library0.0.3jsnpmunverified

Constructuring is an ES6-to-ES3 transpiler specifically for the destructuring feature. It transforms JavaScript code using ES6 destructuring (arrays and objects) into ES3-compatible code that runs in older browsers. Current version 0.0.3, with no recent updates indicating it is no longer maintained. It operates on source strings or esprima ASTs, making it suitable for integration into build pipelines that already use esprima and escodegen. Compared to broader transpilers like Babel, Constructuring focuses only on destructuring, which may be useful for targeted transformations but lacks active development and broader language feature support.

Code

Verified usage

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

transformSource

✓ const { transformSource } = require('constructuring');

✗ import { transformSource } from 'constructuring';

Package is CommonJS-only; no ESM exports available.

transform

✓ const { transform } = require('constructuring');

✗ const transform = require('constructuring').transform;

Alternative correct import for AST-based usage.

default

✓ const constructuring = require('constructuring');

✗ import constructuring from 'constructuring';

Default export is the module itself, but named exports are preferred.

Shows both source transformation and AST-based transformation using constructuring.

const { transformSource } = require('constructuring'); const fs = require('fs'); const source = fs.readFileSync('module.js', 'utf8'); const result = transformSource(source); console.log(result); // Also AST-based: const esprima = require('esprima'); const escodegen = require('escodegen'); const ast = esprima.parse(source); const { transform } = require('constructuring'); transform(ast); console.log(escodegen.generate(ast));

Debug

Known issues

deprecatedPackage is abandoned; last version 0.0.3 released years ago. No support for modern JavaScript or ES6 beyond destructuring.

fix

Use a modern transpiler like Babel or SWC for full ES6+ support.

affects: >=0.0.0

gotchaPackage is CommonJS-only; will not work with ESM imports without a bundler or wrapper.

fix

Use require() or wrap in a bundler that supports CJS.

affects: >=0.0.0

gotchaTransform functions mutate the AST if provided; ensure you have a copy if needed.

fix

Clone the AST before passing if you need the original for other purposes.

affects: >=0.0.0

breakingNo official TypeScript definitions; any type safety must be manually added.

fix

Create your own .d.ts or use @ts-ignore.

affects: >=0.0.0

deprecatedNo security patches or updates; known vulnerabilities in dependencies (esprima, escodegen) may be present.

fix

Do not use in production; fork and update dependencies if necessary.

affects: >=0.0.0

Errors

Common errors & fixes

TypeError: transformSource is not a function

Incorrect import: using default import instead of named import in CommonJS.

fix

Use const { transformSource } = require('constructuring');

SyntaxError: Unexpected token =

Source code contains ES6 syntax beyond destructuring (e.g., arrow functions) which constructuring cannot handle.

fix

First transpile with a broader tool like Babel, or ensure input only uses destructuring.

Module not found: Can't resolve 'constructuring'

Package is not installed or name is misspelled.

fix

Run npm install constructuring --save or check spelling: 'constructuring' (note: not 'constructuring').

Error: Cannot find module 'esprima'

When using AST mode, esprima and escodegen must be installed separately.

fix

npm install esprima escodegen
