An example using pagefind to index a json file in rust.

First builds the pagefind index based off the data.json file.

cargo run

This should make a folder in /static/pagefind with the index files.

Then you can view the index.html file with reload.

npm install -g reload
reload -p --port 3000

Then open http://localhost:3000 in your browser. You will see that the search bar is using the data.json file to search for the data.
