symlink

resolve symlink

realpath

Asynchronously computes the canonical pathname by resolving ., .., and symbolic links.

A canonical pathname is not necessarily unique. Hard links and bind mounts can expose a file system entity through many pathnames.

支持多层 symlink, 但是 symlink 的 target 需要存在, 否则 ENOENT

readlink

读取 link 的字符串信息, 需要 manual resolve

create symlink

术语比较混乱, src, dest, from, target

dir 比较特殊

使用 https://www.npmjs.com/package/symlink-dir

symlink('/dir/a', '/dir/b');
// /dir/b -> /dir/a

签名 symlinkDir(src, dest, opts?), symlink dest 指向 src. (啊!

fs.symlink

import { symlink } from 'node:fs';
symlink('./mew', './mewtwo', callback); 

$ tree .
.
├── mew
└── mewtwo -> ./mew 

ln -s ./mew ./mewtwo

结论

都是 (existing, newSymlinkFile)

$ tree .
.
├── existing
└── newSymlinkFile -> ./existing
