Basic Usage

Import the NgxJsonTableModule in your application module:

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { NgxJsonTableModule } from 'ngx-json-table';
import { AppComponent } from './app.component';

@NgModule({
  declarations: [AppComponent],
  imports: [BrowserModule, NgxJsonTableModule],
  bootstrap: [AppComponent],
})
export class AppModule {}

Use the component in your template:

<!-- Basic usage with default settings -->
<table ngx-json-table [data]="yourJsonData"></table>

<!-- With custom settings -->
<table ngx-json-table [data]="yourJsonData" [settings]="tableSettings"></table>

Define your data and settings in your component:

import { Component } from '@angular/core';
import { Settings, JsonValue } from 'ngx-json-table';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
})
export class AppComponent {
  // Your JSON data
  yourJsonData: JsonValue = {
    product: 'NGX JSON Table',
    version: 1.0,
    features: ['Sorting', 'Editing', 'Nested objects'],
    configuration: {
      sortable: true,
      editable: true,
    },
  };

  // Optional settings
  tableSettings: Settings = {
    sortable: true,
    sortDirection: 'asc',
    expandAll: true,
    loadFromFile: true,
    options: {
      add: true,
      edit: {
        key: true,
        value: true,
      },
      delete: true,
    },
  };
}

Configuration Options

The Settings interface provides various options to customize your table:

export type Settings = {
  // Customize the key column
  key?: {
    headerText?: string; // Default: "Key"
    width?: string; // Default: "40%"
  };

  // Customize the value column
  value?: {
    headerText?: string; // Default: "Value"
    width?: string; // Default: "60%"
  };

  // Enable/disable operations
  options?: {
    add?: boolean; // Enable adding new properties
    edit?: {
      key?: boolean; // Enable editing keys
      value?: boolean; // Enable editing values
    };
    delete?: boolean; // Enable deleting properties
  };

  sortable?: boolean; // Enable sorting
  sortDirection?: 'asc' | 'desc'; // Default sort direction
  expandAll?: boolean; // Expand all nested objects by default
  loadFromFile?: boolean; // Show button to load JSON from file

  // Icon package to use
  iconPackage?: 'basic' | 'font-awesome' | 'material-design';
};

Events

The component provides events to react to data changes:

<table ngx-json-table [data]="data" (dataChange)="onDataChange($event)"></table>

onDataChange(newData: JsonValue) {
  console.log('Data changed:', newData);
  // Update your application state or perform other actions
}

Icon Packages

ngx-json-table supports three icon packages out of the box:

Basic: Default package using HTML entities (no external dependencies)
Font Awesome: Requires Font Awesome to be installed
Material Design: Requires Material Icons to be installed

To use a specific icon package:

tableSettings: Settings = {
  iconPackage: 'material-design',
  // other settings...
};

Here's a complete example with all features enabled:

import { Component } from '@angular/core';
import { Settings, JsonValue } from 'ngx-json-table';

@Component({
  selector: 'app-example',
  template: `
    <table
      ngx-json-table
      [data]="data"
      [settings]="settings"
      (dataChange)="onDataChange($event)"></table>
  `,
})
export class ExampleComponent {
  settings: Settings = {
    key: {
      headerText: 'Property',
      width: '30%',
    },
    value: {
      headerText: 'Data',
      width: '70%',
    },
    sortable: true,
    sortDirection: 'asc',
    expandAll: true,
    loadFromFile: true,
    iconPackage: 'font-awesome',
    options: {
      add: true,
      edit: {
        key: true,
        value: true,
      },
      delete: true,
    },
  };

  data: JsonValue = {
    // Your JSON data here...
  };

  onDataChange(newData: JsonValue) {
    console.log('Data updated:', newData);
    this.data = newData;
  }
}
