JSON Schema for Crossbar.io Configuration File Format
We now have a JSON Schema file available for config.json, if you're using VSCode you can make use of this by adding the following to your VSCode settings; (File -> Preferences -> Settings)
"json.schemas": [
{
"fileMatch": [
"/config.json",
"/.config.json"
],
"url": "https://raw.githubusercontent.com/crossbario/crossbar/master/crossbar.json"
}
],
Alternatively, the generic approach is to insert a "$schema" line at the top of your file;
{
"$schema": "https://raw.githubusercontent.com/crossbario/crossbar/master/crossbar.json",
"version": 2,
This file is currently experimental, but it should give you contextual auto-completion on all Crossbar config.json syntax, use CTRL+Space in VSCode to activate IntelliSense.
