TSLint Plugin for Visual Studio Code

TSLint Plugin for Visual Studio Code


Visual Studio Code is a lightweight and extensible code editor that offers a rich ecosystem of extensions to enhance the development experience. Among these extensions, the TSLint plugin is a valuable tool for TypeScript developers.

TSLint: A Brief Introduction

TSLint, an open-source code linter for TypeScript, helps identify and fix potential errors, inconsistencies, and bad practices in TypeScript code. It enforces coding conventions and style rules, improving code quality, consistency, and maintainability.

TSLint Plugin for Visual Studio Code: Unleashing Benefits

The TSLint plugin for Visual Studio Code seamlessly integrates the linter into the code editor, bringing its power directly to the development workflow. By leveraging this plugin, TypeScript developers can:

  • Real-time Code Analysis: Receive immediate feedback on code violations as they write code, enabling prompt identification and correction of potential issues.
  • Visual Indicators: Visualize code violations through colour-coded squiggles and warnings in the editor, facilitating easy identification and navigation to problematic code sections.
  • Integrated Task Runner: Integrate the TSLint task with the Visual Studio Code task runner, ensuring that code adheres to TSLint rules at every stage of the development cycle.
  • Error Prevention: Prevent build failures due to TSLint violations by configuring the task runner to fail when encountering TSLint errors.

Installing and Configuring the TSLint Plugin


To install the TSLint plugin for Visual Studio Code, follow these simple steps:

  1. Open Visual Studio Code.
  2. In the VS Code Extensions pane (Ctrl+Shift+X), search for TSLint and install the extension from the Microsoft extension marketplace.

Configuring the TSLint Plugin

After installing the TSLint plugin, you must configure it to point to your project’s tslint.json file. This file defines the linting rules and configuration. To do this:

  1. Open the Command Palette (Ctrl+Shift+P) and search for TSLint: Configure.
  2. Select the TSLint: Configure by File option.
  3. In the file picker dialog, navigate to your project’s root directory and select the tslint.json file.

Benefits of Integrating TSLint into Visual Studio Code

By integrating the TSLint plugin into Visual Studio Code, TypeScript developers gain several benefits:

  • Improved Code Quality: TSLint continuously monitors code for violations, fostering a culture of high code quality.
  • Early Error Prevention: TSLint detects and reports errors early in the development cycle, preventing them from reaching production.
  • Streamlined Development workflow: TSLint integrates seamlessly into the Visual Studio Code workflow, enabling developers to identify and fix issues promptly.
  • Enhanced Maintainability: Consistent coding practices and adherence to TSLint rules make code easier to maintain and understand for other developers.


The TSLint plugin for Visual Studio Code is an invaluable tool for TypeScript developers, providing real-time code analysis, visual indicators, integrated task running, and error prevention.

By leveraging this plugin, developers can maintain high code quality, prevent bugs, and enhance the overall development experience.
