# watcher-ts
|
|
|
|
## Setup
|
|
|
|
This project uses [yarn workspaces](https://classic.yarnpkg.com/en/docs/workspaces/).
|
|
|
|
Install packages (Node.JS v15.11.0):
|
|
|
|
```bash
|
|
yarn
|
|
```
|
|
|
|
### Services
|
|
|
|
The default config files used by the watchers assume the following services are setup and running on localhost:
|
|
|
|
* `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
|
|
|
|
#### Note
|
|
|
|
* In `vulcanize/ipld-eth-server`, add the following statement to `[ethereum]` section in `environments/config.toml`:
|
|
|
|
`chainConfig = "./chain.json" # ETH_CHAIN_CONFIG`
|
|
|
|
### 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
|
|
```
|
|
|
|
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):
|
|
|
|
```
|
|
createdb address-watcher-job-queue
|
|
createdb uni-watcher-job-queue
|
|
```
|
|
|
|
```
|
|
postgres@tesla:~$ psql -U postgres -h localhost address-watcher-job-queue
|
|
Password for user postgres:
|
|
psql (12.7 (Ubuntu 12.7-1.pgdg18.04+1))
|
|
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
|
|
```
|
|
|
|
```
|
|
postgres@tesla:~$ psql -U postgres -h localhost uni-watcher-job-queue
|
|
Password for user postgres:
|
|
psql (12.7 (Ubuntu 12.7-1.pgdg18.04+1))
|
|
SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, bits: 256, compression: off)
|
|
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
|
|
yarn server
|
|
```
|
|
|
|
If the watcher uses a job queue, start the job runner in another terminal:
|
|
|
|
```bash
|
|
yarn job-runner
|
|
```
