Client Builder

Client builder is a tool for node that makes it easy to make clients for HTTP APIs.

Quick Setup

import {API, Endpoint} from 'client-builder'

const api = new API({
  base: 'https://api.github.com',
  qsParams: ['access-token'],
  params: {
    'access-token': 'my-access-token',
  },
  responseTransform: (httpResponse) => JSON.parse(httpResponse.body),
})

const editComment = new Endpoint(api, '/repos/:owner/:repo/issues/:number/comments', {
  method: 'GET',
  params: {
    owner: 'tal',
  }
})

const response = endpoint.performAction({
  repo: 'client-builder',
  number: '123',
})

response.then((json) => {
  console.log('first comment', json[0])
})

This is a basic way to setup your endpoints. For any method but GET all parameters other than those specified in qsParams are encoded and placed in the body of the request.

Advanced

The options passed into both Endpoint and API are merged before the rquest is made.

Both classes constructors take the options:

{
  params: {},  // string:string object
  headers: {}, // string:string object
  responseTransform: function() {}, // helper method to transform the response
  qsParams: [], // [string]
}

Params merging

For example:

const api = new API({
  base: 'https://test.com',
  qsParams: ['access-token'],
  params: {
    'access-token': 'my-access-token',
    path_param: 'path',
    to_override: 'top',
  },
  headers: {
    'User-Agent': 'client builder',
  },
})

const editComment = new Endpoint(api, '/endpoint/:path_param', {
  method: 'PATCH',
  params: {
    owner: 'tal',
  },
  headers: {
    'Accept': 'application/json+fmt',
  },
})

const response = endpoint.performAction({
  comment: 'This is a comment',
  to_override: 'overridden',
})

Will yield the following request:

HOST: https://test.com
PATH: /endpoint/path?access-token=my-access-token
HEADERS: User-Agent=client builder;Accept=application/json+fmt;
BODY:
{
  "comment": "This is a comment",
  "owner": "tal",
  "to_override": "overridden"
}
