`
`js
const listWebms = require('4chan-list-webm')
// promise
listWebms('wsg', 2045456)
.then(data => console.log(data.webms))
.catch(err => console.error('404!', err))
// async/await
async function run () {
try {
const data = await listWebms('http://boards.4chan.org/wsg/thread/2045456')
console.log(data)
} catch (err) {
console.error('Whoa! 404! :c', err)
}
}
run()

#### CORS, and why this doesn't work in the browser
Because CORS is only supported with an origin of http(s)://boards.4chan.org,http(s)://boards.4chan.org
this module does not work in the browser; it only works with Node.js. The ONLY exception to this is if you're creating a Chrome plugin, with set as the origin.
#### Rate limits
As stated in the 4chan API, you must ensure that you do not make more than one request per second. It is __your__ responsiblity to ensure that the request limit is respected. I recommend using limiter or bottleneck.
#### Thumbnails
You will get an 403 Forbidden error if you try to load the thumbnails via inline linking (eg. changing the src attribute of an via JavaScript, or hard-coding it). You can still download these images via a proxy server and serve them there.
