Web playground

[chrisberkhout]

I'll prototype this in the Mito repo and we can decide later where it should live.

Features

• Run the equivalent of mito -data state.json program.cel in the browser and inspect output
• Press a button for additional evaluations using state from the previous output
• Evaluation history
• Accumulation of events
• History organized into chains grouped by initial state and program version
• Sharing of a program and initial state
• Capture and inspection of HTTP requests and responses
• Sharing of full history and deep links to various items?
• Load program and state (keys, default values) from a CEL-input integration
• Provide state in JSON or YAML
• Generate a skeleton integration with input config based on a program and initial state

Approach

Compiling Mito to WASM would let everything run in the browser, as was done for the CEL and Beats playgrounds linked below.

I plan to begin using a server for running the Mito code and reevaluate when the UI is further along. A potential complication of full WASM is getting external requests working as intended.
