Guide

The devtools will track any query you make through Horizon after the tools are initialized with createDevTools. If the query ends with fetch() the devtools will display the result of that query. If watch() is used 🔄 will show next to the query and be live updated with the results.

⌃ + Q will show/hide the devtools.

⌃ + W will change the position of the devtools.

You can run custom queries using the query editor in the devtools. Type in a query into the bottom text box and press ⌃ + Enter to run it. The horizon instance will be bound to horizon. If a query excludes fetch() or watch(), fetch() will be automatically appended. If a query excludes subscribe(), subscribe() will be automatically appended. For example, if horizon('users') is entered, horizon('users').fetch().subscribe() will be run.

API

`createDevTools(horizon): DevTools`

Attaches instrumentation for monitoring on the horizon instance. It returns a DevTools component hooked up to the instrumentation that automatically updates.

`<DevTools defaultVisible={true} defaultPosition='right' />`

This renders the developer tools into the window. If defaultVisible is set to false, the tools will not be open at first. defaultPosition can be either left, right, top, or bottom.
