00:00 - Introduction 00:16 - Registration Form 01:08 - POST Route 01:25 - 3 Steps to Registering a User 01:44 - Getting Form Data - bodyParser.urlEncoded() Returns middleware that only parses urlencoded bodies and only looks at requests where the Content-Type header matches the type option. A new body object containing the parsed data is populated on the request object after the middleware (i.e. req.body). https://github.com/expressjs/body-parser#bodyparserurlencodedoptions 02:18 - Middleware for Database Work 02:38 - Check if User Already Exists - db.collection.findOne() Returns one document that satisfies the specified query criteria on the collection or view. If multiple documents satisfy the query, this method returns the first document according to the natural order which reflects the order of documents on the disk. https://docs.mongodb.com/manual/reference/method/db.collection.findOne/ 04:34 - Creating a User Document in the Database - db.collection.insertOne() Inserts a single document into MongoDB. If documents passed in do not contain the _id field, one will be added to each of the documents missing it by the driver, mutating the document. http://mongodb.github.io/node-mongodb-native/3.6/api/Collection.html#insertOne 06:40 - Logging in the New User - 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 07:32 - Redirecting the User to their Profile 08:40 - Testing the Registration 10:30 - Challenge Solution 16:06 - Explanation of Solution
