Flask is an excellent framework for small to medium-sized web applications, and its simplicity, flexibility, and Pythonic design philosophy make it the first choice for many developers. However, for large and complex projects, some developers may opt for a larger and comprehensive framework such as Django. The choice of using Flask or another framework depends on the needs of the project and the preferences of the developer.
Lightweight:Flask's design philosophy is to keep it simple and have no mandatory dependencies. This makes it ideal for building small to medium-sized web apps, while also making for a relatively low learning curve.
Simple and easy to use:Flask's API is designed to be intuitive and quick for developers to get started. It only takes a few lines to create a basic web app.
Flexibility:Flask doesn't enforce the use of specific tools or libraries, and developers can choose the components that are appropriate for their project. This flexibility allows developers to customize the structure and functionality of their applications.
Routing system:Flask uses decorators to define routes, making the mapping between URLs and handlers intuitive. Such a routing system simplifies the handling and management of URLs.
Template Engine:Flask uses the Jinja2 templating engine, which allows developers to embed dynamic content in HTML pages. This increases the flexibility of the page while separating the application logic from the page rendering.
High level of integration:Flask has a large number of extensions that make it easy to integrate features such as databases, form processing, user authentication, and more. These extensions make it easy for developers to quickly build powerful web applications.
RESTful Support:Flask provides good support for building RESTful APIs. By using Flask's extensions or native features, developers can easily build APIs that conform to RESTful design principles.
Community Support:Flask has an active community with plenty of documentation, tutorials, and plugins. This makes it easy for developers to access help and resources.
pythonic：Flask follows Python's"pythonic"Philosophy that encourages conciseness and clarity. This makes it more natural for developers developing with Python to use Flask for web development.
Test Support:Flask provides testing tools and test clients to allow developers to write and run a variety of test cases, such as unit tests, integration tests, and more.
