Unable to import/use library on clean Angular CLI project

[edoardoo]

Describe the bug
which template:

• MaterialDesignFrameworkModule — Material Design
• Bootstrap3FrameworkModule — Bootstrap 3
• Bootstrap4FrameworkModule — Bootstrap 4
• NoFrameworkModule — plain HTML
• Other (please specify below)

Tried using the library both on the project I'm working on and on a brand new clean project created using Angular CLI. Followed the instructions both on README.md and the example project, both lead to errors.

To Reproduce
Steps to reproduce the behavior:

1. Create new project with Angular CLI: ng new testAngular
2. Install dependencies, modifying package.json and running rm -rf node_modules/ && npm i:

{
  "name": "test-angular",
  "version": "0.0.0",
  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e"
  },
  "private": true,
  "dependencies": {
    "@angular/animations": "~7.0.0",
    "@angular/cdk": "^7.0.0",
    "@angular/common": "~7.0.0",
    "@angular/compiler": "~7.0.0",
    "@angular/core": "~7.0.0",
    "@angular/flex-layout": "^7.0.0-beta.22",
    "@angular/forms": "~7.0.0",
    "@angular/http": "~7.0.0",
    "@angular/material": "^7.2.0",
    "@angular/platform-browser": "~7.0.0",
    "@angular/platform-browser-dynamic": "~7.0.0",
    "@angular/router": "~7.0.0",
    "angular6-json-schema-form": "^7.0.1",
    "core-js": "^2.5.4",

    "@angular/language-service": "~7.0.0",
    "@types/node": "~8.9.4",

    "jasmine-spec-reporter": "~4.2.1",
    "karma": "~3.0.0",
    "karma-chrome-launcher": "~2.2.0",
    "karma-coverage-istanbul-reporter": "~2.0.1",

    "ts-node": "~7.0.0",
    "tslint": "~5.11.0",
    "typescript": "~3.1.6"
  }
}

3. Edit app.module.ts :

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import {
  MatButtonModule,
  MatCardModule,
  MatCheckboxModule,
  MatSidenavModule,
  MatToolbarModule,
  MatIconModule,
  MatListModule,
  MatInputModule,
  MatMenuModule,
  MatDialogModule,
  MatSnackBarModule,
  MatTabsModule,
  MatTableModule,
  MatSortModule,
  MatSelectModule
} from '@angular/material';
import { JsonSchemaFormModule, NoFrameworkModule } from 'angular6-json-schema-form';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    MatButtonModule,
    MatCardModule,
    MatCheckboxModule,
    MatSidenavModule,
    MatToolbarModule,
    MatIconModule,
    MatListModule,
    MatInputModule,
    MatMenuModule,
    MatDialogModule,
    MatSnackBarModule,
    MatTabsModule,
    MatTableModule,
    MatSortModule,
    MatSelectModule,
    NoFrameworkModule,
    NoFrameworkModule, JsonSchemaFormModule.forRoot(NoFrameworkModule)
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

4. Add form tag to html, and scheme data to ts:

<json-schema-form
  loadExternalAssets="true"
  [schema]="yourJsonSchema"
  framework="no-framework"
  (onSubmit)="yourOnSubmitFn($event)">
</json-schema-form>

the yourJsonSchema is a random form taken from the example category
5. ng serve

Expected behavior
The app compile and shows a form.

Screenshots
No relevant screenshot saved.

Desktop (please complete the following information):

• OS: OsX
• Browser Firefox
• Version 65.0b5 (64-bit)

Log output covering before error and any error statements

ERROR in src/app/app.module.ts(23,10): error TS2305: Module '"/Users/edo/Gits/testAngular/node_modules/angular6-json-schema-form/angular6-json-schema-form"' has no exported member 'JsonSchemaFormModule'.

Additional context
Importing the library as specified in the README.md didn't work either.

Hi @edoardoo . That's not how you import angular6-json-schema-form.
You need to follow the following steps as mentioned in the docs
NB: note that you shouldn't import JsonSchemaFormModule :

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { Bootstrap4FrameworkModule } from 'angular6-json-schema-form';

import { AppComponent } from './app.component';

@NgModule({
  declarations: [ AppComponent ],
  imports: [
    BrowserModule
    Bootstrap4FrameworkModule
  ],
  providers: [],
  bootstrap: [ AppComponent ]
})
export class AppModule { }

And you use the component like the following:

<json-schema-form
loadExternalAssets="true"
[schema]="schema"
framework="bootstrap-4"
(onSubmit)="submit($event)">
</json-schema-form>

If you still face the same issue, can you make a repository to reproduce this issue?

This issue may still need to be open. Even if you correctly only import NoFrameworkModule, you get an error saying json-schema-form is not a known element.

If you create a new app, install dependencies, and set up with NoFrameworkModule, this occurs.

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { NoFrameworkModule } from 'angular6-json-schema-form'
import { AppComponent } from './app.component';

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

My current workaround is to also import one of the other modules (e.g. MaterialDesignFrameworkModule).
