Hello everyone, If you have ever worked on a open source project or any project in general where multiple people collaborate together then you might have faced issues like commit convention does not match. There is no proper/even indentation to the code or simply the difference of ' ' and " " in the code.
This actually makes the codebase messier. Now how can you overcome that? So there are many predifined plugins/libraries which help you in overcoming all the abouve mentioned problems.
So in this blog we are going to see the following things
- ESLint (For generalizing the style standards for js code)
- Prettier (For indenting your codebase evenly)
- Husky (Running the tests and commit convention check in local machine before commiting so that you don't face linting and test fail errors afterwords)
Note: This linting style are of my personal choice. You can tweak in the codes to fit in your linting and style standards :)
Extension for VS code
(This is my personal recommendation. It's personal choice)
If you want to follow along then I would recommend you to download it. For downloading you can copy the code given with the name below, into the extension search box and the extension will pop up. Click on install and it will get added to your vs code.
- Eslint ==>
dbaeumer.vscode-eslint - Prettier ==>
esbenp.prettier-vscode
Initializations & Installations
Open the project in the terminal and run the following commands by the same sequence.
- Run the following command (if not clonned and started fresh in local machine)
git init
- Run the following command (This is initialize package.json in your project)
npm init -y
- Run the following command (This will creat node modules and packge-lock.json)
npm i --save-dev eslint eslint-config-prettier eslint-plugin-prettier husky lint-staged prettier
Eslint
Create file .eslintrc.json in the root of the project and paste the following in it
{
"env": {
"es2020": true,
"node": true
},
"extends": [
"eslint:recommended",
"plugin:prettier/recommended"
],
"rules": {
"linebreak-style": ["error", "unix"],
"quotes": ["error", "single", { "allowTemplateLiterals": true }],
"semi": ["error", "always"],
"prefer-const": "error",
"eqeqeq": ["error", "always"],
"curly": ["error"]
},
}
Prettier
Now create .prettierrc in the root of the project file and paste the following in the file
{
"endOfLine": "lf",
"useTabs": true,
"singleQuote": true
}
Git Ignore
Now create .gitignore file in the root of the project and paste the following in the file
/node_modules/
.env
Huskey
Now create .huskyrc file in the root of the project and paste the following in it
{
"hooks": {
"pre-commit": "lint-staged"
}
}
Now go to package.json and add this at the end before the last }
"lint-staged": {
"*.js": ["eslint --fix", "prettier --write"]
}
Now run the following commands one by one in the terminal
- Installing husky to the local project directory
npm install husky --save-dev
- Intall husky package
npx husky install
- Initialize husky package and install dependencies
npx husky-init && npm install
This will create husky folder
Now go to pre-commit file in the husky folder and delete the npm test command. As we don't have tests as of now
- Installing conventional commit style
npm install --save-dev @commitlint/cli @commitlint/config-conventional
- Add the command to commitlint.config.js file
echo "module.exports = {extends: ['@commitlint/config-conventional']}" > commitlint.config.js
- Adding husky reference commit message library
npx husky add .husky/commit-msg 'npx --no-install commitlint --edit "$1"'
That's it !!! You have setup your project with cool tools which would ease your work as a maintainer or reviewer. This will take care of all of your style guidelines.
You are all set-up with your js project. If you can to configure it with js follow Nicholas Carrigan Notes
