@types/koa-bodyparser

What is @types/koa-bodyparser?

@types/koa-bodyparser provides TypeScript definitions for the koa-bodyparser middleware, which is used to parse the body of HTTP requests in Koa applications.

What are @types/koa-bodyparser's main functionalities?

Basic Usage

This code demonstrates the basic usage of koa-bodyparser. It sets up a Koa application, uses the bodyParser middleware to parse incoming request bodies, and then responds with the parsed body.

const Koa = require('koa');
const bodyParser = require('koa-bodyparser');
const app = new Koa();

app.use(bodyParser());

app.use(async ctx => {
  ctx.body = ctx.request.body;
});

app.listen(3000);

Custom Options

This code demonstrates how to use custom options with koa-bodyparser. It configures the middleware to parse JSON, form, and text bodies with specific size limits.

const Koa = require('koa');
const bodyParser = require('koa-bodyparser');
const app = new Koa();

app.use(bodyParser({
  enableTypes: ['json', 'form', 'text'],
  jsonLimit: '1mb',
  textLimit: '1mb',
  formLimit: '1mb'
}));

app.use(async ctx => {
  ctx.body = ctx.request.body;
});

app.listen(3000);

Error Handling

This code demonstrates how to handle errors in koa-bodyparser. It sets up a custom error handler that throws a 422 error if the body parsing fails.

const Koa = require('koa');
const bodyParser = require('koa-bodyparser');
const app = new Koa();

app.use(bodyParser({
  onerror: (err, ctx) => {
    ctx.throw('body parse error', 422);
  }
}));

app.use(async ctx => {
  ctx.body = ctx.request.body;
});

app.listen(3000);

Other packages similar to @types/koa-bodyparser

koa-body

koa-body is a more comprehensive body parser middleware for Koa that supports multipart, urlencoded, and JSON request bodies. It offers more features compared to koa-bodyparser, such as file uploads and custom handling of multipart requests.

koa-multer

koa-multer is a middleware for handling multipart/form-data, which is primarily used for uploading files. It is based on multer and provides more advanced file handling capabilities compared to koa-bodyparser.

koa-json-body

koa-json-body is a simpler alternative to koa-bodyparser that focuses solely on parsing JSON request bodies. It is lightweight and easy to use but lacks the flexibility of handling other content types.
