GraphQL API Server

• The fuel-indexer-api-server crate of the Fuel indexer contains a standalone GraphQL API server that acts as a queryable endpoint on top of the database.
• Note that the main fuel-indexer binary of the indexer project also contains a queryable GraphQL API endpoint.

The fuel-indexer-api-server crate offers a standalone GraphQL API endpoint, whereas the GraphQL endpoint offered in fuel-indexer is bundled with other Fuel indexer functionality (e.g., execution, handling, data-layer contruction, etc).

Usage

To run the standalone Fuel indexer GraphQL API server using a configuration file:

fuel-indexer-api-server run --config config.yaml

In the above example, config.yaml is based on the default service configuration file.
