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:
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:
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 tab.
Assuming that you have already installed Qodana CLI on your machine, you can run this command in the project root directory:
Here, the QODANA_TOKEN variable refers to the project token.
To start, pull the image from Docker Hub (only necessary to get the latest version):
Start local analysis with source-directory pointing to the root of your project and QODANA_TOKEN referring to the project token:
In your browser, open Qodana Cloud to examine inspection results. Here, you can also reconfigure the analysis, see the Inspection report section for details.
