Claude Code setup slowed by TypeScript compiler cache; 200KB threshold fixes issue

By PulseAugur Editorial · [1 sources] ·

A developer encountered a significant performance issue with their autonomous coding setup, which utilized Claude Code and TypeScript. The problem arose when implementing the `--incremental` flag for the TypeScript compiler to speed up type checking after code edits. While `--incremental` is generally faster for smaller projects, it caused a 3.6x slowdown on a larger project due to the `.tsbuildinfo` cache file becoming excessively large. To resolve this, the developer implemented a threshold guard that reverts to the non-incremental mode if the cache file exceeds 200KB, optimizing performance across different project sizes. AI

    --incremental Made My TypeScript Hook 3.6x Slower. A 200KB Threshold Fixed It

    <p>I started freelancing in college at ¥100k a month, stacked side gigs up to ¥600k, then got laid off and dropped to zero overnight. Over the next six months I built an autonomous Claude Code setup from scratch, and it now runs at ¥1.2M a month in revenue. Of everything that wen…
