Key Points
- Microsoft proposes enhancing the
console.context()method in DevTools to improve contextual logging for web developers. - The proposed changes include adding visual colors to context names, making it easier to filter log messages by context, and standardizing the method across browsers.
- Developers are invited to provide feedback on the proposal to shape the feature’s future implementation.
Microsoft Enhances DevTools with Improved Contextual Logging
Microsoft is addressing a common pain point for web developers working with large codebases: sifting through numerous log messages in the browser console. The company is proposing enhancements to the existing console.context() method in Chromium-based browsers, including Microsoft Edge, to enable more efficient contextual logging.
The Challenge and the Solution
Developers often struggle with identifying the source of log messages in complex applications, making debugging more time-consuming. While console.context() already allows creating separate loggers for different application parts, Microsoft aims to build upon this foundation. The proposed improvements focus on three key areas:
- Standardization: Microsoft wants to standardize the
console.context()method across browsers, ensuring consistency for developers. The company is engaging in discussions on the WHATWG repository to make this a reality. - Visual Recognition: The first enhancement introduces colored context names to make logs more visually distinguishable. Developers can assign a color to a context using a second parameter:
const myColoredLogger = console.context("storage", { color: "lemonchiffon" });This would display a colored badge with the context name in the Console tool, facilitating quick identification. Microsoft is considering alternative approaches, such as using
%cformatting or automatically generating accessible color combinations. - Simplified Filtering: The second improvement streamlines filtering log messages by context. The proposal suggests listing created contexts in the Console tool’s sidebar, allowing developers to click on a context to view only its related logs. This feature would also provide a breakdown of error, warning, info, and debug logs within each context.
Next Steps and Feedback
Microsoft is seeking feedback from the developer community to refine the proposed enhancements. The company encourages developers to review the full proposal, "DevTools contextual logging with console.context()," and share their thoughts by creating a new issue on the MSEdgeExplainers repository.
As the development process progresses, the enhanced console.context() method could significantly improve the debugging experience for web developers working with complex applications in Microsoft Edge and other Chromium-based browsers. The proposed changes aim to make logging more efficient, visually intuitive, and consistent across different browsing environments.
