feathers-unsplash

FeathersJS service adapter for the Unsplash API

About

This project uses Feathers. An open source web framework for building modern real-time applications.

Currently only the UnsplashPhotos service class is supported.

Install

npm install feathers-unsplash node-fetch

yarn add feathers-unsplash node-fetch

This adapter requires fetch support, which means you'll need to provide it on the global scope. This means that somewhere in your app you need to use this code:

const fetch = require('node-fetch')
global.fetch = fetch

Setup API Access

First you'll need to setup Unsplash API access.

  1. Create an app on the Unsplash API
  2. Copy the accessKey into an environment variable.
  3. Setup the FeathersJS config
// default.json

"unsplash": {
    "accessKey": "MYAPPNAME_UNSPLASH_ACCESS_KEY"
}

Setup a Service

The easiest way to setup a service is to use the FeathersJS Cli to generate a "Custom Service". You can then delete the service-name.class.js file that the generator makes and use code like in this example:

// Initializes the `unsplash-photos` service on path `/unsplash-photos`
const { UnsplashPhotos } = require('feathers-unsplash')
const hooks = require('./unsplash-photos.hooks')

const fetch = require('node-fetch')
global.fetch = fetch


module.exports = function (app) {
  const options = {
    accessKey: app.get('unsplash').accessKey
  }

  // Initialize the service with any options it requires
  app.use('/unsplash-photos', new UnsplashPhotos(options, app))

  // Get the initialized service so that we can register hooks
  const service = app.service('unsplash-photos')

  service.hooks(hooks)
}

API

find

The find method supports searching photos by the following query params:

  • keyword: the search text
  • orientation: can be either portrait or landscape. Any other values return an empty list.
  • collections: an array of collection ids.

It also supports familiar pagination attributes: $limit and $skip. Note that since the Unsplash API only supports page-level pagination (not record-level skipping like most FeathersJS adapters), you must provide $skip as a multiple of the $limit. Here is an example query:

const response = await app.service('unsplash-photos').find({
  query: {
    keyword: 'food',
    orientation: 'portrait',
    $limit: 10, // this is the default limit
    $skip: 10 // Skipping 10 returns the second page of data.
  }
})

get

The get method can be used in two ways:

  • Pass an image id to retrieve data about the image.
  • Pass 'random' to retrieve a random image.
const imageData = await app.service('unsplash-photos').get(id)
const randomImg = await app.service('unsplash-photos').get('random')

Testing & Debugging

Run npm test to run all tests in the test/ directory.

A debug configuration is also included for Visual Studio Code. This means you can debug with breakpoints by opening the project in VSCode and running the "Mocha Tests" script.
