Deprecated usage of bodyParser() and npm Invalid warning

[stevenay]

In Exercise 2 - Book Library application, the usage of bodyParser() constructor in server.js has been deprecated as of 2014-06-19.

app.use(bodyParser()); // deprecated

Instead of this line, it needs to be used as the following code:

app.use(bodyParser.urlencoded({
  extended: true
}));

app.use(bodyParser.json());

In addition, when installing the npm packages, body-parser dependency is listed as "~1.9.1" in the package.json file. It will cause the npm ERR! invalid: [email protected] warning when you listed your installed npm packages by the command of npm list.

(Personally, I solved this warning by npm update command.)

So instead of "~1.9.1", it should be listed as "~1.13.3" (as the time of this issue writing, the latest body-parser is "1.13.3").

Thanks.
