-# angular-library-starter
-[![Build Status](https://travis-ci.org/robisim74/angular-library-starter.svg?branch=master)](https://travis-ci.org/robisim74/angular-library-starter)
->Build an Angular library compatible with AoT compilation &amp; Tree shaking.
+# Development

-This starter allows you to create a library for **Angular 2+** apps written in _TypeScript_, _ES6_ or _ES5_. 
-The project is based on the official _Angular_ packages.
+This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 13.1.3.

-Get the [Changelog](https://github.com/robisim74/angular-library-starter/blob/master/CHANGELOG.md).
+## Development server

-## Contents
-* [1 Project structure](#1)
-* [2 Customizing](#2)
-* [3 Unit testing](#3)
-* [4 Building](#4)
-* [5 Publishing](#5)
-* [6 Documentation](#6)
-* [7 Using the library](#7)
-* [8 What it is important to know](#8)
+Run `ng serve` for a dev server. Navigate to `http://localhost:4200/`. The app will automatically reload if you change any of the source files.

-## <a name="1"></a>1 Project structure
- Library:
-    - **src** folder for the classes
-    - **public_api.ts** entry point for all public APIs of the package
-    - **package.json** _npm_ options
-    - **rollup.config.js** _Rollup_ configuration for building the bundles
-    - **tsconfig-build.json** _ngc_ compiler options for _AoT compilation_
-    - **build.js** building process using _ShellJS_
- Unit testing:
-    - **tests** folder for unit tests
-    - **karma.conf.js** _Karma_ configuration that uses _webpack_ to build the tests
-    - **spec.bundle.js** defines the files used by _webpack_
-    - **tsconfig.json** _TypeScript_ compiler options
- Extra:
-    - **tslint.json** _TypeScript_ linter rules with _Codelyzer_
-    - **travis.yml** _Travis CI_ configuration
+## Code scaffolding

-## <a name="2"></a>2 Customizing
-1. Update [Node & npm](https://docs.npmjs.com/getting-started/installing-node).
+Run `ng generate component component-name` to generate a new component. You can also use `ng generate directive|pipe|service|class|guard|interface|enum|module`.

-2. Rename `angular-library-starter` and `angularLibraryStarter` everywhere to `my-library` and `myLibrary`.
+## Build

-3. Update in `package.json` file:
-    - version: [Semantic Versioning](http://semver.org/)
-    - description
-    - urls
-    - packages
+Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory.

-    and run `npm install`.
+## Running unit tests

-4. Create your classes in `src` folder, and export public classes in `my-library.ts`.
+Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io).

-5. You can create only one _module_ for the whole library: 
-I suggest you create different _modules_ for different functions, 
-so that the user can import only those he needs and optimize _Tree shaking_ of his app.
+## Running end-to-end tests

-6. Update in `rollup.config.js` file `external` & `globals` libraries with those that actually you use.
+Run `ng e2e` to execute the end-to-end tests via a platform of your choice. To use this command, you need to first add a package that implements end-to-end testing capabilities.

-7. Create unit tests in `tests` folder. 
-_Karma_ is configured to use _webpack_ only for `*.ts` files: if you need to test different formats, you have to update it.
+## Further help

