Error starting server: body-parser method deprecated

[sbutterfield]

node server.js yields errors:
body-parser deprecated bodyParser: use individual json/urlencoded middlewares server.js:31:9
body-parser deprecated urlencoded: explicitly specify "extended: true" for extended parsing node_modules/body-parser/index.js:74:29

bodyParser constructor should no longer be explicitly called. Update server.js line 31 to:

app.use(bodyParser.json());
