-## Debug
+## Debug xds-agent (Go code)
+
+Install first [Visual Studio Code](https://code.visualstudio.com/) and
+[Go plugin](https://marketplace.visualstudio.com/items?itemName=lukehoban.Go)
+(`ext install lukehoban.Go`)
Visual Studio Code launcher settings can be found into `.vscode/launch.json`.
+The important think is to correctly set `GOPATH` in launch.json in order to
+build xds-agent and debug it within Visual Studio Code.
+
+Here is an example of launch.json:
+
+```json
+{
+ "version": "0.2.0",
+ "configurations": [{
+ "name": "XDS-Agent",
+ "type": "go",
+ "request": "launch",
+ "mode": "debug",
+ "remotePath": "",
+ "port": 2345,
+ "host": "127.0.0.1",
+ "program": "${workspaceRoot}",
+ "env": {
+ "GOPATH": "${workspaceRoot}/../../../../../..:${env:GOPATH}",
+ },
+ "args": ["-log", "debug", "-c", "__agent-config_local_dev.json"],
+ "showLog": false
+ }
+ ]
+}
+```
+
+And `__agent-config_local_dev.json` file content is as follow :
+
+```json
+{
+ "webAppDir": "./webapp/dist",
+ "logsDir": "${HOME}/tmp/xds-agent/logs",
+ "xdsServers": [
+ {
+ "url": "http://localhost:8000"
+ }
+ ],
+ "syncthing": {
+ "binDir": "./bin",
+ "home": "${HOME}/tmp/xds_local_dev/syncthing-config",
+ "gui-address": "http://localhost:8386",
+ }
+}
+```

+### Tricks to debug both xds-agent and xds-server
->**Tricks:**
->
->To debug both `xds-agent` and `xds-server` or common code
->`xds-common`, it may be useful use the same local sources.
->
->So you should replace `xds-server` + `xds-common` in `vendor` directory by a symlink.

->So clone first `xds-server` + `xds-common` sources next to `xds-agent` directory.
+To debug both `xds-agent` and `xds-server` or common code `xds-common`, it may
+be useful use the same local sources.
+
+A trick to do that is to replace `xds-server` + `xds-common` in `vendor`
+directory by a symlink that points to local sources.
+
+So clone first `xds-server` + `xds-common` sources next to `xds-agent` directory.
You should have the following tree:
```bash
-tree -L 5 --charset=ascii src/
+tree -L 5 src/
src/
`-- gerrit.automotivelinux.org
`-- gerrit
`-- src
`-- xds
- |-- backup.sh
|-- xds-agent
- |-- xds-cli
|-- xds-common
- |-- xds-docs
- |-- xds-gdb
`-- xds-server
```
-Then invoke `vendor/debug` Makefile rule to create a symlink inside vendor
+Then invoke `vendor/debug` Makefile rule to create symbolic links inside vendor
directory :
```bash
cd src/gerrit.automotivelinux.org/gerrit/src/xds/xds-agent
make vendor/debug
```
+
+## Debug dashboard part (Typescript / angular code)
+
+Start `xds-agent` either from command line or in debug mode (see previous
+chapter) and in another terminal start a watcher daemon so that type typescript
+sources of webapp / dashboard are automatically "transpiled" using following
+command :
+
+```bash
+cd webapp
+npm run watch
+```
+
+Then open the XDS Dashboard page ([http://localhost:8800](http://localhost:8800))
+and open the developer tool of web browser (for example `Ctrl+Shift+I` in Chrome).
