Description

Graph Node Dev Mode will make local subgraph development way easier. This mode will let devs iterate fast by watching file changes and auto-redeploying subgraphs no more messing around with IPFS or PostgreSQL config.

Goal

Let developers develop and deploy subgraphs locally with:

• No IPFS dependency
• No manual PostgreSQL setup ( Still need to install postgres )
• Super minimal configuration

Current Scope

• Add --watch flag to gnd
• When used:
  • Watches the build/ directory for any chanes
  • Auto redeploys the subgraph to local graph-node whenever files change
  • Shows the subgraph and GraphiQL URLs for immediate testing
• Subgraphs deploy straight from filesystem (no IPFS)
• Rebuilds still require manual triggering via gnd build
• Use pg_temp to:
  • Make a temporary Postgres instance inside build folder
  • Eliminate user database configuration

Tasks

• Create seperate graphnode-dev binary

  Refactor existing main function for reuse in new binary

  Make filesystem-based IPFS link resolver for subgraph deployment

  Add file watching code to trigger redeploys when files change

  Add logic to kill/restart node cleanly when files update

  Plug in pg_temp to auto provision temporary databases

  Support for Grafting

  Support for subgraph composition locally

  Implement build pipeline to build the new binary

  Graph CLI to install this binary

  Build filesystem-based IPFS client (for file data sources)

This will significantly improve the local development experience by removing configuration barriers.
