This blog post details the author's experience migrating a JavaScript project from using Prettier and ESLint to BiomeJS. Motivated by a desire to simplify tooling and leverage Biome's integrated linting, formatting, and code analysis, the author outlines the migration process. This involved removing Prettier and ESLint dependencies and configuration, installing Biome, and resolving any initial formatting and linting discrepancies. The post highlights specific configuration adjustments, such as enabling stricter linting rules and configuring editor integration, along with the benefits experienced, including improved performance and a more streamlined development workflow. Ultimately, the author concludes that BiomeJS successfully replaced Prettier and ESLint, offering a more unified and efficient development experience.
This blog post details the author's experience migrating a JavaScript project from using Prettier for code formatting and ESLint for linting to using BiomeJS, a single tool designed to handle both tasks. The author begins by explaining their motivation for the switch, primarily driven by a desire to simplify their development tooling and reduce the complexity and occasional conflicts that can arise from managing two separate tools with overlapping functionality. They highlight the potential for improved performance and a more streamlined developer experience.
The migration process itself is described step-by-step. The author first uninstalled Prettier and ESLint, along with their associated configurations and plugins. Next, they installed BiomeJS and initialized its configuration using the built-in setup wizard. This wizard guided them through selecting the desired formatting and linting rules, helping to create a .biome
configuration file. The author emphasizes the ease of this setup process, particularly the ability to choose from pre-configured rule sets based on popular style guides. They also discuss the ability to customize these rulesets further to match the project's specific requirements.
The blog post then delves into addressing some of the challenges encountered during the migration. One specific challenge was replicating the previous setup’s handling of Markdown files, which required configuring BiomeJS to lint and format Markdown code blocks. This involved specifying the relevant plugins and adjusting settings within the .biome
configuration file. Another challenge arose from differences in the default rules between ESLint and BiomeJS. The author describes how they meticulously compared the previous ESLint configuration with the available BiomeJS rules and adjusted the .biome
file to ensure consistency. This included enabling or disabling specific rules and configuring their options to match the previous behavior as closely as possible.
Furthermore, the author discusses integrating BiomeJS with their editor, Visual Studio Code, for on-the-fly linting and formatting. This integration was achieved through the BiomeJS VS Code extension, which provided real-time feedback and automated code fixes. The post also touches upon integrating BiomeJS into the project's continuous integration/continuous deployment (CI/CD) pipeline to enforce code style and quality checks during the build process.
Finally, the author concludes by summarizing the benefits they experienced after the migration, including a simplified development environment, faster linting and formatting times, and a reduction in configuration complexity. They also express satisfaction with the overall developer experience and encourage other developers to consider adopting BiomeJS for their projects. The author acknowledges that while the migration did require some effort to configure and adjust to the new tool, the overall benefits ultimately justified the switch.

Hacker News users discussed the potential benefits and drawbacks of Biome.js compared to Prettier and ESLint. Some praised Biome.js for its unified approach, simpler configuration, and performance improvements. Others expressed skepticism about switching, citing concerns about the project's relative immaturity, potential lock-in, and the existing robust ecosystem surrounding ESLint and Prettier. The discussion also touched on the fragmentation of JavaScript tooling, with some hoping Biome.js could help consolidate the landscape. A few commenters shared their positive experiences migrating to Biome.js, while others advocated for sticking with the battle-tested combination of Prettier and ESLint. The overall sentiment leaned cautiously optimistic but acknowledged the need for more time to assess Biome.js's long-term viability.
The Hacker News post titled "Migrating a JavaScript Project from Prettier and ESLint to BiomeJS" has generated a moderate discussion with several insightful comments focusing on the practical implications and perceived advantages/disadvantages of switching to Biome.js.
Several commenters express skepticism about the purported benefits of Biome.js, questioning whether the reduced configuration overhead truly outweighs the established ecosystem and familiarity of ESLint and Prettier. One commenter points out the extensive plugin ecosystem of ESLint and Prettier, suggesting that while Biome.js might offer a simpler initial setup, it might lack the flexibility and customization options offered by the more mature tools. This sentiment is echoed by another comment which highlights the wide adoption of ESLint and Prettier, implying that a switch to a less popular tool could potentially increase the learning curve for new developers joining a project.
Another thread of discussion revolves around the performance implications of using Biome.js compared to ESLint and Prettier. One commenter questions whether Biome.js offers any tangible performance improvements, especially considering the ongoing development and optimization of established linters and formatters. This concern reflects a broader skepticism about the necessity of switching to a new tool without clear evidence of significant performance gains.
Some commenters express interest in the integrated approach of Biome.js, appreciating the potential for a more streamlined development workflow. They acknowledge the frustration of managing separate configurations for linting and formatting, suggesting that a unified tool could simplify project setup and maintenance. However, even those expressing interest also voice caution, emphasizing the importance of careful evaluation and community adoption before considering a migration in a production environment.
One commenter specifically highlights the potential for "vendor lock-in" with Biome.js, expressing concern about the risks associated with relying on a relatively new and less established tool. They raise the question of long-term maintenance and support, particularly in the event that the project loses momentum or faces unforeseen challenges.
Finally, some commenters mention alternative tools like Rome and Deno's built-in linting and formatting capabilities, further highlighting the evolving landscape of JavaScript tooling and the ongoing search for optimal development workflows. This suggests that while Biome.js presents an interesting alternative, it enters a competitive field with several established and emerging players.
