+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+
+### Building
+
+To install the required dependencies and to build the typescript sources run:
+```
+npm install
+npm run build
+```
+
+### publishing
+
+First build the package then run ```npm publish dist``` (don't forget to specify the `dist` folder!)
+
+### consuming
+
+Navigate to the folder of your consuming project and run one of next commands.
+
+_published:_
+
+```
+npm install @ --save
+```
+
+_without publishing (not recommended):_
+
+```
+npm install PATH_TO_GENERATED_PACKAGE/dist.tgz --save
+```
+
+_It's important to take the tgz file, otherwise you'll get trouble with links on windows_
+
+_using `npm link`:_
+
+In PATH_TO_GENERATED_PACKAGE/dist:
+```
+npm link
+```
+
+In your project:
+```
+npm link 
+```
+
+__Note for Windows users:__ The Angular CLI has troubles to use linked npm packages.
+Please refer to this issue https://github.com/angular/angular-cli/issues/8284 for a solution / workaround.
+Published packages are not effected by this issue.
+
+
+#### General usage
+
+In your Angular project:
+
+
+```
+// without configuring providers
+import { ApiModule } from '';
+import { HttpClientModule } from '@angular/common/http';
+
+@NgModule({
+    imports: [
+        ApiModule,
+        // make sure to import the HttpClientModule in the AppModule only,
+        // see https://github.com/angular/angular/issues/20575
+        HttpClientModule
+    ],
+    declarations: [ AppComponent ],
+    providers: [],
+    bootstrap: [ AppComponent ]
+})
+export class AppModule {}
+```
+
+```
+// configuring providers
+import { ApiModule, Configuration, ConfigurationParameters } from '';
+
+export function apiConfigFactory (): Configuration => {
+  const params: ConfigurationParameters = {
+    // set configuration parameters here.
+  }
+  return new Configuration(params);
+}
+
+@NgModule({
+    imports: [ ApiModule.forRoot(apiConfigFactory) ],
+    declarations: [ AppComponent ],
+    providers: [],
+    bootstrap: [ AppComponent ]
+})
+export class AppModule {}
+```
+
+```
+// configuring providers with an authentication service that manages your access tokens
+import { ApiModule, Configuration } from '';
+
+@NgModule({
+    imports: [ ApiModule ],
+    declarations: [ AppComponent ],
+    providers: [
+      {
+        provide: Configuration,
+        useFactory: (authService: AuthService) => new Configuration(
+          {
+            basePath: environment.apiUrl,
+            accessToken: authService.getAccessToken.bind(authService)
+          }
+        ),
+        deps: [AuthService],
+        multi: false
+      }
+    ],
+    bootstrap: [ AppComponent ]
+})
+export class AppModule {}
+```
+
+```
+import { DefaultApi } from '';
+
+export class AppComponent {
+	 constructor(private apiGateway: DefaultApi) { }
+}
+```
+
+Note: The ApiModule is restricted to being instantiated once app wide.
+This is to ensure that all services are treated as singletons.
+
+#### Using multiple OpenAPI files / APIs / ApiModules
+In order to use multiple `ApiModules` generated from different OpenAPI files,
+you can create an alias name when importing the modules
+in order to avoid naming conflicts:
+```
+import { ApiModule } from 'my-api-path';
+import { ApiModule as OtherApiModule } from 'my-other-api-path';
+import { HttpClientModule } from '@angular/common/http';
+
+@NgModule({
+  imports: [
+    ApiModule,
+    OtherApiModule,
+    // make sure to import the HttpClientModule in the AppModule only,
+    // see https://github.com/angular/angular/issues/20575
+    HttpClientModule
+  ]
+})
+export class AppModule {
+
+}
+```
+
+
+### Set service base path
+If different than the generated base path, during app bootstrap, you can provide the base path to your service. 
+
+```
+import { BASE_PATH } from '';
+
+bootstrap(AppComponent, [
+    { provide: BASE_PATH, useValue: 'https://your-web-service.com' },
+]);
+```
+or
+
+```
+import { BASE_PATH } from '';
+
+@NgModule({
+    imports: [],
+    declarations: [ AppComponent ],
+    providers: [ provide: BASE_PATH, useValue: 'https://your-web-service.com' ],
+    bootstrap: [ AppComponent ]
+})
+export class AppModule {}
+```
+
+
+#### Using @angular/cli
+First extend your `src/environments/*.ts` files by adding the corresponding base path:
+
+```
+export const environment = {
+  production: false,
+  API_BASE_PATH: 'http://127.0.0.1:8080'
+};
+```
+
+In the src/app/app.module.ts:
+```
+import { BASE_PATH } from '';
+import { environment } from '../environments/environment';
+
+@NgModule({
+  declarations: [
+    AppComponent
+  ],
+  imports: [ ],
+  providers: [{ provide: BASE_PATH, useValue: environment.API_BASE_PATH }],
+  bootstrap: [ AppComponent ]
+})
+export class AppModule { }
+```

+# Generated by openapi-generator https://github.com/openapitools/openapi-generator

+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:

