Code Examples

Find real-world code examples across millions of public GitHub repositories using grep.app.

When to activate:

User wants to see real-world code examples
User asks "how do others implement X?"
User wants to find usage patterns for a library/API
User needs production code examples (not docs)

API endpoint:

curl -s "https://grep.app/api/search?q={query}&page=1" | jq '.hits.hits[:5]'

Parameters:

Parameter	Description
`q`	Search query (required)
`page`	Page number for pagination
`regexp`	`true` for regex search
`case`	`true` for case-sensitive
`f.lang`	Language filter (capitalized, e.g., `TypeScript` , `Go` , `Python` )
`f.repo.pattern`	Filter by repository pattern
`f.path.pattern`	Filter by file path pattern

Examples:

Search for useEffect usage in TypeScript:

curl -s "https://grep.app/api/search?q=useEffect&f.lang=TypeScript&page=1" | jq '.hits.hits[:3]'

Search for Go error handling patterns:

curl -s "https://grep.app/api/search?q=if%20err%20!=%20nil&f.lang=Go&page=1" | jq '.hits.hits[:3]'

Search within a specific repo:

curl -s "https://grep.app/api/search?q=createContext&f.repo.pattern=facebook/react&page=1" | jq '.hits.hits[:3]'

Response format:

```
hits.hits[]
```
- Array of search results
Each hit contains:
```
repo.raw
```
(repo name),
```
path.raw
```
(file path),
```
content.snippet
```
(code snippet)

Note: Returns max 1000 results. For documentation, use the documentation-lookup skill instead.
