Anvil is a framework for building full stack web applications, including the user interface, server logic, and browser code, entirely in Python.
The typical web stack forces data through multiple transformations, from SQL to server-side objects, JSON, client-side objects, and finally HTML, creating unnecessary complexity.
The convoluted and magic-filled layers of web frameworks contradict core Python principles like simplicity and having one obvious way to do things.
Anvil simplifies web development by replacing the entire complex stack with a single Python-based abstraction for the UI, server, and database.
A step-by-step demonstration shows how to build and deploy a complete web application with a user interface, server functions, and a database using only Python in the Anvil IDE.
Anvil uses the open-source Sculpt compiler to translate Python into JavaScript, which is modified to handle blocking operations idiomatically for a smoother developer experience.
Anvil uses remote procedure calls with portable classes to pass Python objects between client and server, secured by a capability model that grants permissions implicitly.
Anvil's code completion system uses the Sculpt parser to analyze the abstract syntax tree in real-time, providing context-aware suggestions across the client, server, and database.
The framework is guided by two principles: embracing code as the best way to instruct a computer and ensuring accessibility for both beginners and seasoned professionals.
The speaker answers audience questions about security models that prevent SQL injection, integrating external APIs, handling complex database queries, and runtime performance.