+## @openapitools/typescript-angular-petstore@1.0.0
+
+### Building
+
+To install the required dependencies and to build the typescript sources run:
+```
+npm install
+npm run build
+```
+
+### publishing
+
+First build the package then run ```npm publish dist``` (don't forget to specify the `dist` folder!)
+
+### consuming
+
+Navigate to the folder of your consuming project and run one of next commands.
+
+_published:_
+
+```
+npm install @openapitools/typescript-angular-petstore@1.0.0 --save
+```
+
+_without publishing (not recommended):_
+
+```
+npm install PATH_TO_GENERATED_PACKAGE/dist.tgz --save
+```
+
+_It's important to take the tgz file, otherwise you'll get trouble with links on windows_
+
+_using `npm link`:_
+
+In PATH_TO_GENERATED_PACKAGE/dist:
+```
+npm link
+```
+
+In your project:
+```
+npm link @openapitools/typescript-angular-petstore
+```
+
+__Note for Windows users:__ The Angular CLI has troubles to use linked npm packages.
+Please refer to this issue https://github.com/angular/angular-cli/issues/8284 for a solution / workaround.
+Published packages are not effected by this issue.
+
+
+#### General usage
+
+In your Angular project:
+
+
+```
+// without configuring providers
+import { ApiModule } from '@openapitools/typescript-angular-petstore';
+import { HttpClientModule } from '@angular/common/http';
+
+@NgModule({
+    imports: [
+        ApiModule,
+        // make sure to import the HttpClientModule in the AppModule only,
+        // see https://github.com/angular/angular/issues/20575
+        HttpClientModule
+    ],
+    declarations: [ AppComponent ],
+    providers: [],
+    bootstrap: [ AppComponent ]
+})
+export class AppModule {}
+```
+
+```
+// configuring providers
+import { ApiModule, Configuration, ConfigurationParameters } from '@openapitools/typescript-angular-petstore';
+
+export function apiConfigFactory (): Configuration => {
+  const params: ConfigurationParameters = {
+    // set configuration parameters here.
+  }
+  return new Configuration(params);
+}
+
+@NgModule({
+    imports: [ ApiModule.forRoot(apiConfigFactory) ],
+    declarations: [ AppComponent ],
+    providers: [],
+    bootstrap: [ AppComponent ]
+})
+export class AppModule {}
+```
+
+```
+// configuring providers with an authentication service that manages your access tokens
+import { ApiModule, Configuration } from '@openapitools/typescript-angular-petstore';
+
+@NgModule({
+    imports: [ ApiModule ],
+    declarations: [ AppComponent ],
+    providers: [
+      {
+        provide: Configuration,
+        useFactory: (authService: AuthService) => new Configuration(
+          {
+            basePath: environment.apiUrl,
+            accessToken: authService.getAccessToken.bind(authService)
+          }
+        ),
+        deps: [AuthService],
+        multi: false
+      }
+    ],
+    bootstrap: [ AppComponent ]
+})
+export class AppModule {}
+```
+
+```
+import { DefaultApi } from '@openapitools/typescript-angular-petstore';
+
+export class AppComponent {
+	 constructor(private apiGateway: DefaultApi) { }
+}
+```
+
+Note: The ApiModule is restricted to being instantiated once app wide.
+This is to ensure that all services are treated as singletons.
+
+#### Using multiple OpenAPI files / APIs / ApiModules
+In order to use multiple `ApiModules` generated from different OpenAPI files,
+you can create an alias name when importing the modules
+in order to avoid naming conflicts:
+```
+import { ApiModule } from 'my-api-path';
+import { ApiModule as OtherApiModule } from 'my-other-api-path';
+import { HttpClientModule } from '@angular/common/http';
+
+@NgModule({
+  imports: [
+    ApiModule,
+    OtherApiModule,
+    // make sure to import the HttpClientModule in the AppModule only,
+    // see https://github.com/angular/angular/issues/20575
+    HttpClientModule
+  ]
+})
+export class AppModule {
+
+}
+```
+
+
+### Set service base path
+If different than the generated base path, during app bootstrap, you can provide the base path to your service. 
+
+```
+import { BASE_PATH } from '@openapitools/typescript-angular-petstore';
+
+bootstrap(AppComponent, [
+    { provide: BASE_PATH, useValue: 'https://your-web-service.com' },
+]);
+```
+or
+
+```
+import { BASE_PATH } from '@openapitools/typescript-angular-petstore';
+
+@NgModule({
+    imports: [],
+    declarations: [ AppComponent ],
+    providers: [ provide: BASE_PATH, useValue: 'https://your-web-service.com' ],
+    bootstrap: [ AppComponent ]
+})
+export class AppModule {}
+```
+
+
+#### Using @angular/cli
+First extend your `src/environments/*.ts` files by adding the corresponding base path:
+
+```
+export const environment = {
+  production: false,
+  API_BASE_PATH: 'http://127.0.0.1:8080'
+};
+```
+
+In the src/app/app.module.ts:
+```
+import { BASE_PATH } from '@openapitools/typescript-angular-petstore';
+import { environment } from '../environments/environment';
+
+@NgModule({
+  declarations: [
+    AppComponent
+  ],
+  imports: [ ],
+  providers: [{ provide: BASE_PATH, useValue: environment.API_BASE_PATH }],
+  bootstrap: [ AppComponent ]
+})
+export class AppModule { }
+```
