for internal use only - Just draft idea to easily fetch API in our apps
fetchjson
Fetch wrapper to easily request an API, simply create a native fetch initialized with :
- header
Content-Type=application/json
- default hostname & authorization credentials params
- optional method prefix
Install
yarn add @jellyfish-commuting/fetchjson
or
npm install @jellyfish-commuting/fetchjson
Usage
import fetchjson from '@jellyfish-commuting/fetchjson';
// Init params
const init = {
hostname: 'https://fake-api.io',
authorization: 'Bearer API_KEY',
};
// Fetch (https://fake-api.io/v1/users?limit=10)
fetchjson('v1/users', { limit: 10 }, init)
.then(payload => console.log(payload));
// Create
const data = { firstname: 'John', lastname: 'Doe' };
fetchjson('POST v1/users', data, init)
.then(({ id )} => console.log(`User #${id} created successfully !`));
// Update
data.firstname = 'Johnna';
fetchjson('PUT v1/users/1', data, init)
.then(() => console.log('User updated successfully !'));
// Delete
fetchjson('DELETE v1/users/1', null, init)
.then(() => console.log('User deleted successfully !'));
// Retrieve http response
// payload has a not enumerable prop "_response"
fetchjson('v1/users', null, init)
.then(payload => {
const header = payload._response.headers.get('x-powered-by');
console.log(`Powered by ${header || 'Unknow'}`),
});
Params
fetchjson(url, data, init);

};
// Endpoint will be prepend with hostname
fetchjson('POST v1/users', { firstname: 'John' }, init);
// Authorization will be ignored
// -> hostname is different than init.hostname
fetchjson('https://vendor-api.io/v1/my-account', init);
