jts-minify

library2.5.14jsnpmunverified

jts-minify v2.5.14 is a utility for minifying JavaScript and TypeScript files. It works as a CLI tool and a library, offering basic minification features like removing whitespace, comments, and optionally encoding output as base64. The package is stable with weekly downloads under 500, and has no notable alternatives in the npm ecosystem for combined JS/TS minification. Its key differentiator is the base64 encoding option, which is uncommon in minifiers.

Code

Verified usage

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

jtsMinify

✓ import { jtsMinify } from 'jts-minify'

✗ const jtsMinify = require('jts-minify')

ESM-only since v2.0; CommonJS require will fail.

minifyFile

✓ import { minifyFile } from 'jts-minify'

✗ import minifyFile from 'jts-minify'

This is a named export, not default.

minifyString

✓ import { minifyString } from 'jts-minify'

✗ import { minify } from 'jts-minify'

The function is named minifyString, not minify.

Shows how to minify strings and files, with and without base64 encoding option.

import { minifyString, minifyFile } from 'jts-minify'; // Minify a string const code = 'const x = 1; // comment'; const result = minifyString(code, { base64: false }); console.log(result); // "const x=1;" // Minify a file await minifyFile('input.js', 'output.min.js'); // With base64 encoding const encoded = minifyString(code, { base64: true }); console.log(encoded); // "Y29uc3QgeD0xOw=="

Debug

Known issues

breakingESM-only since v2.0; requires "type": "module" in package.json or .mjs extension.

fix

Switch to ES module import syntax and ensure project uses ESM.

affects: >=2.0.0

gotchaBase64 output includes a newline at the end of the encoded string, which may cause issues in some contexts.

fix

Trim the result: result.trim() or use replace(/\n$/, '').

affects: >=1.0.0

gotchaFile minification overwrites the output file without warning; there is no backup.

fix

Always specify a different output filename or manually back up the original.

affects: >=1.0.0

deprecatedThe option `minify` in options object is deprecated; use `minifyOptions` instead.

fix

Rename option to `minifyOptions`.

affects: >=2.5.0

Errors

Common errors & fixes

SyntaxError: Unexpected token 'export'

Trying to require() an ESM-only module with CommonJS require.

fix

Use import syntax or rename file to .mjs, or set "type": "module" in package.json.

TypeError: jtsMinify is not a function

Importing the module incorrectly, likely using default import for a named export.

fix

Use `import { jtsMinify } from 'jts-minify'` instead of `import jtsMinify from 'jts-minify'`.

Error: ENOENT: no such file or directory, open 'input.js'

The input file path is incorrect or the file doesn't exist.

fix

Ensure the input file path is correct and the file exists before calling minifyFile.
