Fredux API utils

Description

This library provides a set of functions which build http requests. This library relies on the standard fetch api, and should be polyfilled in older browsers.

Installing fredux-api-utils

npm install --save fredux-api-utils

Usage

To send some URL params:

import { get } from "fredux-api-utils";

get("/users", { params: { key1: "value1", key2: ["value2", "value3"] } })
  .then(response => console.log(response))
  .catch(error => console.log(error));

To send an object as the JSON body:

import { post } from "fredux-api-utils";

post("/users", { body: {name: "Peter"} })
  .then(response => console.log(response))
  .catch(error => console.log(error));

To send form data as the body:

import { post } from "fredux-api-utils";

post("/users", { formData: { key1: "value1", key2: ["value2", "value3"] } })
  .then(response => console.log(response))
  .catch(error => console.log(error));

To send form data as FormData object:

import { post } from "fredux-api-utils";

const formData = new FormData();
formData.append("name", "My Name");
formData.append("file", new Blob(["Some notes..."], { type: "text/plain" }));

// If there's not a Content-Type header, will use multipart/form-data
post("/users", { formData })
  .then(response => console.log(response))
  .catch(error => console.log(error));

To add some headers:

import { post } from "fredux-api-utils";

post("/users", { headers: { "my-custom-header": "custom" } })
  .then(response => console.log(response))
  .catch(error => console.log(error));

NOTE: when passing a body option, Content-Type: application/json will always be set unless you explicitely pass a Content-Type. The same goes with formData and Content-Type: x-www-form-urlencoded unless you pass a FormData object. In this case, Content-Type: multipart/form-data will be set automatically as default (you can override it anyway).

To set several other options just pass them:

import { get } from "fredux-api-utils";

get("/users", { timeout: 2000, mode: "no-cors" })
  .then(response => console.log(response))
  .catch(error => console.log(error));

Available API methods

• get(endpoint, options)
• post(endpoint, options)
• put(endpoint, options)
• patch(endpoint, options)
• del(endpoint, options)

Where endpoint is a string with the resource you wish to fetch and options is an object containing custom settings you want to apply to the request. The possible options are:

• body: any JSON body.
• formData: any data to be passed as a x-www-form-urlencoded object or a FormData instance.
• params: an object containing query params.
• headers: any headers you want to add to your request.
• timeout: any timeout in milliseconds. The default is 0.
• credentials: sets the policy for sending cookies. One of omit, same-origin, or include. Using same-origin as default.
• mode: the mode you want to use for the request, e.g., cors, no-cors, same-origin, or navigate. Defaults to cors.
• redirect: the redirect mode to use, e.g. follow, error, or manual. Defaults to follow.
• referrer: the referrer of the request, Defaults to client.
• cache: cache mode for the request, e.g. default, no-store, reload, no-cache, force-cache,only-if-cached. Defaults to default.

This options, for the most part adhere to the fetch Request API.
