FetchJSONify.js

NPM version Build status

Fetch JSONify is a mixin for the Fetch API for browsers and Node.js that stringifies JSON and sets the Content-Type header if not given. It's functional and immutable, in that it doesn't modify any properties given to it.

Installing

npm install fetch-jsonify

FetchJSONify.js follows semantic versioning, so feel free to depend on its major version with something like >= 1.0.0 < 2 (a.k.a ^1.0.0).

Using

Wrap the native fetch function with the one from FetchJSONify.js:

var fetchWithJsonify = require("fetch-jsonify")(fetch)

Then pass any value or object you'd like stringified under the json property:

fetch("/models", {method: "POST", json: {name: "John"}})

That property will be stringified with JSON.stringify and passed on to the original fetch function under the body property. The Content-Type header will be set to application/json if it's not set.

Content-Type

To set a custom Content-Type header, just pass it as you normally would:

fetch("/models", {
  method: "POST",
  headers: {"Content-Type": "application/vnd.model+json"},
  json: {name: "John"}
})

Browser

Browsers have the Fetch API available at window.fetch:

var fetch = require("fetch-jsonify")(window.fetch)
fetch("/models", {method: "POST", json: {name: "John"}})

Node.js

Node.js doesn't have a built-in implementation of the Fetch API, but you can use any library with a compatible interface, such as node-fetch:

var fetch = require("fetch-jsonify")(require("node-fetch"))
fetch("/models", {method: "POST", json: {name: "John"}})
