Configuration Files - use a JavaScript file to specify configuration information for an entire directory and all of its subdirectories. This can be in the form of an eslint.config.js file which ESLint will look for and read automatically, or you can specify a configuration file on the command line.

There are two primary ways to configure ESLint: Configuration Comments - use JavaScript comments to embed configuration information directly into a file. Configuration Files - use a JavaScript, JSON or YAML file to specify configuration information for an entire directory and all of its subdirectories. This can be in the form of an .eslintrc.* file or an eslintConfig field in a package.json file, both of which ESLint will look for and read automatically, or you can specify a configuration file on the command line.

If the rule configuration is an ... that individual rule. For example, the below .eslintrc.json tells ESLint to error out when any line of code is more than ......

for example, after you run eslint, you might see something like: Warning: 1:2 warning More than 2 blank lines not allowed no-multiple-empty-lines Error: 2:34 error 'pick' is defined but never used no-unused-vars you can set the error level in your .eslintrc.js (under "rules") like: "semi": 2

The three error levels allow you fine-grained control over how ESLint applies rules (for more configuration options and details, see the configuration docs). Your .eslintrc.{js,yml,json} configuration file will also include the line:

npm install @eslint/eslintrc -D # or yarn add @eslint/eslintrc -D # or pnpm install @eslint/eslintrc -D # or bun install @eslint/eslintrc -D

This page is a quick-start for ESLint's new "flat" config format to go from zero to linting with our recommended rules on your TypeScript code as quickly as possible.

While you should file an issue with the particular plugin, you can manually patch the plugin to work in ESLint v9.x using the compatibility utilities. In eslintrc files, importing a custom parser is similar to importing a plugin: you use a string to specify the name of the parser.

September 18, 2023 - The following is an example of a simple .eslintrc.js file: module.exports = { rules: { 'no-unused-vars': 'error', 'no-console-log': 'warn', }, }; This configuration file enables the no-unused-vars rule with an error severity, and the no-console-log rule with a warn severity. You can also use configuration files to extend other configuration files. For example, the following configuration file extends the eslint-config-airbnb configuration file:

After running eslint --init, you’ll have a .eslintrc file in your directory.

how to set up eslint, how to create the .eslintrc file, etc etc… but I didn’t need that. I have an existing project, I just want to configure VSCode to use ESLint instead of Prettier.

July 20, 2023 - This behavior could be inverted if you run the eslint binary with ESLINT_USE_FLAT_CONFIG=false. In the eslintrc, we could only write CJS syntax. With the new flat config, we can write either ESM or CJS. Writting one or another will depends on your ecosystem. ... For the sake of this tutorial, I'm going to write most of the examples using ESM syntax.
