ixo-blocksync

Syncs all the public info from an ixo blockchain to an instance of PostgreSQL. It gets fed from a ixo-blocksync-core database in order to speed up indexing and put less strain on nodes, which means you need an ixo-blocksync-core database connection in order to run this.

For now the only source for information is a ixo-blocksync-core database connection, but we plan on expanding that to different sources in the near future.

Run

From Source

Requirements

• PostgreSQL

git clone https://github.com/ixofoundation/ixo-blocksync.git
cd ixo-blocksync/

Copy .env.example to .env and configure. If this step is skipped, ixo-blocksync will use .env.example as the configuration by default.

• Create a database called Blocksync

yarn install
yarn build
yarn start

---

Using Docker (with Compose)

Requirements

• Docker
• Docker Compose

git clone https://github.com/ixofoundation/ixo-blocksync.git
cd ixo-blocksync/

Copy .env.example to .env and configure. If this step is skipped, ixo-blocksync will use .env.example as the configuration by default. Don't use quotations when asign env vars for docker
Delete the seed folder in src/seed/* if you do not plan to import data from json
Create a role(e.g. app_user) in the DB for postgress to work

docker build -t ixofoundation/ixo-blocksync:latest .
docker compose up -d

API interface

The server exposes a Graphql api endpoint at /graphql which is set up using Postgraphile along with some plugins:

• pg-simplify-inflector
• postgraphile-plugin-connection-filter
• pg-aggregates

A graphiql playground gets exposed at the endpoint /graphiql where you can play around, test queries and see the schemas.

We also generate and expose the full graphql schema file (schema.graphql) under the endpoint /api/graphql_schema if you need it to generate clients.