-## <a name="3"></a>3 Unit testing
-```Shell
-npm test 
-```
-
-## <a name="4"></a>4 Building
-The following command:
-```Shell
-npm run build
-```
- starts _TSLint_ with _Codelyzer_
- starts _AoT compilation_ using _ngc_ compiler
- creates `dist` folder with all the files of distribution
-
-To test locally the npm package:
-```Shell
-npm run pack-lib
-```
-Then you can install it in an app to test it:
-```Shell
-npm install [path]my-library-[version].tgz
-```
-
-## <a name="5"></a>5 Publishing
-Before publishing the first time:
- you can register your library on [Travis CI](https://travis-ci.org/): you have already configured `.travis.yml` file
- you must have a user on the _npm_ registry: [Publishing npm packages](https://docs.npmjs.com/getting-started/publishing-npm-packages)
-
-```Shell
-npm run publish-lib
-```
-
-## <a name="6"></a>6 Documentation
-To generate the documentation, this starter uses [compodoc](https://github.com/compodoc/compodoc):
-```Shell
-npm run compodoc
-npm run compodoc-serve 
-```
-
-## <a name="7"></a>7 Using the library
-### Installing
-```Shell
-npm install my-library --save 
-```
-### Loading
-#### Using SystemJS configuration
-```JavaScript
-System.config({
-    map: {
-        'my-library': 'node_modules/my-library/bundles/my-library.umd.js'
-    }
-});
-```
-#### Angular-CLI
-No need to set up anything, just import it in your code.
-#### Rollup or webpack
-No need to set up anything, just import it in your code.
-#### Plain JavaScript
-Include the `umd` bundle in your `index.html`:
-```Html
-<script src="node_modules/my-library/bundles/my-library.umd.js"></script>
-```
-and use global `ng.myLibrary` namespace.
-
-### AoT compilation
-The library is compatible with _AoT compilation_.
-
-## <a name="8"></a>8 What it is important to know
-1. `package.json`
-
-    * `"main": "./bundles/angular-library-starter.umd.js"` legacy module format 
-    * `"module": "./bundles/angular-library-starter.es5.js"` flat _ES_ module, for using module bundlers such as _Rollup_ or _webpack_: 
-    [package module](https://github.com/rollup/rollup/wiki/pkg.module)
-    * `"es2015": "./bundles/angular-library-starter.js"` _ES2015_ flat _ESM_ format, experimental _ES2015_ build
-    * `"peerDependencies"` the packages and their versions required by the library when it will be installed
-
-2. `tsconfig-build.json` file used by _ngc_ compiler
-
-    * Compiler options:
-        * `"declaration": true` to emit _TypeScript_ declaration files
-        * `"module": "es2015"` & `"target": "es2015"` are used by _Rollup_ to create the _ES2015_ bundle
-
-    * Angular Compiler Options:
-        * `"skipTemplateCodegen": true,` skips generating _AoT_ files
-        * `"annotateForClosureCompiler": true` for compatibility with _Google Closure compiler_
-        * `"strictMetadataEmit": true` without emitting metadata files, the library will not compatible with _AoT compilation_
-
-3. `rollup.config.js` file used by _Rollup_
-
-    * `format: 'umd'` the _Universal Module Definition_ pattern is used by _Angular_ for its bundles
-    * `moduleName: 'ng.angularLibraryStarter'` defines the global namespace used by _JavaScript_ apps
-    * `external` & `globals` declare the external packages
-
-4. Server-side prerendering
-
-    If you want the library will be compatible with server-side prerendering:
-    * `window`, `document`, `navigator` and other browser types do not exist on the server
-    * don't manipulate the _nativeElement_ directly

 # Angular Infinite Scroll

 versions now follow Angular's version to easily reflect compatibility.  
-Meaning, for **Angular 7**, use `ngx-infinite-scroll @ ^7.0.0`
+Meaning, for **Angular 10**, use `ngx-infinite-scroll @ ^10.0.0`

 ## Angular - Older Versions Support

-For **Angular 6** and **rxjs 6** - `ngx-infinite-scroll@6.0.0`  
+Starting **Angular 6 and Above** - `ngx-infinite-scroll@THE_VERSION.0.0`  
 For **Angular 4** and **Angular = ^5.5.6** - use version `ngx-infinite-scroll@0.8.4`  
 For **Angular 5.x** with **rxjs =<5.5.2** - use version `ngx-infinite-scroll@0.8.3`  
 For Angular version **<= 2.3.1**, you can use `npm i angular2-infinite-scroll` (latest version is 0.3.42) - please notice **the angular2-infinite-scroll** package is deprecated

