Headers Factory
Opinionated headers factory for easy use with fetch and other AJAX things too I guess.
99% of the time I'm hitting a JSON API in CORS mode, getting or posting some data, and maybe sending up a JWT token.
So I've designed this module to make that use case super easy.
Install
# with npm
npm install --save headersfactory
# with yarn
yarn add headersfactory
Use
headersFactory(jwtToken)(method, data)
// with es6
import headersFactory from 'headersfactory';
// with CommonJS
const headersFactory = require('headersfactory');
// Example get with no JWT token
const githubUrl = 'https://api.github.com/users/tylerbuchea/repos?sort=updated';
const githubHeaders = headersFactory()('get');
fetch(url, githubHeaders)
.then(response => response.json())
.then(console.log)
.then(console.error);
// Example post and get with JWT token
const madeupUrl = 'https://api.example.com/users';
const jwtToken = 'IMAJWTTOKEN'; // no need add "Bearer " it is added automatically
// No we can use headers() to generate new headers with the JWT token automatically connected
const headers = headersFactory(jwtToken);
const headersPost = headers('post', { age: 27 }); // JSON is automatically strinigified and attached to the body of the request
fetch(madeupUrl, headersPost)
.then(response => response.json())
.then(console.log)
.then(console.error);
// We can use headers() again and the JWT is still automatically attached even though we're performing a different call
const headersGet = headers('get');
fetch(madeupUrl, headersGet)
.then(response => response.json())
.then(console.log)
.then(console.error);
The actual code
This whole module is super tiny feel free to just copy paste it into your own file locally and modify as opposed to npm install
-ing it.
'use strict';
function headersFactory(jwtToken) {
return function headers(method, data, headers) {
var header = {
mode: 'cors',
method: method,
headers: {
Accept: 'application/json',
'Content-Type': 'application/json',
},
};
if (jwtToken) header.headers.Authorization = 'Bearer ' + jwtToken;
if (data) header.body = JSON.stringify(data);
return header;
};
}
module.exports = headersFactory;
