dts-minify-lite

library0.5.6jsnpmunverified

A lightweight zero-dependency minifier for TypeScript declaration files (.d.ts). Version 0.5.6 (maintained, active development on GitHub). It reduces file size by removing whitespace, comments, and shortening identifiers in declaration files. Unlike alternatives like dts-minify, it has no runtime dependencies and focuses purely on minification without transforming code.

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.

minify

✓ import { minify } from 'dts-minify-lite'

✗ import minify from 'dts-minify-lite'

ESM only; function is a named export, not default.

MinifyOptions

✓ import type { MinifyOptions } from 'dts-minify-lite'

✗ const { MinifyOptions } = require('dts-minify-lite')

Type import for TypeScript users; not a runtime export in CJS.

MinifyResult

✓ import type { MinifyResult } from 'dts-minify-lite'

✗ const MinifyResult = require('dts-minify-lite').MinifyResult

Type import, not a value. Available from v0.5.0+.

Reads a .d.ts file, minifies its content, and writes the output to a new file.

import { minify } from 'dts-minify-lite'; import { readFileSync, writeFileSync } from 'fs'; const dtsContent = readFileSync('types.d.ts', 'utf8'); const result = minify(dtsContent); writeFileSync('types.min.d.ts', result.code); console.log('Minified!', result);

Debug

Known issues

breakingIn v0.4.0, the return type of minify changed from string to object with 'code' and 'map' properties.

fix

Access result.code instead of using result directly as a string.

affects: >=0.4.0

gotchaInput must be valid TypeScript declaration syntax; malformed d.ts may cause runtime errors or incorrect output.

fix

Validate d.ts content before minifying.

affects: >=0.1.0

deprecatedSince v0.5.0, 'MinifyOptions' type has some options removed (e.g., 'keepComments'), use 'removeComments' and 'minifyIdentifiers'.

fix

Update configuration to use 'removeComments' and 'minifyIdentifiers'.

affects: >=0.5.0

gotchaMinification may rename identifiers that are referenced in external code, causing broken imports.

fix

Set 'minifyIdentifiers' to false unless you control all code consuming the d.ts.

affects: >=0.1.0

Errors

Common errors & fixes

TypeError: minify is not a function

Using default import instead of named import.

fix

Use import { minify } from 'dts-minify-lite'

Cannot read property 'code' of undefined

Using result directly as string from older version.

fix

Update to v0.4.0+ and access result.code

SyntaxError: Unexpected token

Input d.ts contains invalid or non-TypeScript syntax.

fix

Ensure input is valid .d.ts file, possibly pre-parse with TypeScript compiler.
