## Description
|
|
|
|
Basic bindings for [cheerio](https://cheerio.js.org/). Only includes read-only functionality for now.
|
|
|
|
## Installation
|
|
|
|
Install [cheerio](https://www.npmjs.com/package/cheerio) dependency:
|
|
|
|
$ npm install --save cheerio
|
|
|
|
Install this package:
|
|
|
|
* Using [bower](https://bower.io/):
|
|
|
|
$ bower install --save purescript-cheerio
|
|
|
|
* Using [psc-package](https://github.com/purescript/psc-package):
|
|
|
|
$ psc-package install cheerio
|
|
|
|
You might need to set up a [custom package set](https://github.com/purescript/psc-package#add-a-package-to-the-package-set).
|
|
|
|
## Example
|
|
|
|
From [basic example](examples/Basic.purs).
|
|
|
|
Imports:
|
|
|
|
import Cheerio (Cheerio, find, length)
|
|
import Cheerio.Static (loadRoot)
|
|
|
|
Example html:
|
|
|
|
htmlEx :: String
|
|
htmlEx = """
|
|
<ul id="fruits">
|
|
<li class="apple">Apple</li>
|
|
<li class="orange">Orange</li>
|
|
<li class="pear">Pear</li>
|
|
</ul>
|
|
"""
|
|
|
|
Load it and get the root element:
|
|
|
|
root :: Cheerio
|
|
root = loadRoot htmlEx
|
|
|
|
Use the query functions:
|
|
|
|
let fruitCount = find "#fruits" root # length
|
|
in log $ "Number of fruits: " <> show fruitCount
|
|
|
|
For more examples, please take a look at the [unit tests](test/Test/Main.purs). They cover most of the read-only cheerio functions.
