tslint-loader

library3.5.4jsnpmunverified

Webpack loader for TSLint, version 3.5.4, last updated in 2019. Integrates TSLint into webpack build pipeline to lint TypeScript files during compilation. Supports custom config files, type-checked rules, formatters, and file output. Compatible with webpack 1-4, but requires TSLint >=4.0.0. Key differentiator: seamlessly adds linting as a pre-loader step in webpack, with options to emit errors or fail builds on hints. Less active now due to TSLint deprecation in favor of ESLint with TypeScript.

tslint-loader

✓ // In webpack config, use loader string 'tslint-loader'

✗ import tslintLoader from 'tslint-loader'

This is a webpack loader, not a JavaScript import. It is referenced by name in webpack configuration.

Configures tslint-loader as a pre-loader in webpack to lint all .ts files before compilation, with options for type checking and error handling.

// webpack.config.js module.exports = { module: { rules: [ { test: /\.ts$/, enforce: 'pre', use: [ { loader: 'tslint-loader', options: { configFile: 'tslint.json', emitErrors: true, failOnHint: true, typeCheck: true, tsConfigFile: 'tsconfig.json' } } ] } ] } }

Debug

Known issues

deprecatedTSLint is deprecated in favor of ESLint with TypeScript. Consider migrating to eslint-loader or @typescript-eslint.

fix

Use eslint-loader with @typescript-eslint/parser and @typescript-eslint/eslint-plugin.

affects: >=3.0.0

breakingRequires TSLint >=4.0.0, not compatible with TSLint 3.x.

fix

Update TSLint to version 4.0.0 or higher.

affects: >=3.0.0

gotchaThe loader must be applied as a pre-loader using 'enforce: pre' to ensure it runs before compilation.

fix

Set enforce: 'pre' in the rule configuration.

affects: >=2.0.0

gotchaWebpack 1 uses 'preLoaders' and 'tslint' config property, while webpack 2+ uses 'rules'.

fix

Use appropriate configuration syntax for your webpack version.

affects: >=3.0.0

gotchaSetting 'typeCheck: true' requires a valid tsconfig.json file and may slow down compilation.

fix

Ensure tsconfig.json exists and contains necessary compiler options.

affects: >=1.0.0
