api.route.patch()

Register a handler for HTTP PATCH requests to the route.

import { api } from '@nitric/sdk';
const PARAM_ID = 'customerId';
const customerRoute = api('public').route(`/customers/:${PARAM_ID}`);
customerRoute.patch((ctx) => {
// construct response for the PATCH: /customers/:customerId request...
const responseBody = {};
ctx.res.json(responseBody);
});

Parameters


match required string

The path matcher to use for the route. Matchers accept path parameters in the form of a colon prefixed string. The string provided will be used as that path parameter's name when calling middleware and handlers. See create a route with path params


...middleware required HttpMiddleware

One or more middleware functions to use as the handler for HTTP requests. Handlers can be sync or async.


Examples

Register a handler for PATCH requests

import { api } from '@nitric/sdk';
const PARAM_ID = 'customerId';
const customerRoute = api('public').route(`/customers/:${PARAM_ID}`);
customerRoute.patch((ctx) => {
const id = ctx.req.params[PARAM_ID];
// handle the PATCH request...
const responseBody = {};
ctx.res.json(responseBody);
});

Chain functions as a single method handler

When multiple functions are provided they will be called as a chain. If one succeeds, it will move on to the next. This allows middleware to be composed into more complex handlers.

import { api } from '@nitric/sdk';
import { validate } from '../middleware';
const PARAM_ID = 'customerId';
const patchCustomer = (ctx) => {
const id = ctx.req.params[PARAM_ID];
// handle the PATCH request...
const responseBody = {};
ctx.res.json(responseBody);
};
const customerRoute = api('public').route(`/customers/:${PARAM_ID}`);
customerRoute.patch(validate, patchCustomer);

Access the request body

The PATCH request body is accessible from the ctx.req object.

import { api } from '@nitric/sdk';
const PARAM_ID = 'customerId';
const customerRoute = api('public').route(`/customers/:${PARAM_ID}`);
customerRoute.patch((ctx) => {
const customerData = ctx.req.data;
// parse, validate and store the request payload...
});
