Where can i deploy a node js API with a Mysql database? what are some simple good options?

brew install and brew update hang with error: 'refs/remotes/origin/master': unknown revision or path not in the working tree.

Nest.png
Nowadays we use JavaScript not only for front-end applications but also for server-side applications with the help of node.js. There are lots of popular frameworks out there for node.js. Express is the most popular framework so far. but there are other frameworks like Meteor, Koa, Sails, Hapi, Loopback, etc. Nest.js is also a server-side node.js framework built by Kamil Mysliwiec and the community, In the past 2 years nest.js become the fastest-growing node.js technology, and currently, it has 35.9K GitHub stars.

As I mentioned before Node.js (for the server-side) has plenty of great libraries, But none of them solves the main problem of architecture. Nest provides an out-of-the-box application architecture that allows developers and teams to create highly testable, scalable, loosely coupled, and easily maintainable applications. The architecture is heavily inspired by Angular.

What so special about this framework?

Nest JS is an open-source framework for building efficient, scalable Node.js server-side applications.

Built-in typescript support. (yet still enables developers to code in pure JavaScript).

Combines elements of Object-Oriented Programming, Functional Programming, and Reactive Programming.

Nest.js provides a similar kind of architecture to other server-side applications like .NET Core, Java Spring Boot, etc.

Under the hood, Nest makes use of robust HTTP Server frameworks like Express (the default) and optionally can be configured to use Fastify as well.

Let’s create a “Hello World” app with Nest JS.

First of all you need to install Node.js. Click here to download Node.js for your operating system.

Then You need Nest-CLI. This helps you to initialize and develop your applications. Open the command line and execute this command.

npm install -g @nestjs/cli Now you can generate a new project using this command. Replace “my-nest-project” with your project name. nest new my-nest-project Go to the project directory and execute the below command to start the application. npm run start:dev

That's it, Now In your browser, open http://localhost:3000 to see a new application running. The app will automatically recompile and reload when you change any of the source files.

You can easily learn lots of things by referring to Nest JS documentation. The Nest JS documentation is well-maintained and contains a lot of information with real examples. https://docs.nestjs.com/

Happy Coding 🙂

I need my website refresh to top but have failed finding a solution for it. Can anyone who knows about this please post a solution for this?

ERROR 1524 (HY000): Plugin 'mysql_native_(Password)' is not loaded

I wasn't prompted to set a root password during the installation and so whenever I tried to use mysql via the mysql -u root -p command. I got this error => Access denied for user 'root'@'localhost'.

So I searched stack overflow and found an answer that involved setting the authentication plugin to mysql_native_password. the query looked something like this...

UPDATE user SET plugin="mysql_native_password";
However, for some reason I typed the command manually instead of copying it and I seem to have written mysql-native-password instead of mysql_native_password (stupid me!!!)

now I tried to access the mysql shell in various ways but I always get the following error!

ERROR 1524 (HY000): Plugin 'mysql-native-password' is not loaded

Tried with safe mode : sudo mysqld_safe --skip-grant-tables &
also happens to be the same problem ,
