Sui indexer is an off-fullnode service to serve data from Sui protocol, including both data directly generated from chain and derivative data.

Architecture

enhanced_FN

Steps to run locally

Prerequisites

  • install local Postgres server. You can also brew install postgres@version and then add the following to your ~/.zshrc or ~/.zprofile, etc:
export LDFLAGS="-L/opt/homebrew/opt/postgresql@15/lib"
export CPPFLAGS="-I/opt/homebrew/opt/postgresql@15/include"
export PATH="/opt/homebrew/opt/postgresql@15/bin:$PATH"

  • make sure you have libpq installed: brew install libpq, and in your profile, add export PATH="/opt/homebrew/opt/libpq/bin:$PATH". If this doesn't work, try brew link --force libpq.

  • install Diesel CLI with cargo install diesel_cli --no-default-features --features postgres, refer to Diesel Getting Started guide for more details

  • [optional but handy] Postgres client like Postico, for local check, query execution etc.

Local Development(Recommended)

Use sui-test-validator

Running standalone indexer

  1. DB setup, under sui/crates/sui-indexer run:
# an example DATABASE_URL is "postgres://postgres:postgres@localhost/gegao"
diesel setup --database-url="<DATABASE_URL>"
diesel migration run --database-url="<DATABASE_URL>"

Note that you'll need an existing database for the above to work. Replace gegao with the name of the database created.

  1. Checkout to your target branch

For example, if you want to be on the DevNet branch

git fetch upstream devnet && git reset --hard upstream/devnet
  1. Start indexer binary, under sui/crates/sui-indexer run:
# Change the RPC_CLIENT_URL to http://0.0.0.0:9000 to run indexer against local validator & fullnode
cargo run --bin sui-indexer -- --db-url "<DATABASE_URL>" --rpc-client-url "https://fullnode.devnet.sui.io:443"

DB reset in case of restarting indexer

diesel database reset --database-url="<DATABASE_URL>"

Integration test

Integration tests in the integration_tests.rs will be run by GitHub action as part of the CI checks to run the test locally, start a Postgresql DB and run the test using following command:

POSTGRES_PORT=5432 cargo test --package sui-indexer --test integration_tests --features pg_integration

If you run into an error like DatabaseError(UniqueViolation, "duplicate key value violates unique constraint \"pg_proc_proname_args_nsp_index\""))' you can try running each integration test individually with

POSTGRES_PORT=5432 cargo test --package sui-indexer --test integration_tests --features pg_integration -- --test-threads=1

And to execute a single test such as just test_event_query_e2e, you can do

POSTGRES_PORT=5432 cargo test test_event_query_e2e --package sui-indexer --test integration_tests --features pg_integration -- --test-threads=1

Note all existing data will be wiped during the test.
