## 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

})
.then((value: string) => {
// Do something with the value user entered
})
```

```js
// window.confirm
window['app'].extensionManager.dialog
.confirm({
title: 'Test Confirm',
message: 'Test Confirm Message'
})
.then((value: boolean) => {
// Do something with the value user entered
})
```

```js
// window.alert
window['app'].extensionManager.toast
.addAlert("Test Alert")
```

v1.3.34: Register about panel badges
```js
app.registerExtension({

})
// Get the value of a setting
const value = app.ui.settings.getSettingValue('TestSetting')
// Set the value of a setting
app.ui.settings.setSettingValue('TestSetting', 'Hello, universe!')
```
New settings API.
```js
// Register a new setting
app.registerExtension({
name: 'TestExtension1',
settings: [
{

// Set the value of a setting
app.extensionManager.setting.set('TestSetting', 'Hello, universe!')
```
v1.3.7: Register commands and keybindings
Extensions can call the following API to register commands and keybindings. Do
note that keybindings defined in core cannot be overwritten, and some keybindings
are reserved by the browser.
```js
app.registerExtension({
name: 'TestExtension1',
commands: [
{
id: 'TestCommand',
function: () => {
alert('TestCommand')
}
}
],
keybindings: [
{
combo: { key: 'k' },
commandId: 'TestCommand'
}
]
})
```

i
Extensions can call the following API to add toast messages.
```js
app.extensionManager.toast.add({
severity: 'info',
summary: 'Loaded!',
detail: 'Extension loaded!',
life: 3000
})
```
Documentation of all supported options can be found here:

v1.10.9: Selection Toolbox API
Extensions can register commands that appear in the selection toolbox when specific items are selected on the canvas.
```js
app.registerExtension({
name: 'TestExtension1',
commands: [
{
id: 'test.selection.command',
label: 'Test Command',
icon: 'pi pi-star',
function: () => {
// Command logic here
}
}
],
// Return an array of command IDs to show in the selection toolbox
// when an item is selected
getSelectionToolboxCommands: (selectedItem) => ['test.selection.command']
})
```
The selection toolbox will display the command button when items are selected:

## 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:
```
> comfyui-frontend@1.3.42 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://: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.
### 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 for details.
### litegraph.js
This repo is using litegraph package hosted on . 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.
## Troubleshooting
> **Note**: For comprehensive troubleshooting and how-to guides, please refer to our [official documentation](https://docs.comfy.org/). This section covers only the most common issues related to frontend development.
> **Desktop Users**: For issues specific to the desktop application, please refer to the [ComfyUI desktop repository](https://github.com/Comfy-Org/desktop).
### Debugging Custom Node (Extension) Issues
If you're experiencing crashes, errors, or unexpected behavior with ComfyUI, it's often caused by custom nodes (extensions). Follow these steps to identify and resolve the issues:
#### Step 1: Verify if custom nodes are causing the problem
Run ComfyUI with the `--disable-all-custom-nodes` flag:
```bash
python main.py --disable-all-custom-nodes
```
If the issue disappears, a custom node is the culprit. Proceed to the next step.
#### Step 2: Identify the problematic custom node using binary search
Rather than disabling nodes one by one, use this more efficient approach:
1. Temporarily move half of your custom nodes out of the `custom_nodes` directory
```bash
# Create a temporary directory
# Linux/Mac
mkdir ~/custom_nodes_disabled
# Windows
mkdir %USERPROFILE%\custom_nodes_disabled
# Move half of your custom nodes (assuming you have node1 through node8)
# Linux/Mac
mv custom_nodes/node1 custom_nodes/node2 custom_nodes/node3 custom_nodes/node4 ~/custom_nodes_disabled/
# Windows
move custom_nodes\node1 custom_nodes\node2 custom_nodes\node3 custom_nodes\node4 %USERPROFILE%\custom_nodes_disabled\
```
2. Run ComfyUI again
- If the issue persists: The problem is in nodes 5-8 (the remaining half)
- If the issue disappears: The problem is in nodes 1-4 (the moved half)
3. Let's assume the issue disappeared, so the problem is in nodes 1-4. Move half of these for the next test:
```bash
# Move nodes 3-4 back to custom_nodes
# Linux/Mac
mv ~/custom_nodes_disabled/node3 ~/custom_nodes_disabled/node4 custom_nodes/
# Windows
move %USERPROFILE%\custom_nodes_disabled\node3 %USERPROFILE%\custom_nodes_disabled\node4 custom_nodes\
```
4. Run ComfyUI again
- If the issue reappears: The problem is in nodes 3-4
- If issue still gone: The problem is in nodes 1-2
5. Let's assume the issue reappeared, so the problem is in nodes 3-4. Test each one:
```bash
# Move node 3 back to disabled
# Linux/Mac
mv custom_nodes/node3 ~/custom_nodes_disabled/
# Windows
move custom_nodes\node3 %USERPROFILE%\custom_nodes_disabled\
```
6. Run ComfyUI again
- If the issue disappears: node3 is the problem
- If issue persists: node4 is the problem
7. Repeat until you identify the specific problematic node
#### Step 3: Update or replace the problematic node
Once identified:
1. Check for updates to the problematic custom node
2. Consider alternatives with similar functionality
3. Report the issue to the custom node developer with specific details
### Common Issues and Solutions
- **"Module not found" errors**: Usually indicates missing Python dependencies. Check the custom node's `requirements.txt` file for required packages and install them:
```bash
pip install -r custom_nodes/problematic_node/requirements.txt
```
- **Frontend or Templates Package Not Updated**: After updating ComfyUI via Git, ensure you update the frontend dependencies:
```bash
pip install -r requirements.txt
```
- **Can't Find Custom Node**: Make sure to disable node validation in ComfyUI settings.
- **Error Toast About Workflow Failing Validation**: Report the issue to the ComfyUI team. As a temporary workaround, disable workflow validation in settings.
- **Login Issues When Not on Localhost**: Normal login is only available when accessing from localhost. If you're running ComfyUI via LAN, another domain, or headless, you can use our API key feature to authenticate. The API key lets you log in normally through the UI. Generate an API key at [platform.comfy.org/login](https://platform.comfy.org/login) and use it in the API Key field in the login dialog or with the `--api-key` command line argument. Refer to our [API Key Integration Guide](https://docs.comfy.org/essentials/comfyui-server/api-key-integration#integration-of-api-key-to-use-comfyui-api-nodes) for complete setup instructions.
