Wraps your micro service function to catch errors and display them as JSON.

npm install micro-json-error --save

const { createError } = require('micro');
const jsonError = require('micro-json-error');

module.exports = jsonError(async function (req, res) {
  throw createError(400, 'Invalid data');
});

jsonError(fn, { httpStatusCode = null, onError = null });

• httpStatusCode - Overrides the statusCode from the error for the http response status code. Useful if you always want to return a 200, and show the original statusCode in the JSON body.
• onError - Callback function that will be passed the error. Useful for logging.
