![]() Learn more from the TSLint official website. In TSLint configuration file, locate the rule you want to edit and set its ID to warning or to error. Change the severity level of a rule in the TSLint configuration See Code inspections and Change inspection severity for details. For example, errors are highlighted with a red squiggly line, while warnings are marked with a yellow background. These rules will be applied after the rules from tslint.json, tslint.yaml, tslint.yml, or from the above specified custom configuration file and accordingly will override them.īy default, WebStorm marks the detected errors and warnings based on the severity levels from the TSLint configuration file. If necessary, in the Additional Rules Directory field, specify the location of the files with additional code verification rules. Learn more about configuring TSLint from the TSLint official website. ![]() Choose the path from the list, or type it manually, or click and select the relevant file from the dialog that opens. To use a custom file, choose the Configuration File option and specify the location of the file in the Path field. To have WebStorm look for a tslint.json, tslint.yaml, or tslint.yml file, choose the Automatic search option. Accordingly, you have to define the configuration to apply either in a tslint.json, tslint.yaml, or tslint.yml configuration file, or in a custom configuration file, or rely on the default embedded configuration. If no tslint.json, tslint.yaml, or tslint.yml configuration file is found, TSLint uses its default embedded configuration file. WebStorm starts the search from the folder where the file to be checked is stored, then searches in the parent folder, and so on until reaches the project root. In the Configuration File area, appoint the configuration to use.īy default, WebStorm first looks for a tslint.json, tslint.yaml, or tslint.yml configuration file. In the Settings/Preferences dialog ( Ctrl+Alt+S), go to Languages & Frameworks | TypeScript | TSLint. You can also configure TSLint manually to use a custom TSLint package and tslint.json and specify some additional rules. To enable it in a previously created project, go to Languages & Frameworks | TypeScript | TSLint in the Settings/Preferences dialog ( Ctrl+Alt+S) and select the Automatic TSLint configuration option. This behavior is default in all new WebStorm projects. This lets you apply a specific TSLint version or a specific set of plugins to each path in a monorepo or a project with multiple TSLint configurations. If you have several package.json files with TSLint listed as a dependency, WebStorm starts a separate process for each package.json and processes everything below it. If no tslint.json is found in the current file folder, WebStorm will look for one in its parent folders up to the project root.

In the embedded Terminal ( Alt+F12), type: ![]() Make sure the JavaScript and TypeScript and TSLint required plugins are enabled on the Settings/Preferences | Plugins page, tab Installed, see Managing plugins for details. Learn more from Configuring a local Node.js interpreter. The Node Interpreter field shows the default project Node.js interpreter. Make sure a local Node.js interpreter is configured in your project: open the Settings/Preferences dialog ( Ctrl+Alt+S) and go to Languages & Frameworks | Node.js. Make sure you have Node.js on your computer. You can also check your TypeScript code with ESLint, see Lint TypeScript with ESLint. See Configuring TSLint highlighting to learn how to override these settings. By default, WebStorm marks detected problems based on the severity levels from the TSLint configuration file. To view the description of a problem, hover over the highlighted code. When the tool is activated, it lints all the opened TypeScript files and marks the detected problems. You can use the TSLint code verification tool from inside WebStorm and check your TypeScript code for most common mistakes without running the application.
