near-contract-helper

Microservice used to create NEAR accounts

Local Development

Requirements

Install latest Node.js LTS release

Install dependencies

yarn

Create database

Make sure you have PostgreSQL installed and running. On macOS, you can use Postgres.app.

Create accounts_development Postgres DB with helper user/password. You can do this from within psql using:

create user helper with superuser password 'helper';
create database accounts_development with owner=helper;

After that:

yarn migrate

You can also modify DB config in config/config.js to use different connection settings, etc.

Adding Migrations

Follow existing migrations as examples. To generate a migration file use the following:

npx sequelize-cli migration:generate --name migration-skeleton

Environment Variables

Create a .env file, copy in the default values from .env.sample. Read this file for information about how to change configuration settings to suit your needs.

By default, it assumes that you're running a local node and local network. To do this, use nearup or rainbow-bridge-cli

Now you can add an ACCOUNT_CREATOR_KEY to your .env. Running a local NEAR network created a ~/.near/localnet/node0/validator_key.json file for you. Copy the contents of this file and paste them as a single line, with NO whitespace, for the ACCOUNT_CREATOR_KEY value in your .env. For example:

ACCOUNT_CREATOR_KEY={"account_id":"node0","public_key":"...","secret_key":"..."}

Run server

yarn start

Create account (works only on test networks)

curl -H "Content-Type: application/json" -XPOST http://0.0.0.0:3000/account --data '{"newAccountId": "nosuchuseryet", "newAccountPublicKey": "22skMptHjFWNyuEWY22ftn2AbLPSYpmYwGJRGwpNHbTV"}

Lookup account by public key

curl -XGET http://0.0.0.0:3000/publicKey/ed25519:EKveJ28ocxfHXQEfH42AowPL7HgXHkKp3kmMoSXNjiRF/accounts
curl -XGET https://helper.mainnet.near.org/publicKey/ed25519:EKveJ28ocxfHXQEfH42AowPL7HgXHkKp3kmMoSXNjiRF/accounts

Sample response

[
    "heyheyhey.near"
]

Running tests

Create database

Follow the instructions above for creating the development database and helper user. Then create an accounts_test database using psql:

create database accounts_test with owner=helper;

Ensure NEAR localnet is running

As mentioned in the "Environment Variables" section above, make sure you are running a local blockchain

Run yarn test

This will run the tests using mocha. Assertions are written using chai with chai-as-promised for async assertions. Spies and fake timers provided with sinon.
