Manta-Network / manta-indexer

manta-indexer

Indexer is doing two things now:

1. Forwarding all rpc requests from Dapp.
2. Sync Utxo from manta node, so Dapp can get Utxo more quickly.

Indexer Design

Please take a look at indexer design if you're interested.

Perquisites

• rustc >= 1.58
• Sqlite >= 3.0
• yarn, nodejs >= 16.0

Deployment

1. Build the binary.

cargo b --profile production

2. Get and configure the config files. You should copy both folders conf and migrations to where you want to put. Please configure the config.toml

[indexer.configuration]
frequency = 2
rpc_method = "mantaPay_pull_ledger_diff"
full_node = "ws://127.0.0.1:9800"
port = 7788
prometheus_port = 7789

3. Run indexer.

./manta-indexer --config-path ./conf --migrations-path ./migrations

How to run tests

1. Setup a local relaychain network with polkadot-launch. You can use this json file to launch those nodes.
2. Start indexer.

cargo r

3. Run some typescript based test cases.

cd tests/integration-tests
yarn
yarn initialize-assets # configure public assets
yarn mint # mint some private assets for generating Utxos
yarn test-relayer

4. Run some rust based test cases by cargo. This step is based on step 3 due to some utxos generated by that steps.

cargo test
