FRAMEWORK, INDUSTRY and TERM are the facets exposed by the /api/v1/* REST resources; page, section and embedding are the core SurrealDB tables.

Quick Start (≤ 5 minutes)

Fastest path — nothing to install: use the live site and the open API.

Run a local copy:

bash
git clone https://github.com/simonmak-ascent/esg-hub.git
cd esg-hub
pnpm install        # note: requires sibling repo ../tool_package (private)
cp .env.example .env  # fill in your own values
pnpm dev

Useful commands: pnpm lint · npx tsc --noEmit · npx vitest run · pnpm verify:db

Note: the app renders content from a SurrealDB database — you need your own instance and content to run a full copy. The public site and API are freely accessible without running anything.

API & MCP

  • REST API: open, no auth — GET /api/v1/pages, /api/v1/search?q=..., /api/v1/resources, /api/v1/meta (docs)
  • MCP server: see mcp-server/ — gives AI agents tools to search and read the knowledge base
