React wrapper for the [Sequential Workflow Designer](https://github.com/nocode-js/sequential-workflow-designer) component.

## 🚀 Installation

Install the following packages by [NPM](https://www.npmjs.com/) command:

`npm i sequential-workflow-designer sequential-workflow-designer-react`

Add CSS files to your app:

```tsx
import 'sequential-workflow-designer/css/designer.css';
import 'sequential-workflow-designer/css/designer-light.css';
import 'sequential-workflow-designer/css/designer-dark.css';
```

## 🎬 Usage

Import types:

```tsx
import {
  Definition,
  ToolboxConfiguration,
  StepsConfiguration,
  ValidatorConfiguration
} from 'sequential-workflow-designer';
import {
  SequentialWorkflowDesigner,
  wrapDefinition,
  useGlobalEditor,
  useStepEditor
} from 'sequential-workflow-designer-react';
```

Create or load your definition of a workflow.

```ts
const startDefinition: Definition = { /* ... */ };
```

Wrap the start definition and memorize it.

```tsx
const [definition, setDefinition] = useState(() => wrapDefinition(startDefinition));
```

Configure the designer.

```ts
const toolboxConfiguration: ToolboxConfiguration = { /* ... */ };
const stepsConfiguration: StepsConfiguration = { /* ... */ };
const validatorConfiguration: ValidatorConfiguration = { /* ... */ };
```

Create the global editor component:

```tsx
function GlobalEditor() {
  const { properties, setProperty, definition } = useGlobalEditor();

  function onSpeedChanged(e) {
    setProperty('speed', e.target.value);
  }

  return (
    <>
      <h3>Speed</h3>
      <input value={properties['speed'] || ''} onChange={onSpeedChanged} />
    </>
  );
}
```

Create the step editor component:

```tsx
function StepEditor() {
  const { type, componentType, name, setName, properties, setProperty, definition } = useStepEditor();

  function onNameChanged(e) {
    setName(e.target.value);
  }

  return (
    <>
      <h3>Name</h3>
      <input value={name} onChange={onNameChanged} />
    </>
  );
}
```

At the end attach the designer.

```tsx
<SequentialWorkflowDesigner
  definition={definition}
  onDefinitionChange={setDefinition}
  stepsConfiguration={stepsConfiguration}
  validatorConfiguration={validatorConfiguration}
  toolboxConfiguration={toolboxConfiguration}
  controlBar={true}
  contextMenu={true}
  globalEditor={<GlobalEditor />}
  stepEditor={<StepEditor />}>
  />
```

You can hide any UI component.

```tsx
<SequentialWorkflowDesigner
  // ...
  toolboxConfiguration={false}
  controlBar={false}
  contextMenu={false}
  globalEditor={false}
  stepEditor={false}>
  />
```
