A Wordpress api client

Description

A very simple Javascript client for accessing a Wordpress site's API
Currently only offers access to Posts and Terms following the standard schema
(very unstable)

Documentation

1. Instantiate a WPClient instance passing in your wordpress site's url
2. Call either WPClient::getPosts or WPClient::getTerms passing in a callback and args
3. Receive Result<WPResponse, Err> and check with isOk / isErr or unwrap() to get value

A WPResponse contains meta data about the query as well as the received content

interface WPResponse<T> {
    meta: QueryMeta
    content: T // currently either BasicPost[] or Term[]
}

// not in all queries so possibility to be undefined, will move to Maybe<T> in the future
interface QueryMeta {
  count: number | undefined,
  totalPages: number | undefined
}

-- Notes

• Currently getPosts and getTerms are curried
  • To call them either pass in callback then args like so:

    WPClient::getPosts(callback)(args)

  • Or save to a variable:

    const query = WPClient::getPosts(callback)
    query(args)

• Uses fetch and promises, use polyfills if supporting legacy browsers
• Caches fetch requests in memory during a session

-- Example

import { WPClient, unwrap } from "pp-wapi"

// Instantiate client
const client = new WPClient("www.testwp.com")

// Callback to run on request completion
const callback = result => console.log(unwrap(result))

// Post query args, see below for list of possible values
const args = {
    page: 2,
    categories: [ 1, 4 ]
}
client.getPosts(callback)(args)
