Verified usage

default

✓ import format from 'http-content-range-format'

✗ const { format } = require('http-content-range-format')

default (CommonJS)

✓ const format = require('http-content-range-format')

✗ const { format } = require('http-content-range-format')

Demonstrates formatting Content-Range headers with different range types: first-last, suffix, and unsatisfied.

import format from 'http-content-range-format'; // Format a Content-Range header for bytes 0-499/1234 const header = format({ first: 0, last: 499, length: 1234 }); console.log(header); // 'bytes 0-499/1234' // Format a suffix range (last N bytes) const suffixHeader = format({ length: 100, last: 99, total: 1000 }); console.log(suffixHeader); // 'bytes -99/1000' // Format an unsatisfied range (length only) const unsatisfiedHeader = format({ length: 0, total: 500 }); console.log(unsatisfiedHeader); // 'bytes */500'

Debug

Known issues

gotchaThe library expects object properties 'first', 'last', 'length', and 'total' exactly as documented; missing required fields will cause errors.

fix

Ensure all required fields are provided: for a standard range, include 'first' and 'last'; for suffix range, include 'length' and 'last'; for unsatisfied, include 'length' (or 'total' without 'first'/'last').

affects: >=1.0.0

gotchaThe 'total' field must be provided for a complete range; if omitted, the header will use '*' for total length.

fix

Provide 'total' when the total size is known; otherwise, it's optional.

affects: >=1.0.0

Errors

Common errors & fixes

TypeError: Cannot read property 'first' of undefined

Calling format() without arguments or with undefined/null.

fix

Pass an object with required properties: format({ first: 0, last: 499, length: 1234 })

TypeError: format is not a function

Incorrect import (e.g., destructuring default export in CommonJS).

fix

Use default import: const format = require('http-content-range-format')
