fixmyjs

library2.0.0jsnpmunverified

fixmyjs automatically fixes JavaScript code based on lint rules from JSHint/JSLint. Version 2.0.0 is latest stable, with no active development since 2016. It applies transformations like adding curly braces, converting to strict equality, hoisting vars, and more. Unlike ESLint's --fix, it works as a separate CLI tool or library. Maintenance mode: critically depends on unmaintained JSHint.

Install & Compatibility

Where this runs

No compatibility data collected yet for this library.

Code

Verified usage

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

fix

✓ import { fix } from 'fixmyjs'

✗ const fix = require('fixmyjs')

ESM import is correct; CommonJS require gives a function, not an object.

default import

✓ import fixmyjs from 'fixmyjs'; const result = fixmyjs.fix(code, options);

✗ import { default as fixmyjs } from 'fixmyjs'

Default import gives an object with fix method.

TypeScript type

✓ import type { FixOptions } from 'fixmyjs'

✗ import { FixOptions } from 'fixmyjs'

Types are not shipped; use @types/fixmyjs or declare module.

Demonstrates programmatic usage: fixes code by converting == to === and ++ to +=1.

import { fix } from 'fixmyjs'; const code = 'var x = 1; if (x == 1) { x++; }'; const options = { eqeqeq: true, plusplus: true }; const fixed = fix(code, options); console.log(fixed); // 'var x = 1; if (x === 1) { x += 1; }'
