SAFE-js

Isomorphic adaptation of API hooks found in the safe demo app.

Built using isomorphic-fetch, to work in node or in the browser.

Currently still in beta. YMMV. Please report any issues. Pull requests are entirely welcome for features and documentation.

Use

Grab it

npm i safe-js --save

And use it

import * as safe from 'safe-js';

Available methods are taken from the demo app, and docs (which are currently not up to date) live here: https://maidsafe.readme.io/docs/introduction .

safe.nfs safe.dns safe.auth structuredData appendableData dataId cipherOpts signKey

are objects available for use.

Alternatively you can access these same methods in the [Safe Beaker Browser (SBB)] (https://github.com/joshuef/beaker/), via window.safeAuth, window.safeNFS and window.DNS;

Polyfill

safe-js has a polyfill to create window.safeXXX functionality when it's not available (non safe:// sites in SAFE Beaker Browser, for eg. ).

You can simply include this file in the <head> of your page during development and continue using the APIs as they are provided by Safe Beaker Browser.

<head>
  <title>safejs site not yet on the network!</title>
  <!-- replace this link with the actual polyfill location -->
  <script src="./safe-js/dist/polyfill.js" ></script>            
</head>

Examples

Auth (window.safeAuth methods in the SAFE browser):

import { auth } from 'safe-js';
import packageData from '../package.json'

const LOCAL_STORAGE_TOKEN_KEY = 'BOOM';

const app =
{
    name: "name",
    id: "id",
    version: "v",
    vendor: "vendor_name",
    permissions: ["SAFE_DRIVE_ACCESS"]
};

auth.authorise( app );

getFile:

import { nfs } from 'safe-js';
nfs.createFile(token, 'primaryIndex.json', {} ,false, APP_DIR);

API

auth.js

(window.safeAuth methods in the SAFE browser)

TODO

  • NFS needs move endpoints

Todo

  • Add auth.js documentation.
  • Add dns.js documentation.
  • Add nfs.js documentation.
  • Improve documentation (clarity/readability/gitbook?).
  • Increase test coverage.
  • Ensure all API endpoints are represented.
  • Update isPathShared to appOrDrive ? ... Something more semantic.
