Locksmith

Locksmith is a backend service that provides some services in the context of Unlock. None of these services are required to use the core-protocol. Among these services, locksmith provides the following:

• NFT metadata hosting
• membership metadata hosting
• Unlock accounts

The locksmith application has several entry points. By default it provides an API server, but could also be run for our worker worker. For the latter, prefix all commands with worker: (for example: yarn run worker:dev)

Getting Started

Configure Database

Locksmith uses postgres under the hood.

To start, you can spin up a local instance of postgres using docker by running docker run --name locksmith-postgres -p 5432:5432 -e POSTGRES_PASSWORD=postgres -e POSTGRES_USER=postgres -d postgres or go with a traditional install or hosting provider.

Configure environment variables (Locksmith will recognize these placed in an .env.dev.local file at the root of the monorepo)

If you used the docker command above, add: DATABASE_URL=postgresql://postgres:postgres@127.0.0.1:5432/postgres (you may need to replace the IP)

Alternatively, you could set these variables:

• DB_USERNAME - Database User
• DB_PASSWORD - Password of User
• DB_NAME - Database Name
• DB_HOSTNAME - Database Host

Configure file storage

Locksmith uses S3 to store various files. To configure this, you will need to set the following environment variables:

• STORAGE_ENDPOINT - The endpoint for your S3 storage.
• STORAGE_ACCESS_KEY_ID - The access key for your S3 storage.
• STORAGE_SECRET_ACCESS_KEY - The secret access key for your S3 storage.
• STORAGE_PUBLIC_HOST - The host which is used to access the S3 storage. This is used to generate URLs for the files stored in S3. This will be a subdomain on your locksmith host such as storage.host.com

We use cloudflare r2 for our storage, but any S3 compatible storage should work.

Running tests

Once the database has been configured (per above), make sure to migrate by calling yarn run db:migrate and then call yarn run test:run.

Running Locksmith

For running in production, use yarn start otherwise yarn dev which will restart the server on file changes. This requires using 1password locally and have access to the Unlock Labs vault.

You can start a worker with yarn worker:start.

You can also run scripts with yarn run runner ./src/scripts/script.ts (check the sample file for an example).
