semistandard
✓ { "extends": "semistandard" }
✗ import semistandard from 'eslint-config-semistandard';
This package provides an ESLint shareable configuration. It is referenced as a string within the `extends` array of your ESLint configuration file (e.g., `.eslintrc.json` or `.eslintrc.js`), not imported as a JavaScript module.
Installs `eslint-config-semistandard` along with all necessary peer dependencies, then shows how to configure an `.eslintrc.json` file to extend the `semistandard` configuration, and provides a simple JavaScript file to demonstrate its application.
npm install --save-dev eslint eslint-config-semistandard eslint-plugin-import eslint-plugin-n eslint-plugin-promise eslint-config-standard
// .eslintrc.json
{
"extends": "semistandard",
"env": {
"browser": true,
"node": true,
"es2021": true
}
}
// index.js (example file to lint)
const path = require('path');
const greet = (name) => {
console.log(`Hello, ${name}!`);
};
greet('World');
// Linting this file will enforce semicolon usage and other semistandard rules.
// For example, missing semicolons will be reported.
// To run: `npx eslint index.js`

Known issues
breakingVersion 16.0.0 was a breaking change, updating its base to `eslint-config-standard` version 16.x. Projects upgrading from older versions must also ensure their `eslint-config-standard` peer dependency is updated accordingly and review for any rule changes introduced by `standard`.fixUpdate `eslint-config-standard` to version `^16.0.0` or higher, compatible with `eslint-config-semistandard` v16.x. Review the `eslint-config-standard` changelog for specific rule changes.
affects: >=16.0.0 <17.0.0
breakingWith version 16.0.0, the recommended ESLint configuration filename was changed from `.eslintrc.js` to `eslintrc.json` to align with `eslint-config-standard` practices. While `.eslintrc.js` might still work, using `.eslintrc.json` is the new standard.fixRename your ESLint configuration file from `.eslintrc.js` to `.eslintrc.json` if you are using an older JavaScript-based config, or update your build tools/IDE to recognize the new `.eslintrc.json` filename.
affects: >=16.0.0
breakingVersion 17.0.0 is based on `eslint-config-standard` version 17.0.0. This implies potential breaking changes or new rules inherited from the upstream `standard` configuration. All peer dependencies, especially `eslint-config-standard`, must be updated to their compatible major versions.fixEnsure `eslint-config-standard` is installed at version `^17.0.0`. Review the changelog for `eslint-config-standard` v17.0.0 for details on any new rules or modifications that might affect your codebase.
affects: >=17.0.0
gotchaThis package, like many ESLint shareable configs, relies on several peer dependencies (e.g., `eslint`, `eslint-config-standard`, `eslint-plugin-import`). Failing to install these explicitly, or installing incompatible versions, will lead to errors.fixAlways install all listed peer dependencies alongside `eslint-config-semistandard` at compatible versions. Use `npm info eslint-config-semistandard peerDependencies` to check current requirements, and `npm install --save-dev [all-peer-deps]`.

Errors
Common errors & fixes
Error: Failed to load config 'semistandard' to extend from.
The `eslint-config-semistandard` package is not installed or not resolvable by ESLint.
fixEnsure `eslint-config-semistandard` is installed: `npm install --save-dev eslint-config-semistandard`.
ESLint: The 'extends' property in your ESLint configuration specifies a configuration that is incompatible with your current ESLint version.
The installed ESLint version is not compatible with the `eslint-config-semistandard` or its base `eslint-config-standard` package's peer dependency requirements.
fixCheck the `peerDependencies` of `eslint-config-semistandard` and `eslint-config-standard` (e.g., `npm info eslint-config-semistandard peerDependencies`) and install a compatible `eslint` version, typically `npm install --save-dev eslint@^8.13.0` for recent versions.
ESLint: Rule 'promise/always-return' is not found.
One or more of the required ESLint plugins (e.g., `eslint-plugin-promise`, `eslint-plugin-import`, `eslint-plugin-n`) are missing or an incompatible version is installed.
fixInstall all necessary peer dependencies at their specified versions: `npm install --save-dev eslint-plugin-import@^2.26.0 eslint-plugin-n@^15.0.0 eslint-plugin-promise@^6.0.0`.
