In this section you will create three simple Node.js apps. One of them will just connect to the database, the second will perform basic Insert, Update, Delete, and Select, and the third one will make use of Sequelize, one of the most popular Node.js Object-relational mappers, to execute the same operations.
- Jun 26, 2017 node server.js // Example app listening on port 3000! Now open your browser and visit: localhost:3000 and you should see Hello World! You’ve just created a server with Node.js and Express! Setting up the index view. Instead of responding with text when someone visits our root route, we’d like to respond with an HTML file.
- Packaging Your App into a File. Apart from shipping your app by copying all of its source files, you can also package your app into an asar archive to avoid exposing your app's source code to users. To use an asar archive to replace the app folder, you need to rename the archive to app.asar, and put it under Electron's resources directory like below, and Electron will then try to read the.
- 3 Make your Node.js app up to 100x faster In this section you will create three simple Node.js apps. One of them will just connect to the database, the second will perform basic Insert, Update, Delete, and Select, and the third one will make use of Sequelize, one of the most popular Node.js Object-relational mappers, to execute the same operations.
- I am learning node.js and I am trying to run the app.js file using the command node app.js but the bash returns nothing (no errors either). Here are the steps I followed: $ brew install node $ sudo npm install -g express $ sudo npm install -g express-generator. After i get into a new folder I created I run $ express testsite -hogan -c less.
Step 2.1 Create a Node.js app that connects to SQL Server and executes queries
Create a new project directory and initialize Node dependencies.
Create a database that will be used for the rest of this tutorial by connecting to SQL Server using sqlcmd and executing the following statement.
Node.js® is a JavaScript runtime built on Chrome's V8 JavaScript engine.
Now you will create a simple Node.js app that connects to SQL Server.
Using your favorite editor, create a file named connect.js in the SqlServerSample folder. Copy and paste the below contents into the file.
Run the application.
Using your favorite text editor, create a file called CreateTestData.sql in the SqlServerSample folder. Copy and paste the following the T-SQL code inside it. This will create a schema, table, and insert a few rows.
Connect to the database using sqlcmd and run the SQL script to create the schema, table, and insert some rows.
Using your favorite text editor, create a new file called crud.js in the SqlServerSample folder. Copy and paste the following code inside it. This will insert, update, delete, and read a few rows.

Run the crud.js app to see the results
Step 2.2 Create a Node.js app that connects to SQL Server using the popular Sequelize ORM
Create the app directory and initialize Node dependencies.
- Open your favourite text editor and create the file orm.js in the directory SqlServerSequelizeSample.
- Paste the contents below into orm.js
- Update the variable for password to use your own password specified in the first module.
- Save and close orm.js
Run the orm.js app
