About Standard JS
JavaScript Standard Style is a zero-configuration linter and formatter that enforces consistent code style across projects. It eliminates the need for configuration files, automatically formats code with a single command, and catches style issues early to streamline code reviews. Ideal for teams and open-source projects seeking simplicity and clarity.
FAQ
You can install JavaScript Standard Style globally by running `npm install standard --global` in Terminal. Alternatively, you can install it locally for a single project with `npm install standard --save-dev`. Note that Node.js and npm must be installed to run these commands.
After installing, you can check the style of all JavaScript files in the current directory by running `standard`. If installed locally, use `npx standard` instead. You can also specify directories using glob patterns, like `standard "src/util/**/*.js" "test/**/*.js"`.
Yes, you can use `standard --fix` to automatically fix most style issues. Some errors, like unhandled errors, must be fixed manually. The tool will suggest running `standard --fix` when it detects fixable problems.
Certain paths like `node_modules/`, `coverage/`, and files starting with `.` are automatically ignored. To ignore additional paths, add a `standard.ignore` property in your `package.json` with an array of glob patterns.
Yes, since JavaScript Standard Style uses ESLint under the hood, you can disable rules using ESLint comments. For example, disable all rules on a line with `// eslint-disable-line` or disable a specific rule like `// eslint-disable-line no-use-before-define`.
If a library adds global variables (e.g., Mocha's `describe`, `it`), you can prevent "variable is not defined" errors by adding a comment at the top of your file: `/* global myVar1, myVar2 */`. Alternatively, use the `--global` flag or add globals in `package.json` under the `standard` property.
Yes, you can add a badge to your project's README to indicate it uses JavaScript Standard Style. Example badges include `[](https://github.com/standard/standard)` or `[](https://standardjs.com)`.
Yes, JavaScript Standard Style supports the latest ECMAScript features (ES8/ES2017) and Stage 4 proposals. For experimental features, you can use a custom parser like `@babel/eslint-parser` by running `standard --parser @babel/eslint-parser` or adding it to your `package.json` under the `standard` property.
