TSLint marks body-parser as deprecated

Question

I have the Typescript code below:

import * as express from 'express'; import * as bodyParser from 'body-parser';  ... const app: express.Application = express();  app.use(bodyParser.json());  

In VSCode the bodyParser on the last line is marked with yellow squiggles saying that body-parser is deprecated.

In the .d.ts file I see the following:

/** @deprecated */ declare function bodyParser(     options?: bodyParser.OptionsJson & bodyParser.OptionsText & bodyParser.OptionsUrlencoded, ): NextHandleFunction;  declare namespace bodyParser { ...     function json(options?: OptionsJson): NextHandleFunction; 

Why is the linter complaining about the body-parser function while I do not use it as a function in my code? Am I missing something in a tsconfig.json file to prevent this? Compiling doesn't seem to be a problem.

Answer 1

BodyParse is built into Express js

So now you don't have to install body-parser, do this instead.

app.use(express.json()); 

Answer 2

Do not use body-parser anymore

Since Express 4.16+ the body parsing functionality has become builtin with express

So, you can simply do

app.use(express.urlencoded({extended: true})); app.use(express.json()) // To parse the incoming requests with JSON payloads 

using express directly, without having to install body-parser.

uninstall body-parser using npm uninstall body-parser

Then you can access the POST data, using req.body

app.post("/yourpath", (req, res)=>{      var postData = req.body;      //Or if body comes as string,      var postData = JSON.parse(req.body); });
