Using tree-node-cli to Visualize and Manage Project File Structures

When taking over a new project with a complex multi‑layered structure, you may feel unfamiliar or unsure where to start. This article recommends the npm package tree-node-cli , which quickly reveals the overall project structure and displays the hierarchical relationship between files and folders in a concise way.

Background

New projects often contain many files—HTML, CSS, JavaScript, configuration files, etc.—making it hard to locate each file’s purpose and position, especially as the number of files grows.

The tree-node-cli package solves this by generating an impressive tree view that shows the hierarchy of files and directories with a single command.

One‑Click Installation

Install the package globally with a single command:

npm install -g tree-node-cli

Stunning Visual Display

Run the treee command to produce a visually appealing tree of your project files and folders.

Example project structure:

- src
  - js
    - app.js
  - css
    - styles.css
    - theme.css
  - index.html
- public
  - images
    - logo.png
    - banner.png
  - index.html
- README.md

Execute:

treee -L 3 -I "node_modules|.idea|.git" -a --dirs-first

The command produces a clear, indented tree that makes navigation and resource location easy.

Custom Control

The tool offers powerful customization options. By re‑running treee with different parameters you can control depth, exclude patterns, show hidden files, and more.

Key parameters:

-V, --version               Show version number
-a, --all-files             Print all files, including hidden ones
--dirs-first                List directories before files
-d, --dirs-only             List only directories
-s, --sizes                 Show file sizes
-I, --exclude [patterns]    Exclude files matching patterns (e.g., "node_modules|.git")
-L, --max-depth
Maximum display depth
-r, --reverse               Reverse alphabetical order
-F, --trailing-slash        Add '/' to directories
-S, --line-ascii            Use ASCII line drawing
-h, --help                  Show help information

Example to display three levels while excluding common folders and showing hidden files:

treee -L 3 -I "node_modules|.idea|objects|.git" -a --dirs-first

-L 3 : limit depth to three levels.

-I "node_modules|.idea|objects|.git" : ignore specified directories.

-a : include all files, even those starting with a dot.

--dirs-first : list directories before files.

Adapting to File Changes

When files are added or removed, simply re‑run treee to refresh the view. For example, after adding utils.js :

treee -L 3 -I "node_modules|.idea|objects|.git" -a --dirs-first

The updated tree will now include utils.js in the appropriate location.

Differences Between tree, tree-node, and tree-node-cli

While tree and tree-node can display directory structures, tree-node-cli adds interactive command‑line features, higher extensibility, and richer functionality.

tree : basic directory listing, no interactive features.

tree-node : similar to tree , limited to simple node operations, no longer maintained.

tree-node-cli : supports interactive operations, extensive options, and is recommended for modern Node.js environments.

Conclusion

Whether you are a developer, designer, or anyone dealing with complex file structures, the tree-node-cli package can be a valuable assistant, simplifying manual file management, providing clear visualizations, and helping you quickly understand and navigate your project’s layout.
