Tracker: @deck.gl/json v2

Target Use Case

• Enable LLMs to generate deck.gl visualizations.
• Enable JSON schemas for editors like Monaco
• Add zod definitions to validate deck.gl JSON.
• Strengthen pydeck capabilities
• Better playground application
• ...

Proposal

Create a new module in deck.gl-community where we iterate and build a clean solution that we then propose for upstreaming into deck.gl/json

Details

• Move the expression parser in deck.gl to @math.gl/expressions
• Implement a catalog of Zod schemas for deck layer props, views etc.
• Generate JSON schemas for deck.gl JSON from the Zod schemas and publish/export them.
• Build out a playground v2 example in community repo that leverages all the features.
• Make the JSON LLM friendly, examples docs LLM.txt etc so that LLMs can easily generated correct deck.gl JSON.
• Provide a way to hook data sources into deck.gl/json, especially SQL sources (e.g. see the new SQLSourceLoader in upcoming loaders.gl v5.0 release)
• ...

This is a broad tracker with no files or tests named. Start by reviewing the existing deck.gl expression parser and the proposed SQLSourceLoader reference, then break the checklist into separately scoped tasks. Done requires an agreed community module plan covering schemas, generated JSON schemas, the playground, documentation, and data-source integration.
