JSON Forms - More Forms. Less Code

Complex forms in the blink of an eye

JSON Forms eliminates the tedious task of writing fully-featured forms by hand by leveraging the capabilities of JSON, JSON Schema and Javascript.

Angular Package

This is the JSON Forms Angular package which provides the necessary bindings for Angular. It uses JSON Forms Core.

You can combine the Angular package with any Angular-based renderer set you want, for example the Material Renderers.

See the official documentation and the JSON Forms Angular seed repository for examples on how to integrate JSON Forms with your application.

Check https://www.npmjs.com/search?q=%40jsonforms for all published JSON Forms packages.


Use the JsonForms component to render a form for your data.

Mandatory props:

  • data: any - the data to show
  • renderers: JsonFormsRendererRegistryEntry[] - the Angular renderer set to use

Optional props:

  • schema: JsonSchema - the data schema for the given data. Will be generated when not given.
  • uischema: UISchemaElement - the UI schema for the given data schema. Will be generated when not given.
  • config: any - form-wide options. May contain default ui schema options.
  • readonly: boolean - whether all controls shall be readonly.
  • uischemas: JsonFormsUiSchemaEntry[] - registry for dynamic ui schema dispatching
  • validationMode: 'ValidateAndShow' | 'ValidateAndHide' | 'NoValidation' - the validation mode for the form
  • ajv: AJV - custom Ajv instance for the form
  • locale - string, for example for formatting numbers
  • dataChange - event emitter which is called on each data change, containing the updated data and the validation result.
  • errors - event emitter which is called with all validations errors.

Example component file app.component.ts:

import { Component } from "@angular/core";
import { angularMaterialRenderers } from "@jsonforms/angular-material";

  selector: "app-root",
  template: `<jsonforms
export class AppComponent {
  renderers = angularMaterialRenderers;
  uischema = {
    type: "VerticalLayout",
    elements: [
        type: "Control",
        label: false,
        scope: "#/properties/done",
        type: "Control",
        scope: "#/properties/name",
        type: "HorizontalLayout",
        elements: [
            type: "Control",
            scope: "#/properties/due_date",
            type: "Control",
            scope: "#/properties/recurrence",
  schema = {
    type: "object",
    properties: {
      name: {
        type: "string",
        minLength: 1,
      done: {
        type: "boolean",
      due_date: {
        type: "string",
        format: "date",
      recurrence: {
        type: "string",
        enum: ["Never", "Daily", "Weekly", "Monthly"],
    required: ["name", "due_date"],
  data = {};

Example module file:

import { NgModule } from "@angular/core";
import { BrowserModule } from "@angular/platform-browser";
import { BrowserAnimationsModule } from "@angular/platform-browser/animations";
import { JsonFormsModule } from "@jsonforms/angular";
import { JsonFormsAngularMaterialModule } from "@jsonforms/angular-material";
import { AppComponent } from "./app.component";

  declarations: [AppComponent],
  imports: [
  schemas: [],
  bootstrap: [AppComponent],

export class AppModule { }
