Navigating Hasura

This page is only relevant when testing on a local machine or using a self-hosted version of Envio that uses Hasura.

Introduction​

This page explains how to navigate the Hasura dashboard, focusing on two key tabs: the API and Data tabs. These tabs allow you to interact with and view indexed results.

The screenshots provided below come from the Greeter tutorial.

API tab​

The API tab lets you execute GraphQL queries and mutations on indexed data. It serves as a GraphQL playground for testing your API calls.

/hasura-api-tab

Under the explorer, all entities defined in the schema.graphql file should appear. By default, Envio will also display dynamic_contracts and raw_events (raw_events doesn't get populated for Fuel indexers) that have been used in the indexing process.

In the GraphQL playground, you can structure and test your API calls using the indexed data.

For additional information on GraphQL queries, visit Hasura's quickstart guide.

Data tab​

The Data tab allows you to view and manage your database schema, tables, and relationships, providing crucial insight into the structure of the indexed data.

/hasura-data-tab

In the public schema, all indexed tables should appear. Again, by default, dynamic_contracts and raw_events tables will also be displayed.

To verify that the data has been correctly indexed, it is advisable to check the content of the entity tables and the db_write_timestamp values for the rows in each table.

Older db_write_timestamp values might signify stale data from a previous indexing run.