+# Contribute
+
+## Introduction
+
+First, thank you for considering contributing to ngx-infinite-scroll! It's people like you that make the open source community such a great community! 😊
+
+We welcome any type of contribution, not only code. You can help with 
+- **QA**: file bug reports, the more details you can give the better (e.g. screenshots with the console open)
+- **Marketing**: writing blog posts, howto's, printing stickers, ...
+- **Community**: presenting the project at meetups, organizing a dedicated meetup for the local community, ...
+- **Code**: take a look at the [open issues](issues). Even if you can't write code, commenting on them, showing that you care about a given issue matters. It helps us triage them.
+- **Money**: we welcome financial contributions in full transparency on our [open collective](https://opencollective.com/ngx-infinite-scroll).
+
+## Your First Contribution
+
+Working on your first Pull Request? You can learn how from this *free* series, [How to Contribute to an Open Source Project on GitHub](https://egghead.io/series/how-to-contribute-to-an-open-source-project-on-github).
+
+## Submitting code
+
+Any code change should be submitted as a pull request. The description should explain what the code does and give steps to execute it. The pull request should also contain tests.
+
+## Code review process
+
+The bigger the pull request, the longer it will take to review and merge. Try to break down large pull requests in smaller chunks that are easier to review and merge.
+It is also always helpful to have some context for your pull request. What was the purpose? Why does it matter to you?
+
+## Financial contributions
+
+We also welcome financial contributions in full transparency on our [open collective](https://opencollective.com/ngx-infinite-scroll).
+Anyone can file an expense. If the expense makes sense for the development of the community, it will be "merged" in the ledger of our open collective by the core contributors and the person who filed the expense will be reimbursed.
+
+## Questions
+
+If you have any questions, create an [issue](issue) (protip: do a quick search first to see if someone else didn't ask the same question before!).
+You can also reach us at hello@ngx-infinite-scroll.opencollective.com.

+versions now follow Angular's version to easily reflect compatibility.  
+Meaning, for **Angular 10**, use `ngx-infinite-scroll @ ^10.0.0`
+
+## Angular - Older Versions Support
+
+Starting **Angular 6 and Above** - `ngx-infinite-scroll@THE_VERSION.0.0`  
+For **Angular 4** and **Angular = ^5.5.6** - use version `ngx-infinite-scroll@0.8.4`  
+For **Angular 5.x** with **rxjs =<5.5.2** - use version `ngx-infinite-scroll@0.8.3`  
+For Angular version **<= 2.3.1**, you can use `npm i angular2-infinite-scroll` (latest version is 0.3.42) - please notice **the angular2-infinite-scroll** package is deprecated

