Building a Fastapi Two Html App with Templates

Building a Fastapi Two Html App with Templates is a great way to create dynamic web applications.

Fastapi is a modern, fast (high-performance), web framework for building APIs with Python 3.7+ based on standard Python type hints.

To create a Fastapi Two Html App with Templates, we need to install the required packages, including Fastapi and Jinja2.

Jinja2 is a templating engine that allows us to render dynamic HTML templates.

FastAPI doesn't provide its own HTML rendering templates, so we need to integrate a template engine.

We can use Jinja, which is a popular choice for FastAPI, to render our HTML templates.

To integrate Jinja, it's very straightforward and seamless.

We can use the url_for() function to link to static files, such as CSS stylesheets, in our HTML templates.

For example, we can link to a CSS file at static/styles.css.

FastAPI applications can be run after setting up templates and static files.

To run your FastAPI application, simply visit http://localhost:8000 in your browser. You should see "Hello, World!" displayed on the page. This is a basic test to ensure your application is working correctly.

To access your application, you'll need to use the specified URL and port. In this case, it's http://localhost:8000.

FastAPI doesn't provide its own HTML rendering templates, but we can integrate a template engine very seamlessly.

The two most popular template rendering libraries for FastAPI are Jinja and Mako, and Jinja is a common choice.

We can write our HTML templates in the templates/hello.html directory, where we can create the HTML template for FastAPI.

FastAPI templates can be integrated with static files, which include CSS style sheets.

For this, we need to make little changes in the HTML templates, using the url_for() function to link to a CSS file at static/styles.css.

If-Else in Templates is a straightforward process in FastAPI. You can add an "if-else" statement to your Jinja template by including it in your main.py file and passing necessary variables from your FastAPI route.

To integrate an if-else condition with your Jinja template, you can include it in your index.html file and pass the necessary variables from your FastAPI route. This allows you to render different content depending on the value of a variable.

You can add a message variable in the "read_root" route and use it to determine which content to render in the if-else block. The output will be different content depending on the value of the message variable.

In the code, you've added a message variable in the "read_root" route, which is then used in the if-else block to render different content. This is a useful technique for handling different scenarios in your application.
