JSON middleware

The jsonmw() middleware allows you to automatically parse and stringify javascript data when sending or receiving data.

Usage

import metro from '@muze-nl/metro'

const client = metro.client().with( metro.mw.jsonmw({
	space: "\t"
}) )

Then to send and receive data:

let response = await client.post(url, {
	some: 'data'
})
let result
if (response.ok) {
	result = response.data.something
}

The jsonmw middelware will automatically add the Accept: application/json header to your requests.

If the HTTP request supports a body, as in POST, PUT, PATCH and QUERY, it will also add the Content-Type: application/json header. Any data send as the body of the request, will be turned into json.

The body of the response is automatically parsed as json, and made available as response.data.

Configuration Options

The JSON middleware allows you to set the options to use when parsing or stringifying JSON:

reviver: A function to use when parsing JSON, just like JSON.parse
replaced: A function to use when stringifying JSON, just like JSON.stringify
space: The indentation to use when stringifying JSON, just like JSON.stringify
