yarn
Services
The default config files used by the watchers assume the following services are setup and running on localhost:
vulcanize/go-ethereumon port 8545vulcanize/ipld-eth-serverwith native GQL API enabled, on port 8082postgraphileon thevulcanize/ipld-eth-serverdatabase, on port 5000

vulcanize/ipld-eth-server, add the following statement to[ethereum]section inenvironments/config.toml:chainConfig = "./chain.json" # ETH_CHAIN_CONFIG
Databases
Note: Requires postgres12.
Login as the postgres user:
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 erc20-watcher-job-queue
createdb address-watcher-job-queue
createdb uni-watcher-job-queue
createdb uni-info-watcher-job-queue

Reset
Reset the databases used by the watchers:
yarn db:reset
Run
Build the files in packages:
yarn build
# To watch for changes and build (used in development).
yarn build:watch
To run any watcher, cd into their package folder and run:
yarn server
If the watcher uses a job queue, start the job runner in another terminal:
yarn job-runner
