历史
项目历史与用法
flamebearer is a JavaScript CPU trace analysis CLI for Chrome DevTools performance recordings and Node `.cpuprofile` files. The current README positions it as a compact text-summary tool rather than an HTML flame-graph renderer.
项目历史
The official GitHub repository was created in 2018 and was formerly available under Mapbox; GitHub now redirects the Mapbox URL to mourner/flamebearer. The README says version 1 generated an HTML flamegraph for Node traces, then the project lay dormant after 2018.
In 2026 the project was revived with a new purpose: a CLI-oriented analyzer for performance optimization loops, especially useful for agents and humans reading CPU traces without opening a GUI.
采用历史
The package's adoption niche is Node and browser performance work. It can be installed globally with npm, used through `flamebearer-node` to profile a script, or pointed at Chrome trace and Node CPU profile files.
Its README explicitly leaves GUI flamegraph browsing to Speedscope and instead optimizes for one-page terminal summaries, drill-down flags, source-map support, hot source lines, and long-task visibility.
使用方式
Typical commands include `flamebearer-node bench.js`, `flamebearer profile.json.gz`, and `flamebearer CPU.*.cpuprofile`. Drill-down flags restrict stacks, threads, row counts, and time ranges.
The tool does not document a persistent config file or credentials file; usage is command-line and profile-file driven.
为什么软件包爱好者会关心
flamebearer is interesting because it changed identity without abandoning the package: from a Node HTML flamegraph generator inspired by earlier profiling tools into a fast textual trace summarizer aimed at modern command-line workflows.
It sits in the flamegraph family tree but intentionally chooses a terminal-first UX, which makes it attractive for CI logs, scripted profiling runs, and automated performance investigations.
