39. "Add database connection pooling to a FastAPI app and explain how to tune pool size."
40. "Implement a job queue in FastAPI using Celery or RQ — enqueue a task, track its status, and fetch results."

Data Processing & AI

41. "Build a FastAPI app that accepts a CSV upload, processes it with pandas, and returns summary statistics as JSON."
42. "Create a FastAPI endpoint that runs a machine-learning model (pickle/onnx) and returns predictions."
43. "Add a text-summarization or sentiment-analysis endpoint to a FastAPI app using a Hugging Face model."
44. "Build a FastAPI app that generates embeddings and stores them in a vector database (pgvector) for similarity search."
45. "Create a FastAPI image-upload endpoint that resizes/compresses images with Pillow and stores them."

Templating & Frontend

46. "Build a FastAPI app with Jinja2 templates — a server-rendered multi-page site with a base layout."
47. "Add static files (CSS/JS/images) to a FastAPI app and wire them into Jinja templates."
48. "Create a FastAPI app that serves a single-page React build from a dist/ folder."

Error Handling & Middleware

49. "Add custom exception handlers to a FastAPI app — return structured JSON errors with proper HTTP codes."
50. "Build a FastAPI middleware that logs every request with method, path, status, and duration."
51. "Add request timing and a simple metrics endpoint (/metrics) exposing request counts and latencies."
52. "Implement a global exception handler that catches unhandled errors and returns a safe 500 response."

Real-World App Examples (Batch 2)

53. "Build a complete FastAPI blog — posts, comments, tags, and user authentication."

Navigating code on GitHub

You can understand the relationships within and across repositories by navigating code directly in GitHub.

About navigating code on GitHub

Code navigation helps you to read, navigate, and understand code by showing and linking definitions of a named entity corresponding to a reference to that entity, as well as references corresponding to an entity's definition.

Code navigation uses the open source tree-sitter library. The following languages support code navigation.

• Bash
• C
• C#
• C++
• CodeQL
• Elixir
• Go
• JSX
• Java
• JavaScript
• Lua
• PHP
• Protocol Buffers
• Python
• R
• Ruby
• Rust
• Scala
• Starlark
• Swift
• Typescript

You do not need to configure anything in your repository to enable code navigation. We will automatically extract code navigation information for these supported languages in all repositories.

GitHub has developed a code navigation approach based on the open source tree-sitter library that searches all definitions and references across a repository to find entities with a given name.

You can use keyboard shortcuts to navigate within a code file. For more information, see Keyboard shortcuts.

Using the symbols pane

You can now quickly view and navigate between symbols such as functions or classes in your code with the symbols pane. You can search for a symbol in a single file, in all files in a repository, or even in all public repositories on GitHub.

Symbol search is a feature of code search. For more information, see Understanding GitHub Code Search syntax.

1. Select a repository, then navigate to a file containing symbols.

2. To bring up the symbols pane, above the file content, click .

   Alternatively, you can open the symbols pane by clicking an eligible symbol in your file. Clickable symbols are highlighted in yellow when you hover over them.

3. Click the symbol you would like to find from the symbols pane or within the file itself.

   • To search for a symbol in the repository as a whole, in the symbols pane, click Search for this symbol in this repository. To search for a symbol in all repositories on GitHub, click all repositories.

4. To navigate between references to a symbol, click or .

5. To navigate to a specific reference to a symbol, click a result of the symbol search under In this file.

6. To exit the search for a specific symbol, click All Symbols.

Jumping to the definition of a function or method

You can jump to a function or method's definition within the same repository by clicking the function or method call in a file.

Finding all references of a function or method

You can find all references for a function or method within the same repository by clicking the function or method call in a file.

Troubleshooting code navigation

If code navigation is enabled for you but you don't see links to the definitions of functions and methods:

• Code navigation only works for active branches. Push to the branch and try again.
• Code navigation only works for repositories with fewer than 100,000 files.
