# Invoke UI
Invoke's UI is made possible by many contributors and open-source libraries. Thank you!
## Dev environment
### Setup
1. Install [node] and [pnpm].
1. Run `pnpm i` to install all packages.
#### Run in dev mode
1. From `invokeai/frontend/web/`, run `pnpm dev`.
1. From repo root, run `python scripts/invokeai-web.py`.
1. Point your browser to the dev server address, e.g. <http://localhost:5173/>
### Package scripts
- `dev`: run the frontend in dev mode, enabling hot reloading
- `build`: run all checks (madge, eslint, prettier, tsc) and then build the frontend
- `typegen`: generate types from the OpenAPI schema (see [Type generation])
- `lint:madge`: check frontend for circular dependencies
- `lint:eslint`: check frontend for code quality
- `lint:prettier`: check frontend for code formatting
- `lint:tsc`: check frontend for type issues
- `lint`: run all checks concurrently
- `fix`: run `eslint` and `prettier`, fixing fixable issues
### Type generation
We use [openapi-typescript] to generate types from the app's OpenAPI schema.
The generated types are committed to the repo in [schema.ts].
```sh
# from the repo root, start the server
python scripts/invokeai-web.py
# from invokeai/frontend/web/, run the script
pnpm typegen
```
### Localization
We use [i18next] for localization, but translation to languages other than English happens on our [Weblate] project.
Only the English source strings should be changed on this repo.
### VSCode
#### Example debugger config
```jsonc
{
"version": "0.2.0",
"configurations": [
{
"type": "chrome",
"request": "launch",
"name": "Invoke UI",
"url": "http://localhost:5173",
"webRoot": "${workspaceFolder}/invokeai/frontend/web"
}
]
}
```
#### Remote dev
We've noticed an intermittent timeout issue with the VSCode remote dev port forwarding.
We suggest disabling the editor's port forwarding feature and doing it manually via SSH:
```sh
ssh -L 9090:localhost:9090 -L 5173:localhost:5173 user@host
```
## Contributing Guidelines
Thanks for your interest in contributing to the Invoke Web UI!
Please follow these guidelines when contributing.
### Check in before investing your time
Please check in before you invest your time on anything besides a trivial fix, in case it conflicts with ongoing work or isn't aligned with the vision for the app.
If a feature request or issue doesn't already exist for the thing you want to work on, please create one.
Ping `@psychedelicious` on [discord] in the `#frontend-dev` channel or in the feature request / issue you want to work on - we're happy chat.
### Code conventions
- This is a fairly complex app with a deep component tree. Please use memoization (`useCallback`, `useMemo`, `memo`) with enthusiasm.
- If you need to add some global, ephemeral state, please use [nanostores] if possible.
- Be careful with your redux selectors. If they need to be parameterized, consider creating them inside a `useMemo`.
- Feel free to use `lodash` (via `lodash-es`) to make the intent of your code clear.
- Please add comments describing the "why", not the "how" (unless it is really arcane).
### Commit format
Please use the [conventional commits] spec for the web UI, with a scope of "ui":
- `chore(ui): bump deps`
- `chore(ui): lint`
- `feat(ui): add some cool new feature`
- `fix(ui): fix some bug`
### Submitting a PR
- Ensure your branch is tidy. Use an interactive rebase to clean up the commit history and reword the commit messages if they are not descriptive.
- Run `pnpm lint`. Some issues are auto-fixable with `pnpm fix`.
- Fill out the PR form when creating the PR.
- It doesn't need to be super detailed, but a screenshot or video is nice if you changed something visually.
- If a section isn't relevant, delete it. There are no UI tests at this time.

> This document describes, at a high level, the design and implementation of workflows in the InvokeAI frontend. There are a substantial number of implementation details not included, but which are hopefully clear from the code.
InvokeAI's backend uses graphs, composed of **nodes** and **edges**, to process data and generate images.
