# Sequential Workflow Designer

[![Build Status](https://img.shields.io/endpoint.svg?url=https%3A%2F%2Factions-badge.atrox.dev%2Fb4rtaz%2Fsequential-workflow-designer%2Fbadge%3Fref%3Dmain&style=flat-square)](https://actions-badge.atrox.dev/b4rtaz/sequential-workflow-designer/goto?ref=main) [![License: MIT](https://img.shields.io/badge/license-MIT-green?style=flat-square)](/LICENSE) [![View this project on NPM](https://img.shields.io/npm/v/sequential-workflow-designer.svg?style=flat-square)](https://npmjs.org/package/sequential-workflow-designer)

Sequential workflow designer with no external dependencies for web applications. It is written in pure TypeScript and uses SVG for rendering. This designer is not associated with any workflow engine, it is fully generic. You can use it to create any kind of application, from graphical programming languages to workflow builders.

Features:

- No external dependencies

- Fully generic and configurable

- Supports light, dark, and soft themes, with easy customization

- Compatible with modern browsers and mobile devices

- Definitions are stored as JSON

- Supports [Angular](./angular/designer/), [React](./react/) and [Svelte](./svelte/).

## 👩‍💻 Integrations

- [⛽ Sequential Workflow Editor](https://github.com/nocode-js/sequential-workflow-editor) - Powerful step editor builder. Don't write step editors manually, build them.

- [🚚 Sequential Workflow Machine](https://github.com/nocode-js/sequential-workflow-machine) - Workflow engine for browser and NodeJS apps, powered by the xstate library.

## 🚀 Installation

To use the designer you should add JS/TS files and CSS files to your project.

### NPM

Install this package by [NPM](https://www.npmjs.com/) command:

`npm i sequential-workflow-designer`

To import the package:

```ts

import { Designer } from 'sequential-workflow-designer';

```

If you use [css-loader](https://webpack.js.org/loaders/css-loader/) or similar, you can add CSS files to your bundle:

```ts

import 'sequential-workflow-designer/css/designer.css';

import 'sequential-workflow-designer/css/designer-light.css';

import 'sequential-workflow-designer/css/designer-soft.css';

import 'sequential-workflow-designer/css/designer-dark.css';

```

To create the designer write the below code:

```ts

// ...

Designer.create(placeholder, definition, configuration);

```

### CDN

Add the below code to your head section in HTML document.

```html

  ...

  

  

  

  

```

Call the designer by:

```js

sequentialWorkflowDesigner.Designer.create(placeholder, definition, configuration);

```

## 🎬 Usage

Check [examples](/examples) directory.

```ts

import { Designer } from 'sequential-workflow-designer';

const placeholder = document.getElementById('placeholder');

const definition = {

  properties: {

    myProperty: 'my-value',

    // root properties...

  },

  sequence: [

    // steps...

  ],

};

const configuration = {

  theme: 'light', // optional, default: 'light'

  isReadonly: false, // optional, default: false

  undoStackSize: 10, // optional, default: 0 - disabled, 1+ - enabled

  steps: {

    // all properties in this section are optional

    iconUrlProvider: (componentType, type) => {

      return `icon-${componentType}-${type}.svg`;

    },

    isDraggable: (step, parentSequence) => {

      return step.name !== 'y';

    },

    isDeletable: (step, parentSequence) => {

      return step.properties['isDeletable'];

    },

    isDuplicable: (step, parentSequence) => {

      return true;

    },

    canInsertStep: (step, targetSequence, targetIndex) => {

      return targetSequence.length < 5;

    },

    canMoveStep: (sourceSequence, step, targetSequence, targetIndex) => {

      return !step.properties['isLocked'];

    },

    canDeleteStep: (step, parentSequence) => {

      return step.name !== 'x';

    },

  },

  validator: {

    // all validators are optional

    step: (step, parentSequence, definition) => {

      return /^[a-z]+$/.test(step.name);

    },

    root: definition => {

      return definition.properties['memory'] > 256;

    },

  },

  toolbox: {

    isCollapsed: false,

    groups: [

      {

        name: 'Files',

        steps: [

          // steps for the toolbox's group

        ],

      },

      {

        name: 'Notification',

        steps: [

          // steps for the toolbox's group

        ],

      },

    ],

  },

  editors: {

    isCollapsed: false,

    rootEditorProvider: (definition, rootContext, isReadonly) => {

      const editor = document.createElement('div');

      // ...

      return editor;

    },

    stepEditorProvider: (step, stepContext, definition, isReadonly) => {

      const editor = document.createElement('div');

      // ...

      return editor;

    },

  },

  controlBar: true,

  contextMenu: true,

};

const designer = Designer.create(placeholder, definition, configuration);

designer.onDefinitionChanged.subscribe(event => {

  // ...

});

```

You can hide default UI components by setting the corresponding configuration property to `false`.

```ts

const configuration = {

  toolbox: false,

  editors: false,

  controlBar: false,

  contextMenu: false,

  // ...

};

```
