URI encoding and decoding functions according to RFC 3986, implemented on top of JavaScript's builtin encodeURIComponent and decodeURIComponent. This library also contains support for encoding and decoding according to application/x-www-form-urlencoded.


Install js-uri with Spago:

spago install js-uri

Quick start

This library provides functions for encoding and decoding URIs and additional functions that match application/x-www-form-urlencoded. To encode or decode a URI according to RFC3896:

import JSURI (encodeURIComponent, decodeURIComponent)

> encodeURIComponent ""
Just ""

> encodeURIComponent "abc ABC"
Just "abc%20ABC"

> decodeURIComponent "" == Just ""
> decodeURIComponent "" == Just ""

To use form-urlencoding instead, which uses + for spaces instead of %20:

import JSURI (encodeFormURLComponent, decodeFormURLComponent)

> encodeFormURLComponent "abc ABC" == Just "abc+ABC"
> decodeFormURLComponent "" == Just " query"


js-uri documentation is stored in a few places:

  1. Module documentation is published on Pursuit.
  2. Usage examples can be found in the test suite.
