Minor Changes

• BREAKING CHANGE: Removed Headers/SuperHeaders class and default export. Use the native Headers class with the static from() method on each header class instead.

  New individual header .from() methods:

  • Accept.from()
  • AcceptEncoding.from()
  • AcceptLanguage.from()
  • CacheControl.from()
  • ContentDisposition.from()
  • ContentRange.from()
  • ContentType.from()
  • Cookie.from()
  • IfMatch.from()
  • IfNoneMatch.from()
  • IfRange.from()
  • Range.from()
  • SetCookie.from()
  • Vary.from()

  New raw header utilities added:

  • parse()
  • stringify()

  Migration example:

  // Before:
  import SuperHeaders from '@remix-run/headers'
  let headers = new SuperHeaders(request.headers)
  let mediaType = headers.contentType.mediaType
  
  // After:
  import { ContentType } from '@remix-run/headers'
  let contentType = ContentType.from(request.headers.get('content-type'))
  let mediaType = contentType.mediaType

  If you were using the Headers constructor to parse raw HTTP header strings, use parse() instead:

  // Before:
  import SuperHeaders from '@remix-run/headers'
  let headers = new SuperHeaders('Content-Type: text/html\r\nCache-Control: no-cache')
  
  // After:
  import { parse } from '@remix-run/headers'
  let headers = parse('Content-Type: text/html\r\nCache-Control: no-cache')

  If you were using headers.toString() to convert headers to raw format, use stringify() instead:

  // Before:
  import SuperHeaders from '@remix-run/headers'
  let headers = new SuperHeaders()
  headers.set('Content-Type', 'text/html')
  let rawHeaders = headers.toString()
  
  // After:
  import { stringify } from '@remix-run/headers'
  let headers = new Headers()
  headers.set('Content-Type', 'text/html')
  let rawHeaders = stringify(headers)
