## ⚠️ LSP Configuration and Environment Variable Limitations
|
||
|
||
**Warning: Pre-built Image LSP Configuration Limitations**
|
||
|
||
The pre-built Docker image `cfngc4594/monaco-editor-lsp-next` is configured to connect exclusively to `ws://localhost:4594/clangd` and `ws://localhost:4595/clangd`. This is due to the LSP configuration being set via `NEXT_PUBLIC` environment variables during the image build process.
|
||
|
||
* **Build-Time Freezing:** As per the Next.js [official documentation](https://nextjs.org/docs/pages/building-your-application/configuring/environment-variables#bundling-environment-variables-for-the-browser), `NEXT_PUBLIC` variables are frozen at build time, and subsequent changes are ineffective.
|
||
* **Local LSP Server Dependency:** Therefore, the pre-built image can only connect to the specified local LSP servers.
|
||
* **Custom Configuration Requirement:** If you wish to define your own LSP configuration via environment variables, you **cannot** use the pre-built image. Instead, you must:
|
||
* Clone the source code.
|
||
* Set your desired environment variables.
|
||
* Manually build the Docker image.
|
||
|
||
**Upcoming Improvements (v0.0.1):**
|
||
|
||
To address these limitations, v0.0.1 will implement the officially recommended API approach for retrieving LSP configurations, enabling runtime dynamic LSP server configuration without image rebuilding.
|
||
|
||
## ⚠️ WSL Users: Critical Configuration
|
||
|
||
### 🐧 Network Mode Requirement
|
||
|
||
When using Windows Subsystem for Linux (WSL), you **must** configure your network mode as **Mirrored** to ensure proper LSP server connectivity. Standard WSL network configurations may create IPv6 conflicts that block Monaco-LSP communication.
|
||
|
||
#### 🔧 Mirror Mode Setup:
|
||
|
||
1. Open WSL settings ⚙️
|
||
2. Navigate to **Network** section 🌐
|
||
3. Select **Mirrored** mode 🔄
|
||
4. Restart WSL instance 💻
|
||
|
||
Complete these steps before launching the editor for seamless LSP integration! 🎉
|
||
|
||
## 🚀 Getting Started
|
||
|
||
### 🐳 Docker Deployment (Recommended)
|
||
|
||
Deploy the project quickly using pre-built Docker images:
|
||
|
||
```sh
|
||
# Clone the repository
|
||
git clone https://github.com/cfngc4594/monaco-editor-lsp-next
|
||
cd monaco-editor-lsp-next
|
||
|
||
# Start the application with pre-built images
|
||
docker compose up -d
|
||
```
|
||
|
||
### 🔨 Local Manual Build
|
||
|
||
Build the images locally and start the containers:
|
||
|
||
```sh
|
||
# Clone the repository
|
||
git clone https://github.com/cfngc4594/monaco-editor-lsp-next
|
||
cd monaco-editor-lsp-next
|
||
|
||
# Build and start containers using the local configuration
|
||
docker compose -f compose.local.yml up -d --build
|
||
```
|
||
|
||
### 🛠 Development Mode
|
||
|
||
Set up a development environment with hot-reloading:
|
||
|
||
```sh
|
||
# Clone the repository
|
||
git clone https://github.com/cfngc4594/monaco-editor-lsp-next
|
||
cd monaco-editor-lsp-next
|
||
|
||
# Start only the LSP containers
|
||
docker compose up -d lsp-c lsp-cpp
|
||
# Or use the local configuration
|
||
# docker compose -f compose.local.yml up -d --build lsp-c lsp-cpp
|
||
|
||
# Install dependencies and start the development server
|
||
bun install
|
||
bun run dev
|
||
```
|
||
|
||
## ⚙️ Technical Configuration
|
||
|
||
### LSP Server Mapping
|
||
|
||
| **Language** | **LSP Server** | **Port** |
|
||
|--------------|----------------|----------|
|
||
| `C` | `clangd` | `4594` |
|
||
| `C++` | `clangd` | `4595` |
|
||
|
||
## 📦 Dependency Management
|
||
|
||
### 🔒 Version Lock Requirements
|
||
|
||
**Critical Pairing**:
|
||
| Package | Max Version | Reference |
|
||
|-------------------------|-------------|-----------|
|
||
| `monaco-editor` | ≤0.36.1 | [Compatibility Matrix](https://github.com/TypeFox/monaco-languageclient/blob/main/docs/versions-and-history.md#monaco-editor--codingamemonaco-vscode-api-compatibility-table) |
|
||
| `monaco-languageclient` | ≤5.0.1 | |
|
||
|
||
**Version Lock Rationale**:
|
||
1. **API Stability**
|
||
- Newer `monaco-editor` (≥0.40.0) breaks `monaco-languageclient` integration
|
||
- v0.36.1 matches `@codingame/monaco-vscode-api@1.76.9` requirements
|
||
|
||
2. **LSP Feature Breakdown**
|
||
- Version mismatches disable:
|
||
- Auto `textDocument/didOpen` events
|
||
- `textDocument/inlayHint` resolution
|
||
- `textDocument/documentLink` functionality
|
||
|
||
3. **Version Conflict**
|
||
- `@codingame` package versioning (e.g., `11.1.2`) ≠ `monaco-editor` versions (e.g., `0.36.1`)
|
||
- `@monaco-editor/react` depends on `monaco-editor` versioning scheme
|
||
|
||
**Failure Indicators**:
|
||
- ✔️ WebSocket connection established
|
||
- ❌ Missing syntax highlighting
|
||
- ❌ No autocomplete suggestions
|
||
- ❌ Silent LSP initialization failures
|
||
|
||
### 🎨 Shiki Compatibility Notice
|
||
|
||
Syntax highlighting depends on `rehype-pretty-code`'s deprecated `getHighlighter` API from `shiki@legacy`.
|
||
|
||
**Key Points**:
|
||
|
||
- **Affected File:** `src/components/mdx-preview.tsx`
|
||
- **Dependency Chain:** `rehype-pretty-code` → `shiki@legacy`
|
||
- **Version Constraints**:
|
||
|
||
```sh
|
||
"shiki": "<=2.5.0"
|
||
"@shikijs/monaco": "<=2.5.0"
|
||
```
|
||
|
||
**Maintenance Note**:
|
||
While `shiki@3.0.0+` introduces modern APIs (`createHighlighter`/`getSingletonHighlighter`), upgrading requires `rehype-pretty-code` updates. Track progress [here](https://github.com/atomiks/rehype-pretty-code).
