# Repository Guidelines
|
||||||
|
|
||||||
|
## Project Structure & Module Organization
|
||||||
|
This repository is a Vite + Vue 3 + TypeScript frontend app.
|
||||||
|
|
||||||
|
- `src/`: application source code
|
||||||
|
- `src/components/`: Vue UI components (for example, `MonacoEditor.vue`, `ThemeToggle.vue`)
|
||||||
|
- `src/api/`: HTTP client logic (`completion.ts`)
|
||||||
|
- `src/types/`: shared TypeScript interfaces for API payloads
|
||||||
|
- `public/`: static assets served as-is
|
||||||
|
- `dist/`: production build output (generated)
|
||||||
|
- `backend/`: placeholder folder; no active backend code is currently committed
|
||||||
|
|
||||||
|
Use the `@` alias for imports from `src` (configured in `vite.config.ts` and `tsconfig.app.json`).
|
||||||
|
|
||||||
|
## Build, Test, and Development Commands
|
||||||
|
- `npm install`: install dependencies.
|
||||||
|
- `npm run dev`: start local development server with HMR.
|
||||||
|
- `npm run build`: run type checks (`vue-tsc -b`) and build production assets.
|
||||||
|
- `npm run preview`: serve the built app locally for verification.
|
||||||
|
|
||||||
|
Current package scripts do not include linting or unit test commands.
|
||||||
|
|
||||||
|
## Coding Style & Naming Conventions
|
||||||
|
- Use Vue 3 Composition API with `<script setup lang="ts">`.
|
||||||
|
- Use TypeScript strict mode patterns; avoid `any` unless justified.
|
||||||
|
- Use 2-space indentation and single quotes, matching existing files.
|
||||||
|
- Name components in PascalCase (e.g., `MonacoEditor.vue`).
|
||||||
|
- Name composables/helpers and API modules in camelCase (e.g., `fetchCompletions`).
|
||||||
|
- Keep shared interfaces in `src/types/*` and colocate feature-specific logic where used.
|
||||||
|
|
||||||
|
## Testing Guidelines
|
||||||
|
No automated test framework is configured yet in `package.json`.
|
||||||
|
|
||||||
|
When adding tests, prefer Vitest + Vue Test Utils and place files as:
|
||||||
|
- `src/**/__tests__/*.spec.ts`
|
||||||
|
|
||||||
|
Minimum verification for every change:
|
||||||
|
1. `npm run build` succeeds.
|
||||||
|
2. `npm run dev` runs without console/runtime errors for the changed flow.
|
||||||
|
|
||||||
|
## Commit & Pull Request Guidelines
|
||||||
|
Git history is not available in this workspace snapshot, so no existing commit pattern can be inferred. Use Conventional Commits going forward:
|
||||||
|
- `feat: add completion request timeout`
|
||||||
|
- `fix: handle empty completion response`
|
||||||
|
|
||||||
|
PRs should include:
|
||||||
|
1. Clear summary of user-visible and technical changes.
|
||||||
|
2. Linked issue/task ID (if applicable).
|
||||||
|
3. Validation steps and commands run.
|
||||||
|
4. Screenshots or short recordings for UI changes.

# Monaco Go Completion Backend
|
||||||
|
|
||||||
|
Gin + gopls(JSON-RPC/LSP over stdio) 实现的 Go 代码补全后端。
|
||||||
|
|
||||||
|
## 运行
|
||||||
|
|
||||||
|
```bash
|
||||||
|
go mod tidy
|
||||||
|
go run ./cmd/server
|
||||||
|
```
|
||||||
|
|
||||||
|
默认监听 `http://localhost:8080`。
|
||||||
|
|
||||||
|
## 环境变量
|
||||||
|
|
||||||
|
- `PORT`：HTTP 端口，默认 `8080`
|
||||||
|
- `GOPLS_PATH`：`gopls` 可执行文件路径，默认 `gopls`
|
||||||
|
- `WORKSPACE_DIR`：gopls 工作目录，默认当前目录
|
||||||
|
- `CORS_ALLOW_ORIGIN`：CORS 允许来源，默认 `*`
|
||||||
|
|
||||||
|
## API
|
||||||
|
|
||||||
|
### 健康检查
|
||||||
|
|
||||||
|
- `GET /health`
|
||||||
|
|
||||||
|
### Go 补全
|
||||||
|
|
||||||
|
- `POST /api/v1/completions/go`
|
||||||
|
- `Content-Type: application/json`
|
||||||
|
|
||||||
|
### Go 补全（WebSocket）
|
||||||
|
|
||||||
|
- `GET /ws/completions/go`
|
||||||
|
- 客户端发送：
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"id": "1",
|
||||||
|
"uri": "file:///main.go",
|
||||||
|
"text": "package main\n\nimport \"fmt\"\n\nfunc main() {\n fmt.Pri\n}",
|
||||||
|
"line": 5,
|
||||||
|
"character": 11
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
- 服务端返回：
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"id": "1",
|
||||||
|
"items": [{ "label": "Println" }],
|
||||||
|
"isIncomplete": false
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
请求体：
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"uri": "file:///C:/Users/meowr/Desktop/bishe/monica_editor_with_code_completion/backend/playground.go",
|
||||||
|
"text": "package main\n\nimport \"fmt\"\n\nfunc main() {\n fmt.Pri\n}",
|
||||||
|
"line": 5,
|
||||||
|
"character": 11
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
说明：
|
||||||
|
- `uri` 建议使用绝对 `file://` URI（与 `WORKSPACE_DIR` 在同一工作区最稳定）。
|
||||||
|
- 也支持 `file:///main.go` 这类相对根路径 URI，后端会自动映射到 `WORKSPACE_DIR` 下。
|
||||||
|
- `line` / `character` 为 0-based。
|
||||||
|
- 每次请求都要传前端当前全文 `text`。
|
||||||
|
|
||||||
|
响应体：
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"items": [
|
||||||
|
{
|
||||||
|
"label": "Println",
|
||||||
|
"kind": 3,
|
||||||
|
"detail": "func(a ...any) (n int, err error)",
|
||||||
|
"documentation": "Println formats using the default formats..."
|
||||||
|
}
|
||||||
|
],
|
||||||
|
"isIncomplete": false
|
||||||
|
}
|
||||||
|
```
