fetch-reply-with

Simplifies unit tests by intercepting fetch requests and returning mocked responses.

Install

npm install --save-dev fetch-reply-with

Usage

require('fetch-reply-with'); // <- `fetch` is now globally available

// intercept GET http://orcascan.com and reply with...
fetch('http://orcascan.com', {

    // regular fetch option
    method: 'GET',

    // add reply for this fetch
    replyWith: {
        status: 200,
        body: 'Barcode Scanner app',
        headers: {
            'Content-Type': 'text/html'
        },
        delay: 500 // miliseconds to wait before responding (default = 0)
    }
});

// execute fetch request
fetch('http://orcascan.com').then(function(res){
    return res.text();
})
.then(function(text){
    // text === `Barcode Scanner app`
});

Couple of things to note:

• Requests not setup with replyWith are executed as normal
• A replyWith can be modified by redefining the replyWith
