+# [VSCODE web based](https://github.com/coder/code-server) with jupyter
+
+## Install vscode
+
+> Run in jupyter terminal
+
+```bash
+curl -fsSL https://code-server.dev/install.sh | sh
+```
+
+## Setting up server parameters
+
+> In the server config, you need to add the following lines.
+> This is necessary because to run such applications, jupyter-server-proxy is used, which uses **\_default_max_message_size** directly from the **tornado.websocket** module, and not from the **c.LabApp.tornado_settings** configuration. [websocket.py#L52](https://github.com/jupyterhub/jupyter-server-proxy/blob/76a98c900605e31a9209e0897d3010d2c6057960/jupyter_server_proxy/websocket.py#L52)
+
+**jupyter_lab_config.py**
+
+```py
+from tornado import websocket
+websocket_max_message_size = 1048 * 1024 * 1024
+# fix module
+setattr(websocket, "_default_max_message_size", websocket_max_message_size)
+# fix config
+c.LabApp.tornado_settings = {"websocket_max_message_size": websocket_max_message_size}
+```
+
+## Setting up jupyter_app_launcher with open in new TAB
+
+Open [juyter_app_launcher config file](https://jupyter-app-launcher.readthedocs.io/en/latest/usage.html#configuration-file-location)
+
+> Add application launch parameters
+
