## Grafana v5 Alpha Preview
Grafana master is now v5.0 alpha. This is going to be the biggest and most foundational release Grafana has ever had, coming with a ton of UX improvements, a new dashboard grid engine, dashboard folders, user teams and permissions. Checkout out this [video preview](https://www.youtube.com/watch?v=BC_YRNpqj5k) of Grafana v5.

## Installation
Head to [docs.grafana.org](http://docs.grafana.org/installation/) and [download](https://grafana.com/get)
the latest release.

If you have any problems please read the [troubleshooting guide](http://docs.grafana.org/installation/troubleshooting/).

## Documentation & Support
Be sure to read the [getting started guide](http://docs.grafana.org/guides/gettingstarted/) and the other feature guides.

## Run from master
If you want to build a package yourself, or contribute - Here is a guide for how to do that. You can always find
the latest master builds [here](https://grafana.com/grafana/download)

### Dependencies

- Go 1.9
- NodeJS LTS

### Building the backend
```bash
go get github.com/grafana/grafana
cd ~/go/src/github.com/grafana/grafana
go run build.go setup
go run build.go build
```

### Building frontend assets

For this you need nodejs (v.6+).

```bash
npm install -g yarn
yarn install --pure-lockfile
npm run watch
```

Run tests 
```bash
npm run jest
```

Run karma tests
```bash
npm run karma
```

### Recompile backend on source change

To rebuild on source change.
```bash
go get github.com/Unknwon/bra
bra run
```

Open grafana in your browser (default: `http://localhost:3000`) and login with admin user (default: `user/pass = admin/admin`).

### Dev config

Create a custom.ini in the conf directory to override default configuration options.
You only need to add the options you want to override. Config files are applied in the order of:

1. grafana.ini
1. custom.ini

In your custom.ini uncomment (remove the leading `;`) sign. And set `app_mode = development`.

### Running tests

#### Frontend
Execute all frontend tests
```bash
npm run test
```

Writing & watching frontend tests (we have two test runners)

- jest for all new tests that do not require browser context (React+more)
   - Start watcher: `npm run jest`
   - Jest will run all test files that end with the name ".jest.ts"
- karma + mocha is used for testing angularjs components. We do want to migrate these test to jest over time (if possible).
  - Start watcher: `npm run karma`
  - Karma+Mocha runs all files that end with the name "_specs.ts".

#### Backend
```bash
# Run Golang tests using sqlite3 as database (default)
go test ./pkg/... 

# Run Golang tests using mysql as database - convenient to use /docker/blocks/mysql_tests
GRAFANA_TEST_DB=mysql go test ./pkg/... 

# Run Golang tests using postgres as database - convenient to use /docker/blocks/postgres_tests
GRAFANA_TEST_DB=postgres go test ./pkg/... 
```
