README

rm-up

Delete files or empty directories and their empty parents from bottom to up.

Synopsis

import rmUp from "rm-up";

await rmUp("generated/template/db/ddl");

await rmUp(["generated/lib/math", "generated/util/helper"], { cwd: "/path/to/project", stop: "." });

Safety

rm-up deletes only files below the options.stop to prevent unintentional delete operations. If the options.stop is not provided rm-up deletes empty directories up to root.

For example:

  • await rmUp("/root/a/b/c", { stop: "root/x" }); // nothing would be deleted.
  • await rmUp("/root/a/b/c", { stop: "root/a" }); // "b" and "c" deleted if empty.

Details

rmUp function deletes files or empty directories and their empty parents from bottom to up. First deletes given files or directories, then checks whether their parent directories are empty and deletes them if empty. Then checks parent's parents and so on.

It's direction is reverse of rm -rf or deltree command.

Ignores system junk files such as .DS_Store and Thumbs.db.

For CLI, please see rm-up-cli.

Why do I need this?

It is most useful when you create a file in a deep path programmatically and want to delete whole created tree, but not sure if other files are added somewhere between by others.

For example you created "generated/template/db/ddl/create.sql" in your project "/path/to/project" and want to delete whole created tree.

Example 1

await rmUp("generated/template/db/ddl/create.sql", { cwd: "/path/to/project" });
project                      project                        project
└─generated/                 └─generated/
  └─template/                  └─template/
    └─db/           --▶          └─db/            --▶
      └─ddl/                       └─ddl/
        └─create.sql                 └─create.sql

create.sql file would be deleted, ddl become empty and deleted, db become empty and deleted, so template and generated directories are deleted likewise.

Example 2

Same options for a little different directory tree:

await rmUp("generated/template/db/ddl/create.sql", { cwd: "/path/to/project" });
project                      project                        project
└─generated/                 └─generated/                   ├─generated/
  ├─assets/                    ├─assets/                    └─assets/
  └─template/        --▶       └─template/        --▶
    └─db/                        └─db/
      └─ddl/                       └─ddl/
        └─create.sql                 └─create.sql

create.sql file would be deleted, ddl become empty and deleted, db become empty and deleted, template become empty and deleted, but this time generated directory not become empty because of assets and not deleted.
