CloudExplorer2

CloudExplorer2

Manage your users’ cloud services from your application.

There is a live demo here

Install

$ npm install --save cloud-explorer

Use

Here is an example on how to use Cloud Explorer’s router to expose an API used by the front end to list files, read and write - see this file for a complete example

// before this create an express application

const CloudExplorer = require('cloud-explorer');

const router = new Router({
  dropbox: {
    clientId: '8lxz0i3aeztt0im',
    clientSecret: 'twhvu6ztqnefkh6',
    redirectUri: `${rootUrl}/ce/dropbox/oauth_callback`,
    state: 'abcd'
  },
  ftp: {redirectUri: `${rootUrl}/ce/ftp/signin`},
});

app.use('/ce', router);

There is also an example of use in Silex website builder here.

And here is an easy way to run a local ftp for tests: npx ftp-srv ftp://0.0.0.0:2121 --root .

Client side

For a complete example see the dist folder.

On the client side, the HTML:

<iframe id="ceIFrame" class="container" src="/ce/cloud-explorer/cloud-explorer.html" />

And the Javascript:

const ce = document.querySelector('#ceIFrame').contentWindow.ce;
ce.showThumbnails(true);
ce.openFile(['.jpg', '.jpeg', '.png', '.gif'])
.then(fileInfo => {
    if(fileInfo) alert('you chose:' + fileInfo.path);
    else alert('you canceled');
})
.catch(e => alert('an error occured: ' + e.message));

In order to know what are the possible options, please read the code

Server side config

When creating CE2 router, your app can pass it options, please see the example in lib/index.js. This is how you are supposed to enable or disable cloud services, or features.

Also you can add custom services and image banks, for this you can use the methods of the Router class: addService and addImageBank.

Notes:

• if you enable only one service, CE2 will be in “single service” mode and the user will not be presented the list of services but directly enters the only service (if logged in).

API

You can use only CE2 API, it makes Dropbox, FTP, SFTP, Webdav protocols accessible over HTTPS

Cookies or headers

Authentication uses cookie session or can be set from headers. The headers starting with UNIFILE_ are recognized and expected to be UNIFILE_{connector}_{key}_{value}, e.g. curl 'http://localhost:6805/ce/ftp/ls/' -H 'UNIFILE_FTP_HOST: localhost' -H 'UNIFILE_FTP_TOKEN: demo' -H 'UNIFILE_FTP_PORT: 21' -H 'UNIFILE_FTP_USER: demo'

WARNING: you need to allow underscores (_) in headers if you are using nginx or apache servers

Dev setup

To contribute to Cloud Explorer, clone this repo and build:

$ git clone github:silexlabs/CloudExplorer2
$ cd CloudExplorer2
$ npm i
$ npm run build

This will compile the JS files from src/ with ReactJS and Babel. The generated files will go in dist/.

You can serve dist on http://localhost:6805 with

$ npm start

And then access the demo app on http://localhost:6805/ce/cloud-explorer/

Docs

Please feel free to ask in the issues, and contribute docs in the wiki.

For now, the best way to know the API is to take a look at the App class which exposes all CE methods here.
