memoize-path文件路径
memoize-path是通过memoized路径段来创建的可重复使用、可堆叠的文件路径。
安装:
$ npm install memoize-path --save
使用(示例):
var memo = require('memoize-path'); /** * When a string is passed, a function is returned */ var cwd = memo(process.cwd()); // use `cwd` var foo = cwd('foo'); var bar = cwd('bar'); var baz = cwd('baz'); // use `foo` var qux = foo('a/b/c'); // use `qux` var fez = qux('x/y/z'); /** * Returns the memoized path when no value is passed */ console.log(cwd()); //=> /User/dev/memo-path console.log(foo()); //=> /User/dev/memo-path/foo console.log(bar()); //=> /User/dev/memo-path/bar console.log(baz()); //=> /User/dev/memo-path/baz console.log(qux()); //=> /User/dev/memo-path/foo/a/b/c console.log(fez()); //=> /User/dev/memo-path/foo/a/b/c/x/y/z /** * The memoized path is also exposed on the function's `.path` property */ console.log(cwd.path); //=> /User/dev/memo-path console.log(foo.path); //=> /User/dev/memo-path/foo console.log(bar.path); //=> /User/dev/memo-path/bar console.log(baz.path); //=> /User/dev/memo-path/baz console.log(qux.path); //=> /User/dev/memo-path/foo/a/b/c console.log(fez.path); //=> /User/dev/memo-path/foo/a/b/c/x/y/z
