indexer-agent

Install Indexer Service & Agent

Set npm to use The Graph's private package registry. I recommend not using yarn, as it's caused me authentication issues in the past with Verdaccio.

# Don't use yarn
npm set registry https://testnet.thegraph.com/npm-registry
npm login

Install the CLI tools and revert your registry back to the original.

# Install the latest
npm install -g @graphprotocol/indexer-cli
npm install -g @graphprotocol/indexer-agent
npm install -g @graphprotocol/indexer-service # optional

npm set registry https://registry.npmjs.com/
