minify-ts

library1.3.1jsnpmunverified

A TypeScript code minifier leveraging the TypeScript compiler (v1.3.1, stable, quarterly releases) to safely rename variables, classes, functions, properties, and methods to short forms. Unlike general minifiers (e.g., terser), it fully understands TypeScript semantics and respects type safety, preserving exports and type declarations while achieving maximum compression. Key differentiators: AST-based renaming with no risk of breaking type inference, compatible with any TypeScript project, and produces valid JavaScript/TypeScript output.

Code

Verified usage

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

default

✓ import minifyTS from 'minify-ts'

✗ const minifyTS = require('minify-ts')

Package is ESM-only. CJS require will fail.

MinifyOptions

✓ import type { MinifyOptions } from 'minify-ts'

✗ import { MinifyOptions } from 'minify-ts'

Type-only import for TypeScript.

minify

✓ import { minify } from 'minify-ts'

✗ import minify from 'minify-ts'

Named export for the minify function.

Minifies a TypeScript string with mangling enabled, outputting as JavaScript. Writes result to file and prints size.

import { minify } from 'minify-ts'; import { writeFileSync } from 'fs'; const code = ` interface User { name: string; age: number; } const user: User = { name: 'Alice', age: 30 }; function greet(user: User): string { return `Hello, ${user.name}!`; } console.log(greet(user)); `; const result = minify(code, { mangle: true, compress: false, output: 'js', }); writeFileSync('output.js', result.code); console.log('Minified size:', result.map ? 'N/A' : result.code.length);

Debug

Known issues

breakingRemoved support for Node 12 in v1.3.0

fix

Use Node 14+ or stay on v1.2.x

affects: >=1.3.0

deprecatedOptions 'compress' and 'sourcemap' deprecated in favor of 'minify' and 'map'

fix

Replace 'compress: true' with 'mangle: true' and use 'map: true' instead of 'sourcemap: true'

affects: >=1.3.0

gotchaInput must be valid TypeScript; invalid syntax causes silent failure

fix

Run tsc --noEmit before minifying to catch syntax errors

affects: *

Errors

Common errors & fixes

TypeError: minify_ts_1.default is not a function

Using CommonJS require with ESM-only package

fix

Switch to ES import: import minifyTS from 'minify-ts'

Error: Cannot find module 'minify-ts'

Package not installed or path incorrect

fix

Run npm install minify-ts

SyntaxError: Unexpected token : (or other TS-specific syntax)

Input contains TypeScript syntax but output is set to 'js' without proper handling

fix

Ensure all TypeScript syntax is valid and set output to 'ts' if preserving types
