Verifier server API implementation

You can run the verifier api service on 3 different sources:

• BTC / testBTC
• XRP / testXRP
• DOGE / testDOGE

For the api to work properly the service must be connected to the appropriate underlying postgresql database that is being filled with the the aproriate indexing solution (BTC indexer -> BTC api service)

Local Installation

Make sure you are using the node version specified in .nvmrc file. We recommend that you use nvm to manage local node installations. Make sure to use/enable yarn

Install the dependencies

$ yarn install

Running the app

# development
$ yarn run start

# watch mode
$ yarn run start:dev

Test

# unit tests
$ yarn run test

# e2e tests
$ yarn run test:e2e

# test coverage
$ yarn run test:cov

Testing with postgresql dump

Get db instances from some persistent storage, or ask other devs.

Move those db dumps to /e2e_tests/db/.

For now all dbs are on testnets.

Option1: running tests against db instance

Depending on your source, use the following command (btc example) yarn test:btc.

Option2: spinning up db from dumpb and persist it

Again depending on your source create db instance yarn test:make_db:btc, after that db will be available and you can

1. run tests against it, to do so use yarn test:run_tests:btc,
2. start up local server and make requests by hand.

In the second case set env variables of db to

# .env file
DB_DATABASE=db
DB_USERNAME=user
DB_PASSWORD=pass
DB_HOST=127.0.0.1
DB_PORT=8080

and specify the right values for VERIFIER_TYPE and TESTNET=true variables.

After you are done make sure to stop the db server with yarn test:delete_db.
