Summary:
The `node:` prefix has a few benefits:
- Indicate the import is node builtin module explicitly. No need to look up in node_modules.
- Compatibile with Deno.
To make coding style consistant, migrate existing imports to use `node:` prefix style.
This is done by:
sd "^(import.*')(_http_agent|_http_client|_http_common|_http_incoming|_http_outgoing|_http_server|_stream_duplex|_stream_passthrough|_stream_readable|_stream_transform|_stream_wrap|_stream_writable|_tls_common|_tls_wrap|assert|assert/strict|async_hooks|buffer|child_process|cluster|console|constants|crypto|dgram|diagnostics_channel|dns|dns/promises|domain|events|fs|fs/promises|http|http2|https|inspector|module|net|os|path|path/posix|path/win32|perf_hooks|process|punycode|querystring|readline|repl|stream|stream/consumers|stream/promises|stream/web|string_decoder|sys|timers|timers/promises|tls|trace_events|tty|url|util|util/types|v8|vm|wasi|worker_threads|zlib)(.*)" '${1}node:$2$3' `rg -l import | grep -v node_modules`
Then manually fix import order issues via `yarn eslint --fix`.
The module list is from https://nodejs.org/api/module.html#modulebuiltinmodules
