The package @ts-stack/body-parser is a fork of body-parser - the native ExpressJS package. It is written in TypeScript in ESM format, without support for older versions of Node.js < v20.6.0. To install it, run the following command:
npm install @ts-stack/body-parser This package parses the body of an HTTP request that has the following types: JSON, Raw, Text, URL-encoded. You can use it as follows:
import http from 'http'; import { getJsonParser } from '@ts-stack/body-parser'; const jsonParser = getJsonParser({ limit: '1kb' }); http.createServer(async function (req, res) { try { const body = await jsonParser(req, req.headers); res.statusCode = 200; res.setHeader('Content-Type', 'text/plain') res.write('you posted:\n'); res.end(JSON.stringify(body)); } catch (err: any) { // handling an error } }); Alternatively, you can use the BodyParserGroup helper. It is designed for cases when you do not know which parser is needed for a specific route. When creating an instance of the BodyParserGroup class, you can pass options for the corresponding parsers, after which you can use the parse method as follows:
import { BodyParserGroup } from '@ts-stack/body-parser'; const bodyParserGroup = new BodyParserGroup({ jsonOptions: config.jsonOptions, textOptions: config.textOptions, urlencodedOptions: config.urlencodedOptions, rawOptions: config.rawOptions, }); const body = await bodyParserGroup.parse(req, req.headers, {});
