JavaScript and TypeScript | Qodana Documentation

Before you start

Install project dependencies

For a basic JavaScript project that has no external dependencies, no preliminary steps are required.

In case the project has external dependencies, you can set them up using the bootstrap key in the qodana.yaml file. For example, if your project dependencies are specified by the yarn.lock file in your project root, add the following line to qodana.yaml:

bootstrap: yarn install

The command will be automatically executed before the analysis. You can use the pnpm, npm or yarn commands to install dependencies.

Enable ESLint

ESLint is widely used in JavaScript projects. You can enable it using the qodana.yaml file:

include:
    - name: Eslint

Qodana Cloud

Because the Qodana for JS linter requires a Qodana Cloud project token for identifying and verifying a license, follow these steps to obtain it:

Navigate to Qodana Cloud and create an account there.
In Qodana Cloud, create an organization, a team, and a project.
On the project card, you can find the project token that you will be using further in this section.

Prepare your software

On the Settings tab of the GitHub UI, create the QODANA_TOKEN encrypted secret and save the project token as its value.
On the Actions tab of the GitHub UI, set up a new workflow and save the following workflow configuration to the .github/workflows/code_quality.yml file:
name: Qodana on: workflow_dispatch: pull_request: push: branches: - main jobs: qodana: runs-on: ubuntu-latest permissions: contents: write pull-requests: write checks: write steps: - uses: actions/checkout@v3 with: ref: ${{ github.event.pull_request.head.sha }} # to check out the actual pull request commit, not the merge commit fetch-depth: 0 # a full history is required for pull request analysis - name: 'Qodana Scan' uses: JetBrains/qodana-action@v2024.2 with: args: --linter,jetbrains/qodana-js:2024.2 env: QODANA_TOKEN: ${{ secrets.QODANA_TOKEN }}
This configuration sample will be modified throughout the section.

In Jenkins, make sure that these plugins are up and running:
- Docker and Docker Pipeline are required for running Docker images,
- Git is required for Git operations in Jenkins projects.
Make sure that Docker is installed and accessible to Jenkins.
If applicable, make sure that Docker is accessible to the jenkins user as described in the Manage Docker as a non-root user section of the Docker documentation.
In Jenkins, create the qodana-token credential and save the project token as its value.
In Jenkins, create a Multibranch Pipeline project as described on the Jenkins documentation portal.

Make sure that your project repository is accessible to GitLab CI/CD.
In GitLab CI/CD, create the $qodana_token variable and save the project token as its value.

In TeamCity, Create a project and a build configuration.

Install Docker on the machine you are going to run Qodana.

If you are using Linux, you should be able to run Docker under your current non-root user.

Follow the instructions from the Qodana CLI page on GitHub.

Run this command to pull the Docker image of the Qodana for JS linter:

docker pull jetbrains/qodana-js:2024.2

Run Qodana

You can run the linters in two modes:

Native mode is the recommended method that lets you run linters without using Docker containers,
Container mode is an alternative that involves Docker containers.

The qodana.yaml file is a universal method of native mode configuration. Alternatively, you can configure it without using the qodana.yaml file.

Save the following configuration in the qodana.yaml file:
ide: QDJS
You can run Qodana using the Qodana Scan GitHub action.
To inspect the main branch, release branches and the pull requests coming to your repository in native mode, save this workflow configuration to the .github/workflows/code_quality.yml file:
name: Qodana on: workflow_dispatch: pull_request: push: branches: # Specify your branches here - main # The 'main' branch - 'releases/*' # The release branches jobs: qodana: runs-on: ubuntu-latest permissions: contents: write pull-requests: write checks: write steps: - uses: actions/checkout@v3 with: ref: ${{ github.event.pull_request.head.sha }} # to check out the actual pull request commit, not the merge commit fetch-depth: 0 # a full history is required for pull request analysis - name: 'Qodana Scan' uses: JetBrains/qodana-action@v2024.2 env: QODANA_TOKEN: ${{ secrets.QODANA_TOKEN }}

You can run Qodana using the Qodana Scan GitHub action.

