Qodana for JS is based on WebStorm. It provides static analysis for JavaScript or TypeScript projects.

Analyze a project locally

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 field 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 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

Run analysis

Qodana provides two options for local analysis of your code. Qodana CLI is the easiest option to start. Alternatively, you can use the Docker command from the Docker image tab.

Assuming that you have already installed Qodana CLI on your machine, you can run this command in the project root directory:

qodana scan -l jetbrains/qodana-js:2023.1-eap --show-report

To start, pull the image from Docker Hub (only necessary to get the latest version):

docker pull jetbrains/qodana-js:2023.1-eap

Start local analysis with source-directory pointing to the root of your project:

docker run --rm -it \ -v <source-directory>/:/data/project/ \ -p 8080:8080 jetbrains/qodana-js:2023.1-eap --show-report

Open http://localhost:8080 in your browser to examine inspection results. Here, you can also reconfigure the analysis, see the User interface overview section for details. When done, you can stop the web server by pressing Ctrl-C in the console.
