Check examples directory.
import { Designer } from 'sequential-workflow-designer';
const placeholder = document.getElementById('placeholder');
const definition = {
properties: {
'myProperty': 'my-value',
// global properties...
},
sequence: [
// root steps...
]
};
const configuration = {
theme: 'light', // optional, default: 'light'

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,
globalEditorProvider: (definition, globalContext) => {
const editor = document.createElement('div');
// ...
return editor;
},
stepEditorProvider: (step, stepContext, definition) => {
const editor = document.createElement('div');
// ...
return editor;
}
},
controlBar: true,
contextMenu: true,
};
const designer = Designer.create(placeholder, definition, configuration);
designer.onDefinitionChanged.subscribe((newDefinition) => {
// ...
});You can hide default UI components by setting the corresponding configuration property to false.
