  7. An HTTP content negotiator for Node.js
  8. ## Installation
  9. ```sh
  10. $ npm install negotiator
  11. ```
  12. ## API
  13. ```js
  14. var Negotiator = require('negotiator')
  15. ```
  16. ### Accept Negotiation
  17. ```js
  18. availableMediaTypes = ['text/html', 'text/plain', 'application/json']
  19. // The negotiator constructor receives a request object
  20. negotiator = new Negotiator(request)
  21. // Let's say Accept header is 'text/html, application/*;q=0.2, image/jpeg;q=0.8'
  22. negotiator.mediaTypes()
  23. // -> ['text/html', 'image/jpeg', 'application/*']
  24. negotiator.mediaTypes(availableMediaTypes)
  25. // -> ['text/html', 'application/json']
  26. negotiator.mediaType(availableMediaTypes)
  27. // -> 'text/html'
  28. ```
  29. You can check a working example at `examples/accept.js`.
  30. #### Methods
  31. ##### mediaType()
  32. Returns the most preferred media type from the client.
  33. ##### mediaType(availableMediaType)
  34. Returns the most preferred media type from a list of available media types.
  35. ##### mediaTypes()
  36. Returns an array of preferred media types ordered by the client preference.
  37. ##### mediaTypes(availableMediaTypes)
  38. Returns an array of preferred media types ordered by priority from a list of
  39. available media types.
  40. ### Accept-Language Negotiation
  41. ```js
  42. negotiator = new Negotiator(request)
  43. availableLanguages = ['en', 'es', 'fr']
  44. // Let's say Accept-Language header is 'en;q=0.8, es, pt'
  45. negotiator.languages()
  46. // -> ['es', 'pt', 'en']
  47. negotiator.languages(availableLanguages)
  48. // -> ['es', 'en']
  49. language = negotiator.language(availableLanguages)
  50. // -> 'es'
  51. ```
  52. You can check a working example at `examples/language.js`.
  53. #### Methods
  54. ##### language()
  55. Returns the most preferred language from the client.
  56. ##### language(availableLanguages)
  57. Returns the most preferred language from a list of available languages.
  58. ##### languages()
  59. Returns an array of preferred languages ordered by the client preference.
  60. ##### languages(availableLanguages)

  65. availableCharsets = ['utf-8', 'iso-8859-1', 'iso-8859-5']
  66. negotiator = new Negotiator(request)
  67. // Let's say Accept-Charset header is 'utf-8, iso-8859-1;q=0.8, utf-7;q=0.2'
  68. negotiator.charsets()
  69. // -> ['utf-8', 'iso-8859-1', 'utf-7']
  70. negotiator.charsets(availableCharsets)
  71. // -> ['utf-8', 'iso-8859-1']
  72. negotiator.charset(availableCharsets)
  73. // -> 'utf-8'
  74. ```
  75. You can check a working example at `examples/charset.js`.
  76. #### Methods
  77. ##### charset()
  78. Returns the most preferred charset from the client.
  79. ##### charset(availableCharsets)
  80. Returns the most preferred charset from a list of available charsets.

  91. negotiator.encodings()
  92. // -> ['gzip', 'identity', 'compress']
  93. negotiator.encodings(availableEncodings)
  94. // -> ['gzip', 'identity']
  95. negotiator.encoding(availableEncodings)
  96. // -> 'gzip'
  97. ```
