* In the [config file](./environments/local.toml):
* Update the database connection settings.
* Update the `upstream` config and provide the `ipld-eth-server` GQL API endpoint.
* Update the `server` config with state checkpoint settings and provide the IPFS API address.
## Customize
* Indexing on an event:
* Edit the custom hook function `handleEvent` (triggered on an event) in [hooks.ts](./src/hooks.ts) to perform corresponding indexing using the `Indexer` object.
* While using the indexer storage methods for indexing, pass `diff` as true if default state is desired to be generated using the state variables being indexed.
* Generating state:
* Edit the custom hook function `createInitialState` (triggered if the watcher passes the start block, checkpoint: `true`) in [hooks.ts](./src/hooks.ts) to save an initial state `IPLDBlock` using the `Indexer` object.
* Edit the custom hook function `createStateDiff` (triggered on a block) in [hooks.ts](./src/hooks.ts) to save the state in a `diff``IPLDBlock` using the `Indexer` object. The default state (if exists) is updated.
* Edit the custom hook function `createStateCheckpoint` (triggered just before default and CLI checkpoint) in [hooks.ts](./src/hooks.ts) to save the state in a `checkpoint``IPLDBlock` using the `Indexer` object.
