durable-json-lint

0.0.3 verified Fri May 01 auth: no javascript abandoned

A Json Lint library (v0.0.3, last updated in 2012) that parses and partially corrects dirty JSON without crashing. It can fix common errors like single quotes, hex numbers, and function calls, and returns corrected JSON alongside error details. Unlike most JSON linters, it continues parsing after errors and substitutes invalid constructs with null. Written in CoffeeScript, runs on Node >=0.4.0 and browsers. Low release cadence and minimal maintenance since 2013.

Common errors

error Error: Cannot find module 'coffee-script' ↓

cause Package's require may attempt to load CoffeeScript at runtime.

fix

Install coffee-script: npm install coffee-script

error TypeError: durableJsonLint is not a function ↓

cause Incorrect import: using named import instead of default.

fix

Use import durableJsonLint from 'durable-json-lint' or const durableJsonLint = require('durable-json-lint')

error Uncaught ReferenceError: require is not defined ↓

cause Using CommonJS require in ESM environment without bundler.

fix

Use import syntax or a bundler like webpack.

Warnings

deprecated Package is largely unmaintained since 2013; may not work with modern Node versions beyond 0.4.x. ↓

fix Consider using a maintained JSON linter like jsonlint or ajv.

gotcha Error status 'crash' indicates parser completely failed; no JSON returned. ↓

fix Wrap call in try-catch to handle crashes; check result.json for null.

gotcha The library substitutes invalid constructs with null without warning in corrected output. ↓

fix Always inspect errors array to understand substitutions.

breaking Package uses CoffeeScript; Node.js may require a CoffeeScript runtime to require if compiled .js missing. ↓

fix Use npm 1.x or precompile; on modern Node, install coffee-script globally or use an alternative.

gotcha Error descriptions may be humorous or sarcastic, not suitable for production error messages. ↓

fix Do not present user-facing errors directly.

Install

npm install durable-json-lint

yarn add durable-json-lint

pnpm add durable-json-lint

Imports

default

wrong

const durableJsonLint = require('durable-json-lint')

correct

import durableJsonLint from 'durable-json-lint'

Package does not specify ESM; CommonJS require works, but ESM import is more modern.

default

wrong

import { durableJsonLint } from 'durable-json-lint'

correct

const durableJsonLint = require('durable-json-lint')

Only default export; named import will fail.

TypeScript types

wrong

No type definitions exist

correct

import durableJsonLint from 'durable-json-lint' // then declare type manually

Package has no TypeScript types; use @types/durable-json-lint or define own.

Quickstart

Demonstrates linting dirty JSON with single quotes, function call, hex number and viewing corrected output and errors.

import durableJsonLint from 'durable-json-lint';

const result = durableJsonLint(`{name:"value", 'array':[call(), 0x11]}`);
console.log('Corrected JSON:', result.json);
console.log('Errors:', JSON.stringify(result.errors, null, 2));
