(*): for Mongo connection string options see docs

Run the application with Docker

Create your environment typing :

cp .env.example .env

Then from current project directory run :

docker-compose up

if all right you'll see something like that :

When running with the Docker container you can check data persisted to either Mongo or Redis with their respective web interfaces (Mongo express/Redis Insight). To do so, go to:

• http://localhost:8001 for Redis Insight
• http://localhost:8081 for Mongo Express

Run the application with springboot-plugin

Create your environment:

export $(grep -v '^#' .env.local | xargs)

Then from current project directory run :

mvn validate # --> used to perform ecommerce-commons library checkout from git repo and install throught maven plugin
mvn spring-boot:run

For testing purpose the commons reference can be change from a specific release to a branch by changing the following configurations tags:

FROM:

<scmVersionType>tag</scmVersionType>
<scmVersion>${pagopa-ecommerce-commons.version}</scmVersion>

TO:

<scmVersionType>branch</scmVersionType>
<scmVersion>name-of-a-specific-branch-to-link</scmVersion>

updating also the commons library version to the one of the specific branch

Code formatting

Code formatting checks are automatically performed during build phase. If the code is not well formatted an error is raised blocking the maven build.

Helpful commands:

mvn spotless:check # --> used to perform format checks
mvn spotless:apply # --> used to format all misformatted files

CI

Repo has Github workflow and actions that trigger Azure devops deploy pipeline once a PR is merged on main branch.

In order to properly set version bump parameters for call Azure devops deploy pipelines will be check for the following tags presence during PR analysis:

Tag	Semantic versioning scope	Meaning
patch	Application version	Patch-bump application version into pom.xml and Chart app version
minor	Application version	Minor-bump application version into pom.xml and Chart app version
major	Application version	Major-bump application version into pom.xml and Chart app version
ignore-for-release	Application version	Ignore application version bump
chart-patch	Chart version	Patch-bump Chart version
chart-minor	Chart version	Minor-bump Chart version
chart-major	Chart version	Major-bump Chart version
skip-release	Any	The release will be skipped altogether

For the check to be successfully passed only one of the Application version labels and only ones of the Chart version labels must be contemporary present for a given PR or the skip-release for skipping release step
