Summary

rauricoste-request is a fluent api to send HTTP request using Promise as its core data object.

It is written using nodejs libraries. Then, it should be compiled with a tool like browserify

API

A HTTP call consists on some modifiers calls followed by a callers call. It will always return a Promise. If the HTTP code is >= 400, the promise response will contain an error with details.

Exemple :

new Request()
        .json()
        .withHeader("Authorization", "Bearer 12345")
        .withQueryParams({
            start_time: "2017-01-01",
            end_time: "2017-12-31"
        })
        .get("https://api.domain.com").then(response => {
            // extract the response body and status code
            const { body, statusCode } = response;
            // parse the body as a json object
            const json = JSON.parse(body);
        }).catch(err => {
            // extract the response and request
            const { request, res } = err;
            // extract the response status code and the response body
            const { statusCode, body } = res;
        })

callers

• get(url) : launch the request with the method GET on the url url

• post(url, body) : launch the request with the method POST on the url url with the body body.

body can be a string or an object (cf withBody method)

• call(url) : launch the request with the current method provided by withMethod on the url url.

Default method is GET

modifiers

• withBody(string or object) : add a body to the request. If the body is an object, it will convert it the same way it does for query parameters. If calling a POST, you shoud pass an object. If calling a JSON API, you should convert the object to JSON using JSON.stringify(object)

Exemple : withBody({start: 2017, end: 2018}) will convert to start=2017&end=2018.

• withQueryParams(string or object) : adds query parameters on the url called. If this method is called several times, only last call is effective.

Exemple : withQueryParams({start: "a", end: "z"}) : will add start=a&end=z

• withHeaders(object) adds a list of headers

Exemple : withHeaders({Authorization: "Bearer 12345"}) : adds the header Authorization: Bearer 12345

• withHeader(key, value) adds a header

Exemple : withHeaders("Authorization", "Bearer 12345") : adds the header Authorization: Bearer 12345

• withMethod(value) : will change the HTTP method. Methods can be GET, PUT, POST, DELETE, .... Defaults : GET

• withUrl(url) : will change the base URL called. This method will not modify query parameters

• withCredentials(boolean) : if set to true, credentials will be sent. It can be usefull when using CORS

content-types

• talkType(type) : is a shortcut for .withHeaders({"Content-Type": type, "Accept": type})

• json() : is a shortcut for .talkType("application/json")

• xml() : is a shortcut for .talkType("application/xml")
