# Required HTTP Bridge Endpoints for EA Development
The Windows HTTP bridge needs these additional endpoints for EA development:
## 1. EA Upload Endpoint
```
POST /api/ea/upload
Content-Type: application/json
{
"ea_name": "MyEA",
"ea_content": "//+------------------------------------------------------------------+\n//| EA Source Code Here..."
}
Response:
{
"success": true,
"message": "EA uploaded successfully",
"file_path": "MQL4/Experts/MyEA.mq4"
}
```
## 2. EA Compilation Endpoint
```
POST /api/ea/compile
Content-Type: application/json
{
"ea_name": "MyEA"
}
Response:
{
"success": true,
"compiled": true,
"warnings": 0,
"errors": 0,
"log": "compilation output...",
"ex4_path": "MQL4/Experts/MyEA.ex4"
}
```
## 3. Implementation Notes
The HTTP bridge should:
1. **EA Upload**: Write .mq4 files to MT4's `MQL4/Experts/` directory
2. **EA Compilation**: Use MetaEditor command line to compile:
```cmd
metaeditor64.exe /compile:"C:\Path\To\MT4\MQL4\Experts\MyEA.mq4" /log
```
3. **Error Handling**: Parse compilation logs for errors/warnings
4. **File Management**: Ensure proper file permissions and paths
## 4. Example Implementation (Node.js)
```javascript
// EA Upload
app.post('/api/ea/upload', (req, res) => {
const { ea_name, ea_content } = req.body;
const filePath = path.join(MT4_EXPERTS_PATH, `${ea_name}.mq4`);
fs.writeFileSync(filePath, ea_content, 'utf8');
res.json({
success: true,
message: 'EA uploaded successfully',
file_path: filePath
});
});
// EA Compilation
app.post('/api/ea/compile', (req, res) => {
const { ea_name } = req.body;
const sourceFile = path.join(MT4_EXPERTS_PATH, `${ea_name}.mq4`);
// Use child_process to run MetaEditor
const { spawn } = require('child_process');
const compiler = spawn('metaeditor64.exe', [
`/compile:${sourceFile}`,
'/log'
]);
// Handle compilation output...
});
```
