## 🏄 Get Started
This subgraph is deployed under `/subgraphs/name/oceanprotocol/ocean-subgraph/` namespace for all networks the Ocean Protocol contracts are deployed to:
- [subgraph.mainnet.oceanprotocol.com](https://subgraph.mainnet.oceanprotocol.com/subgraphs/name/oceanprotocol/ocean-subgraph/graphql)
- [subgraph.ropsten.oceanprotocol.com](https://subgraph.ropsten.oceanprotocol.com/subgraphs/name/oceanprotocol/ocean-subgraph/graphql)
- [subgraph.rinkeby.oceanprotocol.com](https://subgraph.rinkeby.oceanprotocol.com/subgraphs/name/oceanprotocol/ocean-subgraph/graphql)
- [subgraph.polygon.oceanprotocol.com](https://subgraph.polygon.oceanprotocol.com/subgraphs/name/oceanprotocol/ocean-subgraph/graphql)
- [subgraph.bsc.oceanprotocol.com](https://subgraph.bsc.oceanprotocol.com/subgraphs/name/oceanprotocol/ocean-subgraph/graphql)
## ⛵ Example Queries
**All pools**
```graphql
{
pools(orderBy: oceanReserve, orderDirection: desc) {
consumePrice
datatokenReserve
oceanReserve
spotPrice
swapFee
transactionCount
}
}
```
**All datatokens**
```graphql
{
datatokens(orderBy: createTime, orderDirection: desc) {
address
symbol
name
cap
supply
publisher
holderCount
}
}
```
**All pool transactions for a given user**
```graphql
{
poolTransactions(
where: { userAddressStr: $userAddress }
orderBy: timestamp
orderDirection: desc
) {
poolAddressStr
}
}
```
> Note: all ETH addresses like `$userAddress` in above example need to be passed in lowercase.
## 🏊 Development
First, clone the repo and install dependencies:
```bash
git clone https://github.com/oceanprotocol/ocean-subgraph/
cd ocean-subgraph
npm i
```
Developing and testing any change requires them to be deployed against a locally running graph-node and some other components running in Docker. Make sure you have Docker and Docker Compose installed on your machine, then prepare the Docker setup:
```bash
cd docker
./setup.sh
```
Then add your Infura key as environment variable with a `.env` file, and start everything up with Docker Compose:
```bash
# create .env and modify
cp .env.example .env
docker-compose --env-file .env up
```
The default network for development is set to Rinkeby. If you want to switch to another network you have to modify the `docker/docker-compose.yml` file within `environment.ethereum`.
You now have a local graph-node running and can start deploying your changes to it. To do so, follow the [Deployment instructions](#️-deployment).
## 🏊 Development on Barge
1. Clone [barge](https://github.com/oceanprotocol/barge) and run it in another terminal:
```bash
git clone https://github.com/oceanprotocol/barge.git
cd barge
./start_ocean.sh --with-thegraph
```
If you have cloned Barge previously, make sure you are using the latest version by running `git pull`.
2. Switch back to your main terminal and clone the repo and install dependencies:
```bash
git clone https://github.com/oceanprotocol/ocean-subgraph/
cd ocean-subgraph
npm i
```
3. If you use barge, then let the components know where to pickup the smart contract addresses. For production networks, skip this step
```
export ADDRESS_FILE="${HOME}/.ocean/ocean-contracts/artifacts/address.json"
```
4. Generate the subgraphs
```bash
node ./scripts/generatenetworkssubgraphs.js
npm run codegen
```
To generate subgraph for just one network, add the network name as parameter
```bash
node ./scripts/generatenetworkssubgraphs.js rinkeby
```
5. To deploy a subgraph use:
npm run create:local-[network]
npm run deploy:local-[network]
```bash
npm run create:local-development
npm run deploy:local-development
```
- Alternatively, if you want to get the sub-graph quickly running on barge, you can run `npm run quickstart:barge` which combines steps 3-5 above.
You now have a local graph-node running on http://127.0.0.1:9000/subgraphs/name/oceanprotocol/ocean-subgraph/graphql
## 🔍 Testing
- Please note: the `npm run test` command is currently not working due to [this issue](https://github.com/graphprotocol/graph-ts/issues/113).
To run the integration tests locally, first start up barge by following the instructions above, then run the following terminal commands from the ocean-subgraph folder:
```Bash
export ADDRESS_FILE="${HOME}/.ocean/ocean-contracts/artifacts/address.json"
npm run test-integration
```
## ✨ Code Style
For linting and auto-formatting you can use from the root of the project:
```bash
# lint all js with eslint
npm run lint
# auto format all js & css with prettier, taking all configs into account
npm run format
```
## 🛳 Releases
Releases are managed semi-automatically. They are always manually triggered from a developer's
machine with release scripts. From a clean `main` branch you can run the release task bumping
the version accordingly based on semantic versioning:
```bash
npm run release
```
The task does the following:
- bumps the project version in `package.json`, `package-lock.json`
- auto-generates and updates the CHANGELOG.md file from commit messages
- creates a Git tag
- commits and pushes everything
- creates a GitHub release with commit messages as description
- Git tag push will trigger Travis to do a npm release
For the GitHub releases steps a GitHub personal access token, exported as `GITHUB_TOKEN` is required. [Setup](https://github.com/release-it/release-it#github-releases)
## ⬆️ Deployment
Do the following to deploy the ocean-subgraph to a graph-node running locally, pointed against `mainnet`:
```bash
npm run codegen
# deploy
npm run create:local
npm run deploy:local
```
To deploy a subgraph connected to Rinkeby or Ropsten test networks, use instead:
```bash
# Rinkeby
npm run create:local-rinkeby
npm run deploy:local-rinkeby
# Ropsten
npm run create:local-ropsten
npm run deploy:local-ropsten
```
You can edit the event handler code and then run `npm run deploy:local`, with some caveats:
- Running deploy will fail if the code has no changes
- Sometimes deploy will fail no matter what, in this case:
- Stop the docker-compose run (`docker-compose down` or Ctrl+C)
This should stop the graph-node, ipfs and postgres containers
- Delete the `ipfs` and `postgres` folders in `/docker/data` (`rm -rf ./docker/data/*`)
- Run `docker-compose up` to restart graph-node, ipfs and postgres
- Run `npm run create:local` to create the ocean-subgraph
- Run `npm run deploy:local` to deploy the ocean-subgraph
> To deploy to one of the remote nodes run by Ocean, you can do port-forwarding and the above `:local` commands will work as is.
