@jaspero/form-builder

Installation

To install this library, run:

$ npm install --save @jaspero/form-builder

Provide services and values

  1. Provide necessary services
  • StorageService - Used for storing files when FileComponent, ImageComponent or GalleryComponent are used.
  • DbService - Used for fetching referenced relations from your server in runtime
  1. Provide necessary values
  • STORAGE_URL - Root URL for fetching files from your server
  • ROLE - Segments and fields can be conditionally shown/hidden if the value of the role matches what is expected in the schema

Styles

In order to make the generated forms customizable, this library doesn't provide any default styles. This means that the styles need to be loaded in the root of your application. A good starting point are the example styles provided here.

Composing Forms

Definitions

This configuration is used for defining addition field based options. Changing the label or what component is used to represent the field in the form. The Definitions interface looks like this:

Property Type Description Default
label string Label of the field uses the name of the property
hint string Shows a hint below the field if defined -
defaultValue any What the value of the field should be if empty -
component object {type: string, configuration: any} - The type defines the field to use and the configuration is used for any additional component specific options What ever is the default for the property type

Component Types

Name Selector Description Configuration Options
Input input A simple input {type: 'text', 'number', 'email'}

Example

{
  "name": {
    "label": "Name",
    "defaultValue": "John"
  },
  "age": {
    "label": "Age",
    "component": {
      "type": "slider"
    }
  }
}

Adding custom fields

  1. Create a new component that extends FieldComponent. You should inject COMPONENT_DATA in order to receive FieldData, most importantly the underlining FormControl.
  2. Map the newly added component through the CUSTOM_FIELDS provider e.g.
    providers: [{
        provide: CUSTOM_FIELDS
        useValue: {
            'new-component': NewComponent
        }
    }]
  3. You can now use the new field in a forms definitions.

Adding custom components

  1. Create a new component that extends CustomComponent. It receives the CUSTOM_COMPONENT_DATA which has the form and id properties.
  2. Map the newly added component through the CUSTOM_COMPONENTS provider e.g.
    providers: [{
      provide: CUSTOM_COMPONENTS,
      useValue: {
        example: ExampleComponent  
      }
    }] 
  3. You can now use the new component in a segment e.g.
    "segments": [{
      "components": [{"selector": "example"}]
    }]

Handling Array

The form builder supports both arrays of primitives and object arrays.

Object Arrays

The following is required to render an object array:

  1. An object array defined in the schema:
    {
      "addresses": {
       "type": "array",
       "items": {
         "type": "object",
         "properties": {
           "city": {
             "type": "string"
           },
           "address": {
             "type": "string"
           }
         }
       }
      }
    }
  2. A dedicated segment with an array property:
    {
      "segments": [{
        "array": "/addresses",
        "fields": [
          "/city",
          "/address"
        ] 
      }]
    }
  3. You can also optionally define options for each field in the definitions:
    {
      "definitions": {
        "addresses/city": {
          "label": "City"
        }  
      }    
    } 

Primitive Arrays

Primitive arrays can be displayed in two variations as a dedicated segment or as a field.

If the property is defined with out an items value. It's expected to be used as a field. In that case the following components can be used:

  • select in combination with {multiple: true}
  • chips
  • draggable-list

If an items value is defined then it's expected to be rendered as its own segments.

Plugins

Official plugins

TinyMCE WYSIWYG Editor

This plugin registers a field tinymce for rendering the TinyMCE WYSIWYG Editor.

Set up
  1. Install the plugin npm i --save @jaspero/fb-tinymce
  2. Add the plugin module TinymceModule to your module
  3. Install tinymce npm i --save tinymce
  4. Add the following to the assets array in angular.json
    {
        "glob": "**/*",
        "input": "node_modules/tinymce/themes/silver",
        "output": "/themes/silver"
    },
    {
        "glob": "**/*",
        "input": "node_modules/tinymce/skins/ui/oxide",
        "output": "/skins/ui/oxide"
    },
    {
        "glob": "**/*",
        "input": "node_modules/tinymce/skins/content/default",
        "output": "/skins/content/default"
    },
    {
        "glob": "**/*",
        "input": "node_modules/tinymce/plugins",
        "output": "/plugins"
    },
    {
        "glob": "**/*",
        "input": "node_modules/tinymce/icons",
        "output": "/icons"
    }
  5. Add the tinymce script to the scripts array in angular.json "./node_modules/tinymce/tinymce.min.js"
  6. You can optionally add/extend your commonjs dependencies whitelist to get rid of console warnings
        "allowedCommonJsDependencies": [
          "json-pointer",
          "tinymce/plugins/wordcount",
          "tinymce/plugins/table",
          "tinymce/plugins/lists",
          "tinymce/plugins/print",
          "tinymce/plugins/link",
          "tinymce/plugins/image",
          "tinymce/plugins/imagetools",
          "tinymce/plugins/fullscreen",
          "tinymce/plugins/code",
          "tinymce/plugins/autolink",
          "tinymce/plugins/advlist"
        ]

Page Builder

Form UI

Set up
  1. Install the plugin npm i --save @jaspero/fb-page-builder
  2. Add the plugin module PageBuilderModule to your module

Development

Creating a plugin

  1. Run ng g library [plugin-name]
  2. Add @jaspero/ prefix in the projects package.json
  3. Add a release property as well. Example from tincymce plugin.
      "release": {
        "pkgRoot": "../../dist/@jaspero/fb-tinymce",
        "branch": "master",
        "verifyConditions": [
          "@semantic-release/changelog",
          "@semantic-release/npm",
          "@semantic-release/git"
        ],
        "prepare": [
          "@semantic-release/changelog",
          "@semantic-release/npm",
          "@semantic-release/git"
        ],
        "publish": [
          "@semantic-release/npm",
          [
            "@semantic-release/github",
            {
              "assets": [
                "dist/@jaspero/fb-tinymce"
              ]
            }
          ]
        ],
        "plugins": [
          "@semantic-release/commit-analyzer",
          "@semantic-release/release-notes-generator"
        ]
      }
  4. Create ng-package.prod.json example from tinymce
    {
      "$schema": "../../node_modules/ng-packagr/ng-package.schema.json",
      "dest": "../../dist/@jaspero/fb-tinymce",
      "lib": {
        "entryFile": "src/public-api.ts"
      }
    }
  5. In angular.json extend the architect.configurations.production with ng-package.prod.json
     "configurations": {
       "production": {
         "tsConfig": "projects/page-builder/tsconfig.lib.prod.json",
         "project": "projects/page-builder/ng-package.prod.json"
       }
    }
  6. If you need to register fields do it in the plugins module like this:
    export class TinymceModule {
      constructor(
        private ctx: FormBuilderContextService
      ) {
        this.ctx.registerField(
          'tinymce',
          TinymceComponent
        );
      }
    }
  7. Add build scripts for the library in to the root package.json
  8. Build the library and publish an initial version manually. This is required because since it's a scoped package it needs to be explicitly flagged as public. You can do this by running npm publish --access public in dist/@jaspero/[package-name].
