Tree visualizer
You can use the tree-viz
tool in the tools
folder to visualize the outcome of the parser for a given TraceQL query.
Example:
Before using this tool, be sure you have already built the project, as described above.
To run the tool, you need to run a HTTP server first. For instance, you can do this by opening a terminal at the root folder and running:
npx http-server
This should start a HTTP server at http://127.0.0.1:8080
. You can now fetch the tools/tree-viz.html
page from the HTTP server: open your browser and visit http://127.0.0.1:8080/tools/tree-viz.html
.
