with native http module

const { createServer } = require('http');

const jbody = require('@ukab/jbody');

// // with config
// const jsonParser = jbody({
//   exclude: ['/contact'] // optional
//   excludeRegex: [new RegExp('/users/.*')] // optional
//   sizeLimitInBytes: 1024 // optional
// });

// without config

const jsonParser = jbody();

createServer(async (req, res) => {
  const url = new URL(req.url);

  const ctx = { req, res, url: url.pathname };

  await jsonParser(ctx);

  res.end(JSON.stringify({
    data: ctx.body,
  }));

}).listen(3000);

with koa

app.use(async (ctx, next) => {
   await jsonParser(ctx);
   await next();
});

with express

app.use((req, res, next) => {
  const ctx = { req, res, url: req.url };

   jsonParser(ctx)
    .then(() => {
      next();
    }).catch(next);
});
