Local Development

Prerequisites

• Node.js 18+
• Mintlify CLI

Install Mintlify CLI

npm i -g mintlify

Start Local Preview

mintlify dev

View at http://localhost:3000

Updating OpenAPI Specs

The API Reference and Gateway Reference are generated from OpenAPI specifications. There are two methods to update them:

Method 1: Automatic (Recommended)

Fetches specs directly from running servers:

# Start the source servers first
cd ~/hummingbot-api && make run        # Starts at localhost:8000
cd ~/gateway && pnpm start --dev       # Starts at localhost:15888

# Generate and process specs
./scripts/generate-openapi.sh

# Or update only one:
./scripts/generate-openapi.sh --api-only
./scripts/generate-openapi.sh --gateway-only

Method 2: Manual

If you already have the OpenAPI JSON files:

1. Place files in openapi-sources/:

   • hummingbot-api.json - from http://localhost:8000/openapi.json
   • gateway.json - from http://localhost:15888/docs/json

2. Run the update script:

   ./scripts/update-openapi.sh

What the Scripts Do

1. Hummingbot API (api-reference/openapi.json):

   • Copied directly from source (no processing needed)
   • The API server already generates clean operationIds and summaries

2. Gateway (gateway-reference/openapi.json):

   • Processed by process-openapi.js which:
     • Adds operationId fields for clean URL paths
     • Adds summary fields for sidebar titles
     • Converts anyOf with null to nullable: true (Mintlify compatibility)

After Updating

1. Run mintlify dev to preview changes
2. Verify sidebar titles and URL paths look correct
3. Commit all changes including both openapi-sources/ and processed files

Troubleshooting

Dev server not starting

mintlify update  # Update CLI to latest version

404 on pages

Ensure you're running mintlify dev in the directory containing docs.json.

Gateway sidebar shows ugly URLs

Re-run ./scripts/generate-openapi.sh --gateway-only to regenerate with proper operationIds.

Publishing

Changes pushed to the main branch are automatically deployed via Mintlify's GitHub integration.
