durable-json-lint

library0.0.3jsnpmunverified

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.

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.

default

✓ import durableJsonLint from 'durable-json-lint'

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

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

default

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

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

Only default export; named import will fail.

TypeScript types

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

✗ No type definitions exist

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

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));

Debug

Known issues

deprecatedPackage 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.

affects: >=0.0.3

gotchaError status 'crash' indicates parser completely failed; no JSON returned.

fix

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

affects: >=0.0.1

gotchaThe library substitutes invalid constructs with null without warning in corrected output.

fix

Always inspect errors array to understand substitutions.

affects: >=0.0.1

breakingPackage 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.

affects: >=0.0.1

gotchaError descriptions may be humorous or sarcastic, not suitable for production error messages.

fix

Do not present user-facing errors directly.

affects: >=0.0.1

Errors

Common errors & fixes

Error: Cannot find module 'coffee-script'

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

fix

Install coffee-script: npm install coffee-script

TypeError: durableJsonLint is not a function

Incorrect import: using named import instead of default.

fix

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

Uncaught ReferenceError: require is not defined

Using CommonJS require in ESM environment without bundler.

fix

Use import syntax or a bundler like webpack.
