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 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

Run analysis

tip

You can learn more about running Qodana as root and non-root users from the Configure root and non-root users section.

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 \
   -e QODANA_TOKEN="<cloud-project-token>" \
   -l jetbrains/qodana-js:2024.1

Here, the QODANA_TOKEN variable refers to the project token.
