api-core

Base API definitions for the Availity REST API.

AvApi

AvApi is a class that wraps a provided http service with helper functions.

Features

• Automatic polling of restful endpoints with timeouts
• Simple URI builder for API resources
• Life-cycle hooks into HTTP calls for GET, PUT, POST, and DELETE

Usage

import AvApi from '@availity/api-core';

new AvApi(http, promise, options);

Options

http

Either Angular's $http service or Axios (or compatible lib).

promise

Either Angular $q or equivalent Promise object.

config

Either Angular $http or axios config object

Config

config.api

Default true. When true, the url is built out by joining path, version, and name or just url if no name is defined. The id is also added when appropriate. When api is false, all calls just use url. URL pattern: path/version/name

config.url

This is used for requests when config.api is false or name is undefined;

config.path

Used for url building when config.api is true. URL pattern path/version/name

config.version

Default v1. Used for url building when config.api is true. URL pattern path/version/name

config.name

The name of the resource. Used for url building when api is true. (path/version/name)

config.cacheBust

Disable caching for every request by adding a cacheBust parameter to the call.

Accepts a boolean, function, or some value:

• If true, a timestamp is generated and used
• If a function, it is called and return value is used
• If a value is passed then the cache bust param is set to this value.

config.pageBust

Bust the browser cache on page load, and keep its value for lifecycle of the page. Same behavior as cacheBust except if true, a value is only generated once and re-used. A hard refresh of page resets the pageBust value. To manually set the pageBust value call without changing the config, use setPageBust(value) which will set the it to value or if undefined generate a timestamp.

config.sessionBust

Default true. Attempts to read a value in local storage that is generated at login. This forces the browser to bust the cache when a new session has started. If the local storage value is not found, uses the pageBust value.

config.polling

Default true. If true and rest services return 202 statuc code, AvApi will attempt to poll on predefined internvals until the retries are exhausted or the api returns non 202 response.

config.pollingIntervals

An array of intervals (ms) to wait before making another request. Default is 1, 2, 5, then 10 seconds. After all the intervals have been used, AvApi will stop attempting requests and return the last response.

config.getHeader

Used for polling, if the http service used has special logic to get a header value, then define this function to handle that logic. If defined, it is called with (response, headerKey). If not defined, attempts to get key from response.headers[key].

Methods

Each method can use an after function, (ex. afterGet with get). These are available to modify the response before it is resolved. Each method that has data available has a before function in order to modify data before the call is made.

All methods accept a config object, which is merged into the resources config for that call only.

create or post

Makes HTTP POST request.

create(data, config);
// or 
post(data, config);

postGet

Makes HTTP POST using X-HTTP-Method-Override = 'GET'. There server must support override methods for the request to succeed.

postGet(data, config);

get

Retrieves an entity by ID. Makes HTTP GET call with /id in url.

get(id, config);

query

The query function is designed to fetch collections and search the API. Makes HTTP GET request with query params.

query(config);

update or put

Update an entity with a PUT call. When an id is passed in, /id is added to the url.

update(id, data, config);
// or wihthout id
update(data, config);
// or
put(id, data, config);
// or or without it
put(data, config);

remove or delete

Remove an entity with a DELETE call. When an id is passed in, /id is added to the url. If the first parameter is a string or number, it is treated as an ID, otherwise data.

remove(id, config);
// or without id
remove(data, config);
// or
delete(data, config);
// or without id
delete(config);

AvMicroservice

AvMicroservice extends AvApi and thus can call the same methods. It has slightly different config options used for some child apis.
