## Release Schedule
The project follows a structured release process for each minor version, consisting of three distinct phases:
1. **Development Phase** - 1 week
- Active development of new features
- Code changes merged to the development branch
2. **Feature Freeze** - 1 week
- No new features accepted
- Only bug fixes are cherry-picked to the release branch
- Testing and stabilization of the codebase
3. **Publication**
- Release is published at the end of the freeze period
- Version is finalized and made available to all users
### Nightly Releases
Nightly releases are published daily at [https://github.com/Comfy-Org/ComfyUI_frontend/releases](https://github.com/Comfy-Org/ComfyUI_frontend/releases).
To use the latest nightly release, add the following command line argument to your ComfyUI launch script:
```bat
--front-end-version Comfy-Org/ComfyUI_frontend@latest
```
## Overlapping Release Cycles
The development of successive minor versions overlaps. For example, while version 1.1 is in feature freeze, development for version 1.2 begins simultaneously.
### Example Release Cycle
| Week | Date Range | Version 1.1 | Version 1.2 | Version 1.3 | Patch Releases |
|------|------------|-------------|-------------|-------------|----------------|
| 1 | Mar 1-7 | Development | - | - | - |
| 2 | Mar 8-14 | Feature Freeze | Development | - | 1.1.0 through 1.1.6 (daily) |
| 3 | Mar 15-21 | Released | Feature Freeze | Development | 1.1.7 through 1.1.13 (daily)<br>1.2.0 through 1.2.6 (daily) |
| 4 | Mar 22-28 | - | Released | Feature Freeze | 1.2.7 through 1.2.13 (daily)<br>1.3.0 through 1.3.6 (daily) |
## Release Summary

## Development
### Prerequisites & Technology Stack
- **Required Software**:
- Node.js (v16 or later) and npm
- Git for version control
- A running ComfyUI backend instance
- **Tech Stack**:
- [Vue 3](https://vuejs.org/) with [TypeScript](https://www.typescriptlang.org/)
- [Pinia](https://pinia.vuejs.org/) for state management
- [PrimeVue](https://primevue.org/) with [TailwindCSS](https://tailwindcss.com/) for UI
- [litegraph.js](https://github.com/Comfy-Org/litegraph.js) for node editor
- [zod](https://zod.dev/) for schema validation
- [vue-i18n](https://github.com/intlify/vue-i18n) for internationalization
### Initial Setup
1. Clone the repository:
```bash
git clone https://github.com/Comfy-Org/ComfyUI_frontend.git
cd ComfyUI_frontend
```
2. Install dependencies:
```bash
npm install
```
3. Configure environment (optional):
Create a `.env` file in the project root based on the provided [.env.example](.env.example) file.
**Note about ports**: By default, the dev server expects the ComfyUI backend at `localhost:8188`. If your ComfyUI instance runs on a different port, update this in your `.env` file.
### Dev Server Configuration
To launch ComfyUI and have it connect to your development server:
```bash
python main.py --port 8188
```
### Git pre-commit hooks
Run `npm run prepare` to install Git pre-commit hooks. Currently, the pre-commit
hook is used to auto-format code on commit.
### Dev Server
Note: The dev server will NOT load any extension from the ComfyUI server. Only
core extensions will be loaded.
- Start local ComfyUI backend at `localhost:8188`
- Run `npm run dev` to start the dev server
- Run `npm run dev:electron` to start the dev server with electron API mocked
#### Access dev server on touch devices
Enable remote access to the dev server by setting `VITE_REMOTE_DEV` in `.env` to `true`.
After you start the dev server, you should see following logs:
```
>
[email protected] dev
> vite
VITE v5.4.6 ready in 488 ms
➜ Local: http://localhost:5173/
➜ Network: http://172.21.80.1:5173/
➜ Network: http://192.168.2.20:5173/
➜ press h + enter to show help
```
Make sure your desktop machine and touch device are on the same network. On your touch device,
navigate to `http://<server_ip>:5173` (e.g. `http://192.168.2.20:5173` here), to access the ComfyUI frontend.
### Recommended Code Editor Configuration
This project includes `.vscode/launch.json.default` and `.vscode/settings.json.default` files with recommended launch and workspace settings for editors that use the `.vscode` directory (e.g., VS Code, Cursor, etc.).
We've also included a list of recommended extensions in `.vscode/extensions.json`. Your editor should detect this file and show a human friendly list in the Extensions panel, linking each entry to its marketplace page.
### Recommended MCP Integrations
#### Playwright Browser Automation
The Playwright MCP server enables LLM coding assistants (like Copilot, Claude Code, etc.) to control and inspect web browsers programmatically. This allows assistants to navigate websites, take screenshots, and interact with web pages on your behalf.
For ComfyUI_frontend development, you can ask coding assistants to use Playwright screenshots to continuously verify that your code changes produce the expected visual results.
##### Setup for Claude Code
After installing dependencies with `npm i`, the Playwright MCP server will be automatically available when you start Claude Code locally.
Here's how Claude Code can use the Playwright MCP server to inspect the interface of the local development server (assuming you're running the dev server at `localhost:5173`):
```
> navigate to localhost:5173 and take a screenshot.
tell me the items in the menubar
● I'll navigate to localhost:5173 and take a
screenshot to see the menubar items.

⎿ Read image (94.3KB)
● Based on the screenshot, I can see the menubar at
the top of the ComfyUI interface contains the
following items:
Main Menubar Items:
- Workflow - Menu for workflow-related actions
- Edit - Menu for editing operations
- Help - Menu for help and documentation
Additional UI Elements:
- ComfyUI Logo - On the far left
- Workflow Tab - Shows "Unsaved Workflow" with a
dropdown and close button
- Layout Controls - On the far right (grid view
and hamburger menu icons)
The interface shows a typical ComfyUI workflow
graph with nodes like "Load Checkpoint", "CLIP
Text Encode (Prompt)", "KSampler", and "Empty
Latent Image" connected with colored cables.
```
### Unit Test
- `npm i` to install all dependencies
- `npm run test:unit` to execute all unit tests.
### Component Test
Component test verifies Vue components in `src/components/`.
- `npm run test:component` to execute all component tests.
### Playwright Test
Playwright test verifies the whole app. See <https://github.com/Comfy-Org/ComfyUI_frontend/blob/main/browser_tests/README.md> for details.
### litegraph.js
This repo is using litegraph package hosted on <https://github.com/Comfy-Org/litegraph.js>. Any changes to litegraph should be submitted in that repo instead.
#### Test litegraph.js changes
- Run `npm link` in the local litegraph repo.
- Run `npm link @comfyorg/litegraph` in this repo.
This will replace the litegraph package in this repo with the local litegraph repo.
### i18n
See [locales/README.md](src/locales/README.md) for details.
