eslint-config-typestrict

library1.0.5jsnpmunverified

An ESLint shareable configuration focused on maximizing TypeScript type safety by enabling strict rules that catch bugs. Version 1.0.5 is the latest stable, with low release cadence. Combines rules from @typescript-eslint/eslint-plugin and eslint-plugin-sonarjs, emphasizing type-correctness and runtime error prevention over code style. Unlike other configs (e.g., eslint-config-airbnb-typescript), TypeStrict is minimalist and bug-focused, requiring manual peer dependency installation and strict tsconfig setting.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

typestrict

✓ extends: 'typestrict' in .eslintrc.json

✗ import typestrict from 'eslint-config-typestrict'

Extend via ESLint config, not import statement.

default config

✓ module.exports = { extends: 'typestrict' }

✗ module.exports = require('eslint-config-typestrict')

The package is an ESLint config, not a module with exported rules. Use 'extends' in ESLint configuration.

peer dependencies

✓ npm install --save-dev @typescript-eslint/eslint-plugin eslint-plugin-sonarjs

✗ npm install --save-dev eslint-config-typestrict

Peer dependencies must be installed manually.

Shows how to configure ESLint with typestrict config, requiring manual installation of peer plugins and strict tsconfig.

// .eslintrc.json { "extends": "typestrict", "parser": "@typescript-eslint/parser", "parserOptions": { "project": "./tsconfig.json", "ecmaVersion": 2020 }, "rules": { // optional: override rules } } // tsconfig.json { "compilerOptions": { "strict": true, "noUnusedLocals": true // ... } }

Debug

Known issues

breakingPeer dependencies must be installed manually; missing them will cause ESLint errors.

fix

Run `npm install --save-dev @typescript-eslint/eslint-plugin eslint-plugin-sonarjs`

affects: >=1.0

gotchaRequires TypeScript strict mode in tsconfig.json; will produce false positives otherwise.

fix

Set `"strict": true` in compilerOptions

affects: >=1.0

deprecatedLegacy typestrict@1 for TSLint users; modern versions are ESLint-only.

fix

Use typestrict@latest with ESLint, or use typestrict@1 for TSLint.

affects: =1.0

gotchaConfig enforces `no-invalid-this` which can conflict with class property initializers in TypeScript.

fix

Override rule: `'no-invalid-this': 'off'` if needed.

affects: >=1.0

gotchaConfig uses `@typescript-eslint/no-floating-promises` which requires parserOptions.project to be set correctly.

fix

Ensure `parserOptions.project` points to your tsconfig.json.

affects: >=1.0

Errors

Common errors & fixes

ESLint: Error while loading rule '@typescript-eslint/await-thenable': You have used a rule which requires parserServices to be generated. You must provide the `parserOptions.project` property for @typescript-eslint/parser.

Missing parserOptions.project in ESLint config.

fix

Add `"parserOptions": { "project": "./tsconfig.json" }` to ESLint config.

ESLint: Cannot find module 'eslint-plugin-sonarjs'

Peer dependency not installed.

fix

Run `npm install --save-dev eslint-plugin-sonarjs`.

ESLint: Configuration for rule '@typescript-eslint/no-unnecessary-condition' is invalid: Value "true" is not a valid severity.

Incorrect rule severity format.

fix

Use `"warn"` or `"error"` instead of `true`.