The `qodana.yaml` file	In the text field, you can set up code analysis used by Qodana in this file. You can learn more about available configuration options
The Send inspection results to Qodana Cloud option	If you want to send reports to Qodana Cloud, you can check this option and paste the project token generated in Qodana Cloud
The Save qodana.yaml in project root option	By checking this option, you can save the Qodana configuration made on this dialog to the `qodana.yaml` file in the project root of your project
The Use Qodana analysis baseline option	Using the baseline feature, you can skip analysis for specific problems

Click Run for analyzing your code.

On the Server-Side Analysis tab of the Problems tool window, see the inspection results.

Explore analysis results

You can load the latest Qodana report from Qodana Cloud to your IDE as explained below.

In your IDE, navigate to Tools | Qodana | Log in to Qodana.
On the Settings dialog, click Log in.
This will redirect you to the authentication page.
Select the Qodana Cloud project to link your local project with.
If you check the Always load most relevant Qodana report option, you will be able to receive the most up-to-date and relevant reports from Qodana Cloud.
In this case, the IDE will search Qodana Cloud and fetch the report with the revision ID corresponding to the current revision ID (HEAD). If this report is not found, the IDE will select the previous report with the revision ID closest to the current revision ID (HEAD). Otherwise, the IDE retrieves the latest available report from Qodana Cloud.
On the Server-Side Analysis tab of the Problems tool window, you can view the analysis results.

After Qodana analyzed your project and uploaded the analysis results to Qodana Cloud, in Qodana Cloud navigate to your project and review the analysis results report.

To learn more about Qodana report UI, see the Inspection report section.

Extend Qodana configuration

Adjusting the scope of analysis

Out of the box, Qodana provides two predefined profiles hosted on GitHub:

qodana.starter is the default profile and a subset of the more comprehensive qodana.recommended profile.
qodana.recommendedis suitable for running in CI/CD pipelines and mostly implements the default WebStorm profile; see the WebStorm documentation for details.

You can customize Qodana profiles using configurations in YAML and XML formats. To learn more about configuration basics, visit the Configure Qodana your way section of the documentation.

Enabling the baseline feature

You can skip analysis for specific problems by using the baseline feature. Information about a baseline is contained in a SARIF-formatted file.

Save the following configuration in the qodana.yaml file:
ide: QDJS
Save the snippet to the .github/workflows/code_quality.yml file containing the args: --baseline,qodana.sarif.json option that specifies the path to the SARIF-formatted baseline file:

- Step ID uniquely identifies this step among other build steps.
- Execute step configures the build condition that will trigger this build step.
- Working directory sets the directory for the build process, see the TeamCity documentation for details. You can leave this field empty if the Checkout directory parameter is specified on the Version Control Settings tab.
- Report ID uniquely identifies the report to let you distinguish between multiple reports when several inspection steps are configured within a single build.
- The Forward reports to TeamCity tests checkbox configures Qodana report availability in the Test tab of the TeamCity UI. Using this option, you can view codebase problems along with other problems detected.
- Linter configures the Qodana linter.
  Here, select the Qodana for JS linter.
- Version is by default set to Latest.
- Inspection profile defines an inspection profile:
  - Recommended (default) is one of the default profiles.
  - Embedded profile lets you select a default profile, see the Existing Qodana profiles section for details.
  - Path to the IntelliJ profile lets you specify the path to your custom profile. To use this option, make sure that you also configure the custom profile in the qodana.yaml file.
- Cloud Token configures a project token generated in Qodana Cloud.
- Additional Docker arguments configures the arguments accepted by a Docker image, see the Shell commands section for details.
- Additional Qodana arguments lets you extend the default Qodana functionality, see the Options section for details.
  In this field, specify the baseline feature using the --baseline <path/to/qodana.sarif.json> option.
Click the Save button.

Choose how you would like to run the baseline feature from the command line:

                            qodana scan \
                                -v <path_to_baseline>:/data/base/ \

                severityThresholds:
                    any: 50 # Total number of problems in all severities
                    critical: 1 # Severities
                    high: 2
                    moderate: 3
                    low: 4
                    info: 5
                testCoverageThresholds:
                    fresh: 6 # Fresh code coverage
