## ERC20 Watcher
### Services
Create a postgres12 database and provide connection settings in `environments/local.toml`.
The default config files used by the watchers assume the following services are setup and running on localhost:
For example:
* `vulcanize/go-ethereum` on port 8545
* `vulcanize/ipld-eth-server` with native GQL API enabled, on port 8082
* `postgraphile` on the `vulcanize/ipld-eth-server` database, on port 5000
```
### Databases
Note: Requires `postgres12`.
Login as the postgres user:
```bash
sudo su - postgres
```
Create the databases for the watchers:
```
createdb erc20-watcher
createdb address-watcher
createdb uni-watcher
createdb uni-info-watcher
```
Update the `upstream` config in `environments/local.toml` and provide the `ipld-eth-server` GQL API and the `indexer-db` postgraphile endpoints.
Create the databases for the job queues and enable the `pgcrypto` extension on them (https://github.com/timgit/pg-boss/blob/master/docs/usage.md#intro):
Run the watcher:
```
createdb address-watcher-job-queue
createdb uni-watcher-job-queue
```
```
postgres@tesla:~$ psql -U postgres -h localhost address-watcher-job-queue

SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, bits: 256, compression: off)
Type "help" for help.
address-watcher-job-queue=# CREATE EXTENSION pgcrypto;
CREATE EXTENSION
address-watcher-job-queue=# exit
```
```

Type "help" for help.
uni-watcher-job-queue=# CREATE EXTENSION pgcrypto;
CREATE EXTENSION
uni-watcher-job-queue=# exit
```
## Run
To run any watcher, `cd` into their package folder and run:
```bash
cd packages/erc20-watcher
yarn run server
yarn server
```
GQL console: http://localhost:3001/graphql
To run tests (GQL queries) against the mock server:
```
cd packages/erc20-watcher
yarn run server:mock
```
If the watcher uses a job queue, start the job runner in another terminal:
```bash
cd packages/erc20-watcher
yarn test
```

## Scripts
To fill a block range:
* `yarn server`
```bash
$ yarn fill --startBlock <from-block> --endBlock <to-block>
```
Start the GraphQL server.
Example:
* `yarn watch:contract`
```bash
$ yarn fill --startBlock 1000 --endBlock 2000
```
Add contract to watch.
## Test
* `yarn lint`
To test the watchers locally:
Lint files.
* Deploy the Uniswap contracts
* Watch the Factory and NonFungiblePositionManager contracts
* Send transactions to trigger events
```bash
# Lint fix.
$ yarn lint --fix
```
