Brief

A developer has successfully replaced ESLint and Prettier with Biome across 16 code repositories, significantly reducing setup complexity and improving performance.

While the migration was largely smooth, the developer noted challenges with Biome's limited plugin ecosystem and a specific import-sorting rule that required manual adjustment. AI
