Express-respond-simple NPM

express-respond-simple

Simple helpers which create an express middleware, which responds 200 OK, or any other valid code. Optional response body as a string or object can be supplied.

Install

npm install --save express-respond-simple

Use

import express from 'express';
import respond from 'express-respond-simple';
import {respond200, respond402} from 'express-respond-simple';

const app = express();

// status code by number:
app.get('/health', respond200({status: 'good'}));
app.get('/empty', respond200()); // Will actually respond '204 No Content' instead of '200 OK' if no body is given
app.get('/empty-force-200', respond200('', true)); // Will respond '200 OK' with an empty body
app.get('/paywall', respond402('Please add credits to your account and try again.'));

// equivalently, by name:
app.get('/health', respond.ok({status: 'good'}));
app.get('/empty', respond.ok()); // Will actually respond '204 No Content' instead of '200 OK' if no body is given
app.get('/empty-force-200', respond.ok('', true)); // Will respond '200 OK' with an empty body
app.get('/paywall', respond.paymentRequired('Please add credits to your account and try again.'));


app.listen(process.env.PORT || 3000);
