Express.js & Node.js Course for Beginners - Full Tutorial

[@TheSparkart]

I'm surprised this video doesn't have more views.... It's probably the most detailed and concise tutorial I've found on node and express. Great explanations, other tutorials I've seen are just do this do that... no explanation involved.

[@starmachines]

Bahadir, this tutorial is exceptional. In particular, your explanations are very thorough and easily understood. Thanks for doing this.

[@kevingagnon1234]

Excellent video. I spent my entire Saturday and only got through 2/3rds of the video. I'm a newbie to Node.js and Express and was looking for a good framework to use for the #AVRSpy project I'm working on. Although I've opted for SQLite without Sequelizer for my project, I've been able to parallel your app with the smaller db. I truly appreciated the MVC approach you took with a basic Express generator app. Taking Sequelizer out of the picture has left me unsure how to utilize the "models" feature if I'm going to use SQLite though. Right now, I'm doing all of the work from the Controllers js files. Thanks again for a great video: I only had to hit pause and say 'WHAT DID HE JUST DO?' about 234 times.

@Buzz_Team - at 21:25 , when I edit the Package.JSON to change the scripts start line to include nodemon, I keep getting error "$NODE_ENV was unexpected at this time." when I do 'npm start' command. I have everything like the tutorial but it is not working. Can you help pls ?

You can generate the migration and model from the command line if you installed sequelize-cli: Example: `sequelize model:generate --name Leads --attributes email:string` **Note:** Sequelize automatically generates the id, updatedAt and createdAt fields.

[@KhwiloWatai012]

Helpful command. I think there is no use of writing all the code if there is a command to generate the same.

[@skyezone9307]

Thanks! This helps with less head scratch to think where did the migration come from.

39:46 --> When I run the "sequelize db:migrate" command I get an error which states: "Cannot read property 'toString' of undefined". Any idea how can I resolve this issue?

[@diegoloiola7663]

Check if you correctly typed the types in the migrations folder and in the models folder in Users.js. There is a small difference, one uses DataTypes.STRING (the type in uppercase) and the other uses Sequelize.STRING I've already come across this error because one of them was with the lowercase letter

[@Habitatu]

Thank you Bahadir. This was an amazing tutorial and i learned so much. If you work through it slowly, fixing errors as you go, and referring to the github code, it will work at the end. There are some things which are shown in the video which are different in the github code and that's why its necessary to cross reference. Question: now that we have set up access flags and sessions, how do we implement it so that each user has access to his own list of leads, rather than a common pool of leads? I can think of two solutions: 1. Collect all leads in one table with an owner flag for each, and sort the returned leads by owner 2. Create a separate table for each user, and list all the leads from their table Which is preferred and why?

Terminal on a mac is equivalent to something called bash. CMD is Windows specific. You will need to probably install Git (which will install a bash terminal) or just a bash terminal by itself to run some of these commands. Bash is native to linux based OS'
