backend

StampWallet

Backend serivce for StampWallet app. Requires Go 1.20

Regenerate API models

Make sure that api git submodule is initialised: git submodule init && git submodule update. Or clone with --recurse-submodules

1. Install openapi-generator
2. Run scripts/generateApi.sh from the directory where openapi-generator jar is stored

Build

1. Install Go 1.20
2. make or make bin to just build the binary and skip all tests
3. Run ./stampWalletServer example-config to generate example config

Test

Tests require a working Postgres database with PostGIS extensions. Two environment variables are required to configure the tests:

• TEST_DATABASE_URL - Database URL, for example postgres://postgres@localhost/stampwallet
• TEST_DATABASE_NAME - Test database name, for example stampwallet. NOTE: This database will be dropped and recreated repeatedly. All data from this database WILL be lost.

To set up a Postgres database on docker with PostGIS (example): sudo docker run -e POSTGRES_HOST_AUTH_METHOD=trust -p 5432:5432 -d postgis/postgis

1. go test -v ./... or test . -run "^TestBusiness.*$" to only run tests that match a string

Configuration

example-config subcommand will generate an example configuration file.

BackendDomain: localhost                                        # ?
DatabaseUrl: 'postgresql://user:password@localhost/db'          # Postgres database URL 
EmailVerificationFrontendURL: localhost                         # URL of email verification website
ServerUrl: localhost:8080                                       # IP and port the server will listen on (TODO: change name)
SmtpConfig:
    ServerHostname: smtp.example.com                            # SMTP Server hostname
    ServerPort: 465                                             # SMTP Server port
    Username: test@example.com                                  # SMTP auth username
    Password: 'password'                                        # SMTP auth password
    SenderEmail: test@example.com                               # Email Address to put in "from" field
StoragePath: /tmp/                                              # Where to store uploaded files

Docker image

To build Docker image, run sudo docker buildx build --progress=plain .. Buildkit might be required.

Development docker-compose file is also provided. It will set up both the backend, and the database.

• docker-compose -f docker-compose.yaml build - build image
• docker-compose -f docker-compose.yaml start - start the whole dev stack

To configure the server, copy docker-compose.dev.example.yaml to docker-compose.dev.yaml, change values in docker-compose.dev.yml and add -f docker-compose.dev.yml to next docker-compose runs.

sudo docker-compose -f docker-compose.yaml -f docker-compose.dev.yaml up
