Algebra Migration is an implementation of the Algebra Subgraph using the Squid SDK, migrating the Algebra subgraph to the squid SDK. It provides a powerful and flexible way to interact with on-chain data and query information from both EVM and WASM blockchains.
Before getting started, ensure you have the following dependencies installed on your machine:
- Node.js: JavaScript runtime for running JavaScript applications.
- Docker: Used to manage containers for PostgreSQL.
Follow these steps to set up and run Algebra migration on your local machine:
# 0. Install @subsquid/cli globally (the sqd command)
npm i -g @subsquid/cli
# 1. Clone the repository
git clone https://github.com/RicqCodes/Algebra_Subgraph_MIgration
# 2. Navigate to the project folder
cd Algebra_Subgraph_MIgration
# 3. Rename .env.example to .env and configure environment variables
# 4. Install project dependencies
npm i
# 5. Build the project
sqd build
# 6. Start a PostgreSQL database container and detach
sqd up
# 7. Run migrations
sqd migration:generate
sqd migration:run
# 8. Start the processor
sqd process
# 9. The processor command will block the terminal while fetching chain data,
# transforming it, and storing it in the target database.
# To start the GraphQL server, open a separate terminal and run
sqd serveA GraphiQL playground will be available at localhost:4350/graphql.
