node.js. Using a package manager can help you keep track of the versions of the packages you're using and make it easy to update or roll back to a specific version if necessary.

Here is an example of how to use npm in a Node.js project:

Initialize an npm package by creating a package.json file in your project's root directory:

npm init

Install a package as a dependency:

npm install <package-name>

For example, to install the "request" package, which makes it easy to make HTTP requests, you would run

npm install request

Use the package in your code:

const request = require('request');

request('https://www.example.com', (err, res, body) => {
  console.log(body);
});

Keep track of the packages you are using by saving it to package.json

npm install <package-name> --save

Update packages to their latest version

npm update

Uninstall a package

npm uninstall <package-name>

With npm, you can easily manage the packages you're using in your Node.js project and keep track of the versions you're using. You can also use npm to update or roll back to a specific version of a package if necessary.

Framework

Node.js frameworks like Express, Koa, and Hapi provide a set of abstractions and conventions that can help you structure your code and make it easier to build scalable and maintainable applications. Using a framework can help you avoid reinventing the wheel and can provide a set of best practices that you can follow.

Here is an example of how to use the Express framework in a Node.js project:

Install Express:

npm install express

Import Express in your application:

const express = require('express');
const app = express();

Define routes:

app.get('/', (req, res) => {
  res.send('Hello, World!');
});

Start the server:

app.listen(3000, () => {
  console.log('Server started on port 3000');
});

Use middlewares

const bodyParser = require('body-parser');
app.use(bodyParser.json());

Use template engines

const ejs = require('ejs');
app.set('view engine', 'ejs');
app.get('/', (req, res) => {
  res.render('index', { title: 'My App' });
});

In this example, I've created a simple server using Express that listens on port

Process Manager

A process manager is a tool that helps you manage the processes that your Node.js application runs on. The most popular process manager for Node.js is PM2, which allows you to easily start, stop, and restart your application, as well as manage logs, monitoring and clustering.

Here is an example of how to use PM2 in a Node.js project:

Install PM2:

npm install pm2 -g

Start your application:

pm2 start app.js

Monitor your application:

pm2 monit

View logs:

pm2 logs

Restart your application:

pm2 restart app

Stop your application:

pm2 stop app

Delete your application from PM2:

pm2 delete app

Generate startup script

pm2 startup

With PM2, you can easily manage your Node.js application and ensure that it's always running smoothly. PM2 also allows you to run multiple instances of your application and load balance the incoming traffic across all instances. Additionally, PM2 provides monitoring and logging features, which can be very helpful in debugging and troubleshooting issues in your application.

Testing Framework

Writing tests for your Node.js code is a crucial step in ensuring that your code is reliable and bug-free. There are several popular testing frameworks for Node.js, including Jest, Mocha, and Chai.

Here is an example of how to use Jest in a Node.js project:

Install Jest:

npm install jest --save-dev

Create a test file, for example, sum.test.js in the root of your project:

const sum = require('./sum');

test('adds 1 + 2 to equal 3', () => {
  expect(sum(1, 2)).toBe(3);
});

Add a script to your package.json to run your tests:

"scripts": {
    "test": "jest"
}

Run your tests:

npm test

Jest will automatically detect and run any test files that match the pattern *.test.js or *.spec.js. Jest also provides a powerful assertion library, that allows you to easily test the output of your code, and it also provides a rich set of features such as test coverage, watch mode, and snapshot testing.

Another popular testing framework for Node.js is Mocha, which is a feature-rich JavaScript test framework running on Node.js and in the browser, making asynchronous testing simple and fun. Mocha tests run serially, allowing for flexible and accurate reporting, while mapping uncaught exceptions to the correct test cases.

And Chai, is a BDD/TDD assertion library for node and the browser that can be delightfully paired with any JavaScript testing framework. Chai provides several interfaces that allow the developer to choose the most comfortable.

It's important to note that choosing a testing framework depends.

Optimize Performance

As your Node.js application grows, it's important to keep an eye on performance. Use performance monitoring tools such as Node-clinic and New Relic to help you identify bottlenecks and optimize your code.

Here are some examples of how to optimize performance in a Node.js application:

Performance monitoring tools: There are several performance monitoring tools available for Node.js, such as Node-clinic and New Relic. These tools can help you identify bottlenecks in your code, such as slow database queries or memory leaks.
Profiler: A profiler is a tool that can help you understand the performance characteristics of your application by measuring the time taken by different parts of your code. One of the most popular profilers for Node.js is the built-in v8 profiler.
Load balancer: A load balancer is a tool that can distribute incoming traffic across multiple instances of your application. This can help reduce the load on any one instance and improve overall performance.
Caching: Caching can help to reduce the number of requests made to a server by storing the results of a request and returning them when the same request is made in the future.
Content Delivery Network (CDN): CDN is a network of servers distributed around the world that can be used to deliver content to users more quickly.

By following these best practices, you'll be able to write clean, maintainable, and performant code in Node.js. However, it's important to remember that best practices are just a guide, and you should always use your own judgement when deciding how to structure your code.
