halfpenny // COINS API Javascript client

What is a halfpenny, anyway? Beyond an old-timey coin (AKA a pence), halfpenny is the official javascript API client for the COINS platform.

alpha warning

halfpenny is still in active development! it is not ready for public usage!

TODO:

• support UMD and browser compatibility.
• Auto-generate documentation from API client

peer dependencies

axios

A HTTP request agent is required to retrieve the Client source code and to make requests. Axios was chosen as that client in order to support both server and browser environments.

localstorage

In order to persist data to disk, a localstorage interface is required. In the browser, this means supplying window.localStorage in the browser, and using node-localstorage or dom-storage on the server.

basic configuration:

See examples The above configuration parameters are required. Note that the 'requestFn' must be promisified

How it works:

The source code for the client is auto-generated during the build process of the API itself. The API then bundles and serves the source code from /client/client.js.

This package retrieves the bundled source code and evaluates it. The result is an object with properties corresponding to each method exposed by an API endpoint (e.g. ScansApi.get()).

examples

const agent = require('axios');
const DomStorage = require('dom-storage');
const store = new DomStorage('/path/to/file', {strict: true});
const apiClientOptions = {
    xhrAgent: agent,
    baseUrl: 'http://localhost:8800', // hostname:port of nodeapi service
    store: store
};
const clientReady = require('halfpenny')(apiClientOptions)
    .catch((err) => {
        //whoops
    });

// login
clientReady.then((client) => {
    return client.auth.login('username', 'password');
});

// get scans
clientReady.then((client) => {
    return client.ScansApi.get(null, 'M87100000')
});
