bima-shark-sdk (Javascript)

This is the Javascript SDK for the BImA applications.

Installation

1. Install the npm package

npm install bima-shark-sdk

2. Bring your own fetch library.

• for browsers use whatwg-fetch as polyfill for Internet Explorer
• in AWS Lambda functions use node-fetch

3. In browser you have to use babel-loader to support IE 11 and project-wide babel.config.js. A .babelrc configuration is not enough and will ignore node_modules.

  // webpack.config.js
    module: {
      rules: [
        {
          test: /\.js$/,
          include: [
            path.resolve(__dirname, 'src'),
            path.resolve(__dirname, 'node_modules/bima-shark-sdk')
          ],
          use: {
            loader: 'babel-loader'
          }
        },
        ...

Usage

In browser

import Shark from 'bima-shark-sdk'

Shark.configure({
  debug: false,             // log request and response, when true
  secret: 'random-id',      // user specific secret e.g. id
  serviceTokenUrl: '/doorkeeper/service_token'
})

import { UserClient } from 'bima-shark-sdk'

const client = new UserClient('https://doorkeeper-development.bundesimmo.de')
client.find(123)
  .then(
    json => { console.log('Success: ', json) },
    err => { console.log('Error: ', err) }
  ).finally(
    () => { console.log('Hide loader') }
  )

In Node.js

const { MailingClient } = require('bima-shark-sdk')

const client = new MailingClient('https://mailing-development.bundesimmo.de', {
  serviceToken: {
    baseUrl: 'https://doorkeeper-development.bundesimmo.de',
    accessKey: 'your-access-key',
    secretKey: 'your-secret-key',
    userId: '1234567890'  // optional
  }
})

try {
  const json = await client.create({ foo: 'bar' })
  console.log('Success: ', json)
} catch (err) {
  console.log('Error: ', err)
}

Additionally, you can use your own function to generate authentication tokens:

const { MailingClient } = require('bima-shark-sdk')

const client = new MailingClient('https://mailing-development.bundesimmo.de', {
  getAuthToken: () => 'Bearer ' + crypto.randomBytes(20).toString('hex')
})

or generate JWT-based short-lived tokens which are valid for 1 minute:

const { MailingClient, jwtAuthorization } = require('bima-shark-sdk')

const client = new MailingClient('https://mailing-development.bundesimmo.de', {
  getAuthToken: () => {
    const accessId = 'mailingservice'
    const secretKey = 'ZT...=='

    return jwtAuthorization({ accessId, secretKey })
  }
})

Testing

This SDK uses jest as test framework. Server responses are mocked with nock.

npm ci
npm test
