**Use the GitHub web UI, `git ls-files`, `ripgrep`, or the `glob` utility to quickly locate any file in OmniRoute's monorepo structure.**

OmniRoute is a large TypeScript monorepo spanning Next.js API routes, SSE handlers, database modules, and an Electron desktop client. Because code is distributed across multiple top-level directories, knowing how to efficiently search the codebase is essential for developers working with `diegosouzapw/OmniRoute`.

## Method 1: GitHub Web Interface for Quick File Lookups

The fastest way to find a file when you know its approximate location is GitHub's built-in file browser.

Navigate to the release branch:

```

https://github.com/diegosouzapw/OmniRoute/tree/release/v3.8.50

```

Use the **"Search all files"** button (keyboard shortcut `t`) to filter the file tree in real time. This works best when you remember part of the filename or path.

## Method 2: GitHub Global Search for Partial Matches

When you only know a fragment of a filename or need to find symbols across the entire repository, use GitHub's global search.

**Search syntax for filenames:**

```

filename:route.ts path:/src/app/api/v1/chat

```

**Direct URL example:**

```

https://github.com/diegosouzapw/OmniRoute/search?q=filename:route.ts+path:/src/app/api/v1/chat

```

This returns direct links to matching files, including:
- [`src/app/api/v1/chat/completions/route.ts`](https://github.com/diegosouzapw/OmniRoute/blob/main/src/app/api/v1/chat/completions/route.ts)
- [`src/app/api/v1/chat/route.ts`](https://github.com/diegosouzapw/OmniRoute/blob/main/src/app/api/v1/chat/route.ts)

## Method 3: `git ls-files` for Local Repository Navigation

For deterministic, scriptable file discovery in a local clone, use Git's plumbing command.

**Basic pattern matching:**

```bash
git ls-files | grep 'chat.*route\.ts$'

```

**Exact path verification:**

```bash
git ls-files | grep '^src/app/api/v1/chat/completions/route\.ts$'

```

Output:

```

src/app/api/v1/chat/completions/route.ts

```

This method guarantees you only see **tracked files**, ignoring build artifacts and `node_modules`.

## Method 4: Node `glob` for Programmatic File Discovery

When building tools or tests that need to discover files dynamically, use the `glob` package.

```js
// find-files.js
// Run with: node find-files.js <pattern>
import { promisify } from 'node:util';
import { glob } from 'glob';

const pattern = process.argv[2] || '**/*.ts';
const cwd = process.cwd();               // repo root
const options = { cwd, absolute: true };

promisify(glob)(pattern, options)
  .then(files => {
    console.log(`Found ${files.length} files matching "${pattern}":`);
    files.forEach(f => console.log(f));
  })
  .catch(err => console.error('Glob error:', err));

```

**Example usage:**

```bash
$ node find-files.js "src/app/api/v1/chat/**/*.ts"

Found 3 files matching "src/app/api/v1/chat/**/*.ts":
/path/to/repo/src/app/api/v1/chat/completions/route.ts
/path/to/repo/src/app/api/v1/chat/route.ts
/path/to/repo/src/app/api/v1/chatgpt-web/image/[id]/route.ts

```

Install with: `npm i -D glob`

## Method 5: `ripgrep` for Content-Based File Discovery

When searching for function names, symbols, or code patterns rather than filenames, `ripgrep` (`rg`) is the optimal tool.

**Find all occurrences of a function:**

```bash
rg -n 'handleChatCore' src/

```

**Sample output:**

```

src/open-sse/handlers/chatCore.ts:1330:  export async function handleChatCore(...)
src/app/api/v1/chat/completions/route.ts:42:  const { handleChatCore } = await import(...)

```

**Key advantages over standard `grep`:**
- Respects `.gitignore` automatically
- Recurses directories by default
- Colorized output with line numbers
- Significantly faster on large codebases

VS Code's search panel uses `ripgrep` under the hood, providing the same functionality with a GUI.

## Method 6: Repository Map Documentation for High-Level Navigation

Before diving into file searches, consult the architectural overview.

**Critical reference file:** [`docs/architecture/REPOSITORY_MAP.md`](https://github.com/diegosouzapw/OmniRoute/blob/main/docs/architecture/REPOSITORY_MAP.md)

This document maps top-level directories to their purposes:

| Directory | Purpose |
|-----------|---------|
| `src/app/api/v1/` | Next.js API routes for LLM providers |
| `open-sse/` | SSE-based request handlers and routing engine |
| `src/lib/db/` | Database modules using `better-sqlite3` |
| `electron/` | Desktop client main process and IPC |
| `open-sse/mcp-server/` | MCP tool definitions (104 tools) |

Starting with the repository map prevents wasted time searching the wrong directory structure.

## Recommended Workflow for Finding Files

1. **Identify the component** — API route, SSE handler, DB module, or Electron code
2. **Check [`REPOSITORY_MAP.md`](https://github.com/diegosouzapw/OmniRoute/blob/main/REPOSITORY_MAP.md)** to narrow the directory scope
3. **Search by filename** using GitHub UI or `git ls-files`
4. **Refine with content search** (`rg`) if names are ambiguous
5. **Open directly** via GitHub link or local editor

## Summary

- **GitHub web UI** — fastest for known paths with `t` shortcut
- **GitHub global search** — best for partial filename matches across the repository
- **`git ls-files`** — deterministic, scriptable, shows only tracked files
- **Node `glob`** — programmatic discovery for build tools and tests
- **`ripgrep`** — superior speed for finding symbols and code patterns
- **[`REPOSITORY_MAP.md`](https://github.com/diegosouzapw/OmniRoute/blob/main/REPOSITORY_MAP.md)** — essential first stop for understanding directory structure

Combining the high-level repository map with precise filename or content searches reliably locates any code in the OmniRoute codebase.

## Frequently Asked Questions

### How do I find which file contains a specific function in OmniRoute?

Use `ripgrep` with the function name: `rg -n 'functionName' src/`. This searches file contents and returns the file path with line numbers. For the `handleChatCore` function, this reveals it's defined in [`open-sse/handlers/chatCore.ts`](https://github.com/diegosouzapw/OmniRoute/blob/main/open-sse/handlers/chatCore.ts) at line 1330 and imported in [`src/app/api/v1/chat/completions/route.ts`](https://github.com/diegosouzapw/OmniRoute/blob/main/src/app/api/v1/chat/completions/route.ts) at line 42.

### Where is the main API route for chat completions located?

The primary chat completions route is [`src/app/api/v1/chat/completions/route.ts`](https://github.com/diegosouzapw/OmniRoute/blob/main/src/app/api/v1/chat/completions/route.ts). Provider-specific variants exist at `src/app/api/v1/providers/[provider]/chat/completions/route.ts`. Both are reachable via the GitHub file browser or by searching `filename:route.ts path:/chat`.

### How can I list all TypeScript files in the OpenSSE directory programmatically?

Use the Node `glob` utility with pattern `open-sse/**/*.ts`. The provided [`find-files.js`](https://github.com/diegosouzapw/OmniRoute/blob/main/find-files.js) script demonstrates this: run `node find-files.js "open-sse/**/*.ts"` to get absolute paths to all TypeScript files in that directory tree.

### What is the best way to understand OmniRoute's directory structure?

Start with [`docs/architecture/REPOSITORY_MAP.md`](https://github.com/diegosouzapw/OmniRoute/blob/main/docs/architecture/REPOSITORY_MAP.md). This file documents the purpose of each top-level directory, distinguishing between API routes (`src/app/api/v1/`), SSE handlers (`open-sse/handlers/`), database code (`src/lib/db/`), and the Electron client (`electron/`).
