transpilify

2.0.3 verified Fri May 01 auth: no javascript

applies browserify transforms to source code without bundling, enabling bundler-agnostic npm distributions. Current stable version 2.0.3, experimental status. Useful for pre-applying transforms like glslify or brfs to individual files. Differentiates from full bundlers by emitting single-file transforms suitable for library authors. Low maintenance cadence; last release in 2018.

Common errors

error Error: Cannot find module 'brfs' ↓

cause Transform not installed locally or globally.

fix

npm install brfs --save-dev in project root.

error TypeError: createTranspiler is not a function ↓

cause Wrong import method; package exports are not default.

fix

Use const { createTranspiler } = require('transpilify') or import { createTranspiler } from 'transpilify'.

Warnings

deprecated stability experimental; last updated 2018. Future Node versions may break. ↓

fix Consider alternatives like babel or esbuild for active support.

gotcha Transforms that depend on bundler internals (like globals) will not work. ↓

fix Ensure transforms are purely source-to-source without bundler assumptions.

gotcha CLI --transform options use browserify subarg syntax; incorrect quoting can fail. ↓

fix Use proper shell escaping, e.g. -t [ babelify --presets [ es2015 ] ]

Install

npm install transpilify

yarn add transpilify

pnpm add transpilify

Imports

createTranspiler
wrong
```
const createTranspiler = require('transpilify')
```
correct
```
import { createTranspiler } from 'transpilify'
```
ESM default export not documented; require works but may not be type-safe. Use default import: import transpilify from 'transpilify' then call transpilify.createTranspiler() if needed.
default
wrong
```
const transpilify = require('transpilify').default
```
correct
```
import transpilify from 'transpilify'
```
The package has no named default export; require returns an object with createTranspiler.

createTranspiler

wrong

const createTranspiler = require('transpilify')

correct

const { createTranspiler } = require('transpilify')

require returns an object; destructure or use .createTranspiler.

Quickstart

Shows programmatic usage: create transpiler with brfs transform, pipe a file through, and write output.

import { createTranspiler } from 'transpilify';
import { readFileSync, writeFileSync } from 'fs';

const transpiler = createTranspiler({
  transform: ['brfs'],
  basedir: process.cwd()
});

let result = '';
transpiler('input.js')
  .on('data', chunk => result += chunk)
  .on('end', () => writeFileSync('output.js', result));

// CLI equivalent: transpilify input.js --transform brfs > output.js
