mixcloud-fetch

A JS library for fetching Mixcloud resources.

Note: this library does not support user logins, so you won't be able to fetch exclusive content or access account-specific features.

Installation

npm i mixcloud-fetch --save

Usage

const mcfetch = require('mixcloud-fetch');

mcfetch.tag(['ambient', 'lounge']).getShows().then( shows => {
    ...
});

mcfetch.search('jazz funk').getTags().then( tags => {
    ...
});

Tag functions

A tag is used to discover shows and is identified by its slug. To access tag-related functions, you need to obtain a Tag object with the slug.

const slug = 'jazz';
const tag = mcfetch.tag(slug);

// Fetch shows matching the 'jazz' tag
tag.getShows().then( shows => {
    ...
});

You can encapsulate multiple tags in a Tag object by putting their slugs into an array:

const slugs = [
    'jazz',
    'funk'
];
const tag = mcfetch.tag(slugs);

// Fetch shows matching both the 'jazz' and 'funk' tags
tag.getShows().then( shows => {
    ...
});

The following functions are provided by a Tag object. Each of these functions returns a Promise that resolves to the data requested.

Function	Resolves To
getInfo()	Information about the represented tag(s)	Example (output)
getShows([params])*	Cloudcasts matching the represented tag(s)	Example (output)
getFeatured([params])*	Featured cloudcasts matching the represented tag(s)	Example (output)

*params specify what to return in the results. Check the example for what params you can specify.

User functions

A user is identified by his or her username. To access user-related functions, you need to obtain a User object with the username.

const username = 'jazzcat';
const user = mcfetch.user(username);

// Fetch shows uploaded by the user
user.getShows().then( shows => {
    ...
});

The following functions are provided by a User object. Each of these functions returns a Promise that resolves to the data requested.

Function	Resolves To
getInfo()	Information about the user	Example (output)
getShows([params])*	Cloudcasts uploaded by the user	Example (output)
getPlaylists()	Playlists owned by the user	Example (output)

*params specify what to return in the results. Check the example for what params you can specify.

Playlist functions

A playlist is identified by its ID. To access playlist-related functions, you need to obtain a Playlist object with the playlist's ID.

const playlistId = 'UGxheWxpc3Q6MTM5NDM2MA==';
const playlist = mcfetch.playlist(playlistId);

// Fetch shows in the playlist
playlist.getShows().then( shows => {
    ...
});

The following functions are provided by a Playlist object. Each of these functions returns a Promise that resolves to the data requested.

Function	Resolves To
getInfo()	Information about the playlist	Example (output)
getShows([params])*	Cloudcasts in the playlist	Example (output)

*params specify what to return in the results. Check the example for what params you can specify.

Cloudcast functions

A cloudcast is identified by its ID. To access cloudcast-related functions, you need to obtain a Cloudcast object with the cloudcast's ID.

const cloudcastId = 'Q2xvdWRjYXN0OjE1MDg0MzQzNA==';
const cloudcast = mcfetch.cloudcast(cloudcastId);

// Fetch info about the cloudcast
cloudcast.getInfo().then( info => {
    ...
});

There is only one function provided by a Cloudcast object:

Function	Resolves To
getInfo()	Information about the cloudcast	Example (output)

Search functions

The library supports searching Tags, Shows and Users. To access the search functions, you need to obtain a Search object with the keywords to search for.

const keywords = 'ambient lounge';
const search = mcfetch.search(keywords);

// Fetch shows matching 'ambient lounge':
search.getShows().then( shows => {
    ...
});

The following functions are provided by a Search object. Each of these functions returns a Promise that resolves to the data requested.

Function	Resolves To
getTags([params])	Tags matching the given keywords	Example (output)
getShows([params])	Cloudcasts matching the given keywords	Example (output)
getUsers([params])	Users matching the given keywords	Example (output)

params specify what to return in the results. Check the example for what params you can specify.

Miscellaneous functions

// Get Mixcloud categories
mcfetch.misc.getCategories().then( categories => {
    ...
});

// Get the list of available countries as well as the default
mcfetch.misc.getCountries().then( countries => {
    ...
});

Function	Resolves To
getCategories()	Mixcloud categories	Example (output)
getCountries()	Available countries and the default	Example (output)

Rate Limiting

Fetch requests are rate limited by default. Rate limiting is useful when you need to make a large number of queries and don't want to run the risk of getting rejected by the server for making too many requests within a short time interval.

The library uses Bottleneck for rate limiting. You can configure the rate limiter like this:

mcfetch.limiter.setOptions({
    maxConcurrent: 10,  // default: 5
    minTime: 100        // default: 200
});

setOptions() is just a passthrough function to Bottleneck's updateSettings(). Check the Bottleneck doc for the list of options you can set.

To check if the rate limiter is enabled:

mcfetch.limiter.isEnabled()

To disable the rate limiter:

mcfetch.limiter.setEnabled(false);

Caching

The library maintains an in-memory cache for storing results of fetch requests. You can access the cache functions as follows:

// Set the expiry time of cache entries (seconds)
mcfetch.cache.setTTL(500); // Default: 300

// Set the maximum number of entries that can be stored in the cache
// Specify a negative value (e.g -1) for unlimited entries.
mcfetch.cache.setMaxEntries(20); // Default: 10

// Clears the cache
mcfetch.cache.clear();

Changelog
