This parser accepts only UTF-8 encoding of the body and supports automatic inflation of gzip and deflate encodings. A new body object containing the parsed data is populated on the request object after the middleware (i.e. req.body). This object will contain key-value pairs, where the value can be a string or array (when extended is false), or any type (when extended is true). https://github.com/expressjs/body-parser#bodyparserurlencodedoptions 02:37 - Mounting the Strategy - passport.authenticate() This function returns a middleware which runs the strategies. If one of the strategies succeeds, this will set req.user. If you pass no options or callback, and all strategies fail, this will write a 401 to the response. https://github.com/jwalton/passport-api-docs#passportauthenticatestrategyname-options-callback 05:12 - Where the User's Details can be found 05:36 - Correction/Tweak for MongoDB Database Connection 06:35 - Testing the Login 07:18 - Rendering Page with User Details - response.render() Renders a view and sends the rendered HTML string to the client. https://expressjs.com/en/api.html#res.render 08:20 - What Happens When Authentication Fails 09:00 - How This Works 10:10 - Challenge Solution
