library0.12.0jsnpmunverified

CoffeeScript formatter/beautifier inspired by gofmt, version 0.12.0 (last released 2018, no recent updates). It formats CoffeeScript code with options for indent style and size. Differentiates via golang-like philosophy but limited adoption and potential bugs in edge cases. Supports CLI and JS API. Note: CoffeeScript itself is deprecated.

Code
Verified usage

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

default
✓ import fmt from 'coffee-fmt'
✗ const fmt = require('coffee-fmt')
Package supports CJS require; there is no default export for ESM.
format
✓ const { format } = require('coffee-fmt')
✗ import { format } from 'coffee-fmt'
No named export for ESM; use default import or CJS destructuring.
format
✓ const fmt = require('coffee-fmt'); fmt.format(code, opts)
✗ const format = require('coffee-fmt/format')
Wrong path; format is a method on the default export.

Reads CoffeeScript file, formats with 2-space indent, outputs to stdout.

const fmt = require('coffee-fmt'); const fs = require('fs'); const coffee = fs.readFileSync('example.coffee', 'utf8'); try { const formatted = fmt.format(coffee, { tab: ' ', newLine: '\n' }); console.log(formatted); } catch (e) { console.error('Formatting failed:', e.message); }
