fetchex is a simple wrapper over the fetch api and is isomorphic, i.e, can be used in the browser as well as in the node environment.

• Has easy reponse wrapper for json, texts and formData
• Supports GET, POST, PUT, PATCH, DELETE requests
• Also has a vanilla fetch method which does the same as the raw fetch API

For GET request type which does not have any request body:

fetchex.get(url, accept, contentType, init)

For other request types which may have a request body:

fetchex.get(url, body, accept, contentType, init)

Default value for accept and contentType is json.

GET something:

fetchex.get('/something.json').then(success).catch(failure);

GET something with headers

fetchex.get('/something,json', 'json', 'json', {
  headers: {
    'Accept': 'application/json',
    'X-Request-With': 'fetch'
  }
});

POST/PATCH some JSON data:

fetchex.post('/something.json', JSON.stringify({ user: {name: 'Simon' }));

Or PATCH/POST regular form data:

fetchex.patch('/something.json', 'user[name]=Simon', 'json', 'form');

POST/PATCH some other body type:

Sending base64 string and expecting a plain text in response

fetchex.post('/something.json', btoa('hello'), 'text', 'application/base64');

POST/PATCH buffers:

const arrayBuffer = new ArrayBuffer(128);
const view   = new Int32Array(buffer);

for (let i = 0; i < view.length; i++)
  view[i] = Math.pow(i, 2);

fetchex.patch('/something.json', buffer, 'json', 'application/octet-stream');
