Full Stack Local Deployment

Run the commands below from the top-level folder. Alternatively, it is possible to cd into the relevant package first and then call yarn without workspace @kleros/xxxx.

Shortcut using tmux

If you have tmux installed, you can get started quickly with a single command.

$ yarn local-stack

Shell 1 - Local RPC with Contracts Deployed

$ yarn workspace @kleros/kleros-v2-contracts start-local
...
Started HTTP and WebSocket JSON-RPC server at http://127.0.0.1:8545/

⏳ Wait until deployment is complete.

Shell 2 - Local Graph Node

$ yarn workspace @kleros/kleros-v2-subgraph start-local-indexer
...
graph-node-graph-node-1  | INFO Successfully connected to IPFS node at: http://ipfs:5001/
graph-node-graph-node-1  | INFO Pool successfully connected to Postgres, pool: main, shard: primary, component: Store

⏳ Wait until the graph service is ready.

Shell 3 - Subgraph Rebuild and Local Deploy

:warning: This step modifies subgraph.yaml and creates a backup file. See further down on how to restore it.

$ yarn workspace @kleros/kleros-v2-subgraph rebuild-deploy:local
...
✔ Upload subgraph to IPFS
