uPort Core JS

Introduction | Quick Start | Modules | Development Guide

‼️ ⚠️ Transport modules rely on a spec change that is yet to be released in the uPort mobile app. Until the new mobile app is released, integrating the transport modules is not fully supported. Once it is fully supported, we will remove this message.

Introduction

For more information about uPort visit both uport.me and the developer docs site for more information on our platform and other libraries.

uport-core is a loosely coupled collection of functions and modules to use for building on and interacting with the uPort platform. If you are looking for quick start integration you will likely be better served by using both uport-connect and uport-js. But if you are looking for a deeper understanding or integration, customizing functionality for the other libraries or building your own libraries on the uPort platform, then you may want to use what is provided here. At this time uport-core-js mostly consists of transports, but may be home to other modules in the future.

For any questions or library support reach out to the uPort team on Riot or create a Github issue.

Quick Start

Install through npm:

npm install uport-core

Import specific modules:

import { transport, message, crypto } from 'uport-core'

Modules

Transport

Transports deal with sending messages to and from uPort clients, and generally setting up communication channels. Most often this involves sending messages to and from the uPort mobile app. At this time there are three primary transports:

• QR Codes: Messages are sent in a QR code to the mobile app client. You can use our default modal and flow here or configure your own QR codes. You can use our messaging server Chasqui to receive responses our have response returned to your own server.

• URL Passing: Messages are sent in a QR code to the mobile app client. You can use our default modal and flow here or configure your own QR codes. You can use our messaging server Chasqui to receive responses our have response returned to your own server.

• Push Notifications: Messages are sent in a QR code to the mobile app client. You can use our default modal and flow here or configure your own QR codes. You can use our messaging server Chasqui to receive responses our have response returned to your own server.

Beside the primary transports provided there is a number of smaller composable functions available to build your own transports for different needs. As we (and the community) build more transports for differing communication channels and differing uPort clients we will add them here.

Message

Only contains util functions at this time that help with adding params to request URIs. May contain other functions related to creating and parsing messages on our platform.

Crypto

Only contains encryptMessage() at this time, which is used for push notifications. May include a collection of other commonly used crypto functions in the future.

Development Guide

Run Locally

Download this repo or your fork, then run npm install.

Builds

All builds are created from files in /src

To transpile to ES5. All files are output to /lib. The entry of our npm package is /lib/index.js

$ npm run build:es5

To generate a bundle/distributable. We use webpack for our builds. The output dist is /dist/uport-core.js and source map /dist/uport-core.map.js

$ npm run build:dist

Tests

We write our tests using mocha, chai and sinon.

To run our tests:

$ npm run test
