`#### Options for
dx-scanner run`
Usage: dx-scanner run [path] [options]Scan your project for possible DX recommendations
Options:
-a --authorization credentials to the repository (in format "token" or "username:token"; can be set as ENV variable DXSCANNER_GIT_SERVICE_TOKEN)
-t --apiToken credentials to DX Scanner, can be set as ENV variable DXSCANNER_API_TOKEN
--apiUrl URL of DX Scanner API, can be set as ENV variable DXSCANNER_API_URL (default: https://provider.dxscanner.io/api/v1)
--ci CI mode (default: false)
-d --details print details in reports
--fail exits process with code 1 for any non-practicing condition of given level (high|medium|small|hint|off|all) (default: "off")
--fix tries to fix problems automatically (default: false)
--fixPattern fix only rules with IDs matching the regex
-j --json print report in JSON (default: false)
--html [path] save report in HTML file (default: false, default path: ./report.html)
-r --recursive scan all components recursively in all sub folders (default: false)
--no-recursive disable recursive scan in CI mode
-h, --help output usage information
Examples:
dx-scanner run
dx-scanner run ./ --fail=high
dx-scanner run github.com/DXHeroes/dx-scanner
`
#### Auto-fixer
Fix problems detected by DX Scanner automatically.
`
dx-scanner run [PATH] --fix
`This will try to fix all fixable practices which are not being practices yet.
If you want to omit a practice from automatic fixing, you can do it in the configuration file (see below).
You can also specify
fixPattern flag to fix only a subset of fixable practices.
`
dx-scanner run [PATH] --fix --fixPattern=lint
`Please note, that
fixPattern flag overrides fix settings from configuration file. Therefore practices omitted from fixing by configuration file, but included through fixPattern will be fixed.Configuration ⚙️
Add `dxscannerrc.*` config file to change default configuration settings. It can be a `.json`, `.yml`, or even a dotfile!You can also run
`dx-scanner init` to initialize config automatically.$3
You can switch off practices that you do not want to scan, change their impact level, and even override their default values. To do so, refer to the id of the practice and specify your configuration.

When running DX Scanner with --ci flag, it runs in CI Mode. In CI Mode, DX SCanner uses CIReporter for its output and runs recursively by default (i.e. the --recursive flag is turned on).If you want to disable recursive scan in CI mode, use the
--no-recursive flag.$3
Basic example: run DX Scanner on each push to the repo
Create
.github/workflows/main.yml.`yml
name: DX Scanner
on: push
jobs:
dx-scanner:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v1
- name: Runs DX Scanner on the code
uses: DXHeroes/dx-scanner@master
with:
github_token: ${{ secrets.GITHUB_TOKEN }}
`Generate your Github personal token and set it as an encrypted secret named
GITHUB_TOKEN.Score Computation 💯
The impact of each practice is represented by a specific value. DX Scanner uses these values to calculate the overall DX Score.`
high = 100 pointsmedium = 75 points
small = 50 points
hint = 25 points
``The practices you have switched off are not included in the calculation (0 points).
