# @jaspero/form-builder

## Installation

To install this library, run:

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

### Add Fields and Segments

If you need to render the forms in the UI you'll need to add fields and segments.
Fields and segments are installed separably from the core module.
We provide one set of fields and segments built with material.

```bash
$ npm install --save @jaspero/fb-fields-mat
$ npm install --save @jaspero/fb-segments-mat
```

Add them in to your module like this:

```tsv
@NgModule({
  imports: [
    FbFieldsMatModule.forRoot({prefix: ''}),
    FbSegmentsMatModule.forRoot({prefix: ''}),
  ]
})
```

Giving them an empty `prefix` defines them as the defaults.

### 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
2. 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

```JSON
{
  "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. 
    ```ts
    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.
   ```ts
   providers: [{
     provide: CUSTOM_COMPONENTS,
     useValue: {
       example: ExampleComponent  
     }
   }] 
   ```
3. You can now use the new component in a segment e.g.
    ```json
    "segments": [{
      "components": [{"selector": "example"}]
    }]
    ```

### Handling arrays

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

This plugin doesn't have any additional dependencies.

##### Set up

1. Install the plugin `npm i --save @jaspero/fb-ref-table`
2. Add the plugin module `FbRefTableModule` to your module

__Note:__ If doing something like `users/{{id}}/notifications` it's important to have an initial value for the id.

#### Page Builder

This plugin registers a field `pb-blocks` for rendering a page builder module.

Using `InlineEditorModule` allows for editing blocks inline (not just in the sidebar on the left). There are 3 directives you can utilize.

- `ImageIEDirective(fbPbImageIE)` - This directive is for editing image urls. It adds an edit icon and optionally other custom components.
It strictly needs to be used on a block element that is the direct parent to an image element that has no siblings.
- `SingleLineIEDirective(fbPbSingleLineIE)` - This directive is for editing a single element. It adds a toolbar that allows for element type changes,
alignment and decoration. The directive needs to be placed on the parent element, and the target element should have no siblings.
- `MultiLineIEDirective(fbPbMultiLineIE)` - This directive provides the same functionality as the single line directive but allows for multiline editing.

#### Form UI

This plugin registers a field `fu-fields` for rendering a form builder module.

##### Dependencies

This plugin doesn't have any additional dependencies.

##### Set up

1. Install the plugin `npm i --save @jaspero/fb-form-ui`
2. Add the plugin module `TinymceModule` to your module
3. Add translation files for your specific language. This is en:
    ```json
    {
      "FU": {
        "ID": "ID",
        "LABEL": "Label",
        "VALUE": "Value", 
        "HINT": "Hint",

    {"fields": {"type": "array"}}
    ```
    __layout.segments__
    ```json
    {
      "fields": {
        "component": {
          "type": "fu-fields"
        }
      }
    }
    ```
    __layout.instance.segments__
    ```json
    {
      "type": "empty",
      "fields": ["/fields"]
    }
    ```

    __Conditional Segments__
    ```jsonc
    {
      "fields": [
        "/showTitle",
        {
          "field": "/title", // Field to assign actions
          "deps": ["/showTitle"], // Array of fields on which to listen for a change, if none are provided whole form is used as a listener
          "action": // Single action object or an array of objects
            [
              {
                "type": "show", // "show" | "hide" | "set-to"
                "eval": "(row) => row.showTitle"
              },
              {
                "type": "set-to",
                "eval": "(row) => !row.title",
                "configuration": {

        "output": "./assets/monaco/"
    }
    ```
   

## Development

### Running locally

1. Install dependencies `npm ci`
2. Run the app with `npm start`

### Creating a plugin

1. Run `ng g library [plugin-name] --prefix="fb-[library-prefix]"`
2. Add `@jaspero/` prefix in the projects `package.json`
3. Add a `release` property as well. Example from `tincymce` plugin.
    ```json
      "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
    ```json
    {
      "$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`
    ```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:
    ```typescript
    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`. Make sure to include the build command in the `build:library` script.
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]`.
