html-generators

library1.1.0jsnpmunverified

A library for generating random HTML strings for property-based testing. Version 1.1.0 is stable with no recent releases (last updated 2017). It builds on chance-generators and integrates with unexpected-check and unchecked. Unlike other HTML generators, it produces structurally valid but semantically random HTML documents, including elements, attributes, and content. Supports custom seeds and limits. Suitable for testing HTML parsers, minifiers, sanitizers, and other tools where diverse HTML input is needed.

Code

Verified usage

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

htmlString

✓ const { htmlString } = require('html-generators')

✗ const htmlString = require('html-generators')

htmlString is a named export, not a default export

htmlFragment

✓ const { htmlFragment } = require('html-generators')

✗ import { htmlFragment } from 'html-generators'

Package uses CommonJS, not ESM. ESM import will fail without bundler

htmlDocument

✓ const { htmlDocument } = require('html-generators')

✗ const htmlDocument = require('html-generators').htmlDocument

Destructuring is preferred but property access also works

Demonstrates generating random HTML strings, fragments, and documents using the three main generators.

const { htmlString, htmlFragment, htmlDocument } = require('html-generators'); const seed = Date.now(); const generator = htmlString({ seed }); console.log(generator.first()); // Output: random HTML string const fragGenerator = htmlFragment({ seed: seed + 1 }); console.log(fragGenerator.first()); const docGenerator = htmlDocument({ seed: seed + 2 }); console.log(docGenerator.first());

Known issues

deprecatedThe library is in maintenance mode with no updates since 2017.

fix

Consider migrating to a more modern alternative like faker or quick-check.

affects: >=1.0.0

gotchaGenerated HTML may contain invalid attribute values or malformed content.

fix

Do not use for production HTML generation; intended for testing with property-based testing frameworks.

affects: >=1.0.0

breakingCommonJS only – ESM imports will throw 'ERR_REQUIRE_ESM'.

fix

Use require() instead of import, or use a bundler.

affects: >=1.0.0

Errors

Common errors & fixes

Cannot find module 'html-generators'

npm package not installed or misspelled

fix

Run 'npm install html-generators' and ensure it is in package.json dependencies.

htmlString is not a function

Used wrong import style – destructing missing or used default import

fix

Use 'const { htmlString } = require('html-generators')'

TypeError: htmlString.first is not a function

htmlString is a factory, not a direct iterator. Must call .first() on the generator instance

fix

Assign result: 'const gen = htmlString(); const result = gen.first();'
