contxt-sdk

Installation

The contxt-sdk can be installed with NPM:

npm install --save @ndustrial/contxt-sdk

There are two peer dependencies for contxt-sdk, auth0-js and axios. If you don't already have a compatible version installed, run:

npm install --save auth0-js@^9.0.0 axios@~0.17.0

Getting Started

Once installed, the minimum configuration you need to get going is to include the clientId of your application (from Auth0) and a string with the type of authentication you want to use (auth0WebAuth or machineAuth).

import ContxtSdk from '@ndustrial/contxt-sdk';

const contxtSdk = new ContxtSdk({
  config: {
    auth: {
      clientId: 'example clientId from auth0'
    }
  },
  sessionType: 'auth0WebAuth'
});

contxtSdk.facilities.getAll().then((facilities) => {
  console.log(`all of my facilities: ${JSON.stringify(facilities)}`);
});

Information about using the auth0WebAuth and machineAuth modules is available in the API docs here (auth0WebAuth) and here (machineAuth). Additional information about configuration options can also be found in the API docs.

Adding in external modules

At times when building your application, there might be a Contxt API that you need to reach that is not currently included in the contxt-sdk package. To help out with this, we've created a way to include an external module into the SDK when creating an SDK instance that allows the external module to act as a first class extension of the SDK's API.

To do this, just include information about the module when creating your contxt-sdk instance:

import ContxtSdk from 'contxt-sdk';
import NewModule from './NewModule';

const contxtSdk = new ContxtSdk({
  config: {
    auth: {
      clientId: 'example clientId from auth0'
    }
  },
  externalModules: {
    newModule: {
      clientId: 'The Auth0 Id of the API you are communicated with',
      host: 'http://newModule.example.com',
      module: NewModule
    }
  },
  sessionType: 'auth0WebAuth'
});

contxtSdk.newModule.doWork();

When we decorate your external module into your SDK instance, it is treated just like one of the native, internal modules and is provided with the SDK instance (so you can use other parts of the SDK from your new module) and its own request module, which will handle API tokens if you are working with a Contxt API.

class NewModule {
  constructor(sdk, request) {
    this._baseUrl = `${sdk.config.audiences.newModule.host}/v1`;
    this._request = request;
    this._sdk = sdk;
  }

  doWork() {
    return this._request.patch(`${this._baseUrl}/data`, { work: 'finished' });
  }
}

export default NewModule;

Development

Building the package

rollup.js is used to build the source code into CommonJS and ES6 modules that can be used for distribution. These modules are both built by running one command: npm run build. If you'd like to continuously create builds as files are changed (i.e. if you are developing new features and have set things up correctly with npm link to serve the newly updated files to your app), you can run npm run watch.

Testing & Code Quality

Some important NPM tasks for running the test suite:

• npm test - Lints, sets up tracking for Istanbul coverage reports, and runs the test suite
• npm run test:js - Runs the test suite
• npm run test:js:dev - Runs the test suite in watch mode, where the tests are re-run whenever a file changes
• npm run test:js:inspect - Runs the test suite in inspect/inspect-brk mode. Insert a debugger somewhere in your code and connect to the debugger with this command. (Node 8: visit chrome://inspect to connect. Node 6: Copy and paste the blob provided in the terminal into Chrome to connect. Older versions also have ways to connect.)
• npm run lint - Lints the source code
• npm run coverage - Sets up tracking for Istanbul coverage reports and runs the test suite
• npm run report - Parses the Istanbul coverage reports and writes them to file (in ./coverage) and displays them in terminal

Some tools used for testing and ensuring code quality include:

• Chai.js (specifically the expect syntax)
• chai-as-promised
• ESLint
• eslint-config-ndustrial
• faker.js
• Mocha
• Sinon.JS
• sinon-chai

Additionally, some globals have been added to the testing environment to streamline the process slightly:

• expect - Corresponds with require('chai').expect. Info
• faker - Corresponds with require('faker'). Info
• sandbox - Corresponds with require('sinon').sandbox. Should be used anytime when wanting to create a sinon.spy or sinon.stub as it can be easily used to reset/restore multiple spys and stubs. Info

Changelog

v0.0.8 (2018-04-16)

Added

• Added some methods to help out when working with facility groupings. They are namespaced under facilities (i.e. facilities.groupings.methodName()) and include:
  • FacilityGroupings#addFacility to add a facility to a facility grouping
  • FacilityGroupings#create for creating new facility groupings
  • FacilityGroupings#getAll for getting a list of all facility groupings
  • FacilityGroupings#removeFacility to remove a facility from a facility grouping