+| scrolledUp | EventEmitter | IInfiniteScrollEvent | optional | this will callback if the distance threshold has been reached on a scroll up.   |
+
+## Behavior
+
+By default, the directive listens to the **window scroll** event and invoked the callback.  
+**To trigger the callback when the actual element is scrolled**, these settings should be configured:
+
+- [scrollWindow]="false"
+- set an explict css "height" value to the element
+
+## DEMO
+
+[Try the Demo in StackBlitz](https://stackblitz.com/edit/ngx-infinite-scroll)
+
+## Usage
+
+First, import the InfiniteScrollModule to your module:
+
+```typescript
+import { NgModule } from "@angular/core";
+import { BrowserModule } from "@angular/platform-browser";
+import { InfiniteScrollModule } from "ngx-infinite-scroll";
+import { platformBrowserDynamic } from "@angular/platform-browser-dynamic";
+import { AppComponent } from "./app";
+
+@NgModule({
+  imports: [BrowserModule, InfiniteScrollModule],
+  declarations: [AppComponent],
+  bootstrap: [AppComponent],
+})
+export class AppModule {}
+
+platformBrowserDynamic().bootstrapModule(AppModule);
+```
+
+In this example, the **onScroll** callback will be invoked when the window is scrolled down:
+
+```typescript
+import { Component } from "@angular/core";
+
+@Component({
+  selector: "app",
+  template: `
+    <div
+      class="search-results"
+      infiniteScroll
+      [infiniteScrollDistance]="2"
+      [infiniteScrollThrottle]="50"
+      (scrolled)="onScroll()"
+    ></div>
+  `,
+})
+export class AppComponent {
+  onScroll() {
+    console.log("scrolled!!");
+  }
+}
+```
+
+in this example, whenever the "search-results" is scrolled, the callback will be invoked:
+
+```typescript
+import { Component } from "@angular/core";
+
+@Component({
+  selector: "app",
+  styles: [
+    `
+      .search-results {
+        height: 20rem;
+        overflow: scroll;
+      }
+    `,
+  ],
+  template: `
+    <div
+      class="search-results"
+      infiniteScroll
+      [infiniteScrollDistance]="2"
+      [infiniteScrollThrottle]="50"
+      (scrolled)="onScroll()"
+      [scrollWindow]="false"
+    ></div>
+  `,
+})
+export class AppComponent {
+  onScroll() {
+    console.log("scrolled!!");
+  }
+}
+```
+
+In this example, the **onScrollDown** callback will be invoked when the window is scrolled down and the **onScrollUp** callback will be invoked when the window is scrolled up:
+
+```typescript
+import { Component } from "@angular/core";
+import { InfiniteScroll } from "ngx-infinite-scroll";
+
+@Component({
+  selector: "app",
+  directives: [InfiniteScroll],
+  template: `
+    <div
+      class="search-results"
+      infiniteScroll
+      [infiniteScrollDistance]="2"
+      [infiniteScrollUpDistance]="1.5"
+      [infiniteScrollThrottle]="50"
+      (scrolled)="onScrollDown()"
+      (scrolledUp)="onScrollUp()"
+    ></div>
+  `,
+})
+export class AppComponent {
+  onScrollDown() {
+    console.log("scrolled down!!");
+  }
+
+  onScrollUp() {
+    console.log("scrolled up!!");
+  }
+}
+```
+
+In this example, the **infiniteScrollContainer** attribute is used to point directive to the scrollable container using a css selector. **fromRoot** is used to determine whether the scroll container has to be searched within the whole document (`[fromRoot]="true"`) or just inside the **infiniteScroll** directive (`[fromRoot]="false"`, default option).
+
+```typescript
+import { Component } from "@angular/core";
+
+@Component({
+  selector: "app",
+  styles: [
+    `
+      .main-panel {
+        height: 100px;
+        overflow-y: scroll;
+      }
+    `,
+  ],
+  template: `
+    <div class="main-panel">
+      <div
+        infiniteScroll
+        [infiniteScrollDistance]="2"
+        [infiniteScrollThrottle]="50"
+        [infiniteScrollContainer]="selector"
+        [fromRoot]="true"
+        (scrolled)="onScroll()"
+      ></div>
+    </div>
+  `,
+})
+export class AppComponent {
+  selector: string = ".main-panel";
+
+  onScroll() {
+    console.log("scrolled!!");
+  }
+}
+```
+
+It is also possible to use **infiniteScrollContainer** without additional variable by using single quotes inside double quotes:
+
+```
+[infiniteScrollContainer]="'.main-panel'"
+```

Matt Ezell	c5613d7386	Update postinstall so that it doesn't cause failures (#321 ) There are a few known scenarios where the opencollective postinstall npm script can cause things to break further down the pipeline - a few being 'certain build/CI environments', 'script permission issues' and 'offline installs'.... Arguably, displaying a banner soliciting funding shouldn't disrupt the development or build processes of projects leveraging libraries that are optionally, and non-functionally, using opencollective. Ultimately, at the heart of the failure, is a non 0 exit code being returned in the cases that opencollective fails to properly execute. To prevent this non-zero exit code failure so that subsequent npm processes aren't disrupted as a result of non-functional dependency issues, a "\|\| exit 0" should be added to the postinstall npm script. There are many discussions about this issue and workaround - here are a few: opencollective/opencollective-cli#5 nuxt/nuxt.js#1357 opencollective/opencollective-cli#3 opencollective/opencollective-postinstall#2 `99ea09f6ac`	2019-10-15 10:41:48 -04:00
