Requirements

Currently the only requirement is node.js itself. Server works with either gerrit's API or with direct DB connection. Though DB is default, this behaviour can be controlled with SOURCE_TYPE environment variable.

• nodejs (>= 4.4.1)
• gerrit (>= 2.8, optional, for SOURCE_TYPE=API only)
• gulp (optional, for packaging only)
• docker (optional)
• mysql (optional, for SOURCE_TYPE=DB only)

Configuration

There are some required environment variables you need to define before developing or booting the app.

Environment Variables

• GERRIT_DASHBOARD_CONFIG_PATH: Defines the path for configuration files. (Default: config/)

• NODE_ENV: Defines whether environment is for development or production.

  • development
  • production (default)

• SOURCE_TYPE: Defines which backend will be used for fetching data.

  • API: Requires gerrit.json in GERRIT_DASHBOARD_CONFIG_PATH
  • DB: Requires database_config_<NODE_ENV>.json in GERRIT_DASHBOARD_CONFIG_PATH

Backend Configuration

For gerrit.json you can use the following template:

{
    "host": "gerrit.example.com",
    "username": "gerrit_user",
    "password": "gerrit_pass"
}

For direct database access (regardless of it's development or production) you can use the template below. Using a replicated slave is better here in terms of performance.

{
    "host": "db.example.com",
    "user": "gerrit_db_user",
    "password": "gerrit_db_pwd",
    "database": "gerrit_db_name"
}

Cache Configuration

You can configure caching intervals in config/cache-config.json.

Development

Using CLI:

$ npm install
$ NODE_ENV=development SOURCE_TYPE=DB ./bin/www

Using IDEA:

Select Node.js under Run/Debug Configurations with the options below. Make sure "Include Parent Environment Variables" is turned off under Environment Variables.

Deployment

Docker (Recommended)

A docker file has been created for containerization of this project. By default, it's configured to run in production mode with DB as source type.

/opt/config has been set as GERRIT_DASHBOARD_CONFIG_PATH. This path will be mounted from the host server and should contain necessary configuration files according to above description.

To build the container image:

$ docker build -t gerrit-dashboard-server:1.0.0 .

To tag the image as latest:

$ docker tag gerrit-dashboard-server:1.0.0 gerrit-dashboard-server:latest

To spin a new container from this image:

$ docker run -d \
    --name gerrit-dashboard-server \
    -p 3000:3000 \
    -v $PROJECT_CONFIG_DIR/gerrit-dashboard-server:/opt/config \
    gerrit-dashboard-server

To change environment variable defaults:

$ docker run -d \
    --name gerrit-dashboard-server \
    -p 3000:3000 \
    -e NODE_ENV=development \
    -v $PROJECT_CONFIG_DIR/gerrit-dashboard-server:/opt/config \
    gerrit-dashboard-server

In both of the above commands, change $PROJECT_CONFIG_DIR according to your will.

Endpoints

1. /dashboard

Returns dashboard summary as JSON:

{
    "totalNumberOfProjects": number,
    "numberOfReviews": {
        "open": number,
        "merged": number,
        "abandoned": number,
        "draft": number
    },
    "averageReviewInterval": number
}

2. /stats

Returns detailed statistics as JSON:

{
    "numberOfCommits": number,
    "mostCommitedProjects": {
        "name": string,
        "commits": number
    },
    "topCommitters": {
        "name": string,
        "commits": number
    }
    "topReviewers": {
        "name": string,
        "reviews": number
    }
}

Querying on /stats is possible by making a request to: /stats?filter=TODAY&limit=n

The default value of filter is filter=TODAY. And default value of limit=5.

Filter can be one of these:

• TODAY
• THIS_WEEK
• THIS_MONTH
• LAST_30_DAYS
• LAST_6_MONTHS

3. /version

Returns application version as JSON:

{
    "version": version number,
    "status": boolean
}
