Welcome, aspiring developers! Today, we’re diving into the spectacular world of building a fundamental app using Node, Express, and TypeScript. This blog post will guide you on how to shift your app to serverless functions with seamless integration to Azure, using a hero and villain theme throughout. Let’s soar into the details!
Why Choose a Serverless Architecture?
Creating APIs is fun and flexible with Node and Express, but maintaining a server can feel like a relentless chore. Server upkeep often comes with hosting costs and scalability issues. Transitioning to a serverless setup alleviates these burdens, thereby:
- Reducing costs significantly.
- Simplifying server maintenance.
- Allowing effortless scaling.
- Minimizing the middleware surface area required.
Although it may not be a perfect solution for everyone, if these factors resonate with you, serverless might just be your superhero!
Prerequisites
Before you unleash your coding powers, ensure you have the following:
- Access to a database. You can start with the free Azure Free Trial or Azure Cosmos DB.
- Create a Cosmos DB database.
- Within it, set up two containers: heroes and villains, each with a partition key named id.
- Duplicate the env.example file and rename it to .env. Fill in the required variables with your database info.
Getting Started
Now that you’re set up, let’s get into action!
- Clone this repository:
- Navigate into your project folder:
- Install necessary npm packages:
- Build the Node Express and Angular code:
- Run the application:
git clone https://github.com/johnpapa/heroes-angular-serverless.git heroes
cd heroes
npm install
npm run node-ng:build
npm run node:start
Debugging Node, Express, and Angular
If things go south, fear not! There’s a straight path to debugging:
- Modify proxy.conf.json and set the port to 7070.
- Open the VS Code Command Palette (F11) and type View: Show Debug, then hit ENTER.
- Select Debug Express and Angular, followed by pressing F5.
- Launch the browser and go to http://localhost:7070.
- Set breakpoints as required.
Troubleshooting Tips
If you encounter any bumps on your heroic journey:
- Double-check your database connection information in both the .env and functionslocal.settings.json files.
- Ensure all necessary npm packages are correctly installed.
- Restart your application after making any configuration changes.
