Prettier is a popular code formatter that ensures consistent code styling by automatically formatting your code. It enforces a unified coding style across your project, eliminating debates about code formatting and enhancing collaboration among developers.
Prettier follows a set of opinionated formatting rules, removing the need for manual configuration and discussions about coding style.
Prettier supports multiple programming languages, including JavaScript, TypeScript, HTML, CSS, and more.
Prettier can be integrated with ESLint to combine the benefits of automatic code formatting and linting.
Install Prettier as a development dependency in your project:
npm install --save-dev prettier
Create a Prettier configuration file, typically named .prettierrc
:
// .prettierrc
{
"semi": false,
"singleQuote": true,
"tabWidth": 2,
// Your configuration here
}
Configure Prettier to omit semicolons at the end of statements:
// .prettierrc
{
"semi": false
}
Enforce the use of single quotes for strings:
// .prettierrc
{
"singleQuote": true
}
Run Prettier on your project with the following command:
npx prettier --write .
For seamless integration with ESLint, install the prettier-eslint package:
npm install --save-dev prettier-eslint
Run Prettier through ESLint:
npx eslint --fix .
Install the Prettier extension for VS Code and configure it to format code on save.
Prettier simplifies the process of maintaining code consistency by automating code formatting. Its opinionated approach reduces configuration overhead, allowing developers to focus on writing code rather than debating coding styles.
