Easy to use Angular2 directives for files upload (demo)

Quick start

1. A recommended way to install ng2-file-upload is through npm package manager using the following command:

npm i @familygw/ng2-file-upload --save

Alternatively, you can download it in a ZIP file.

3. More information regarding using of ng2-file-upload is located in demo and demo sources.

Using ng2-file-upload in a project

1. Install as shown in the above section.

2. Import FileUploadModule into the module that declares the component using ng2-file-upload:

import { FileUploadModule } from 'ng2-file-upload';

3. Add it to [imports] under @NgModule:

imports: [ ... FileUploadModule, ... ]

4. Import FileUploader into the component:

import { FileUploader } from 'ng2-file-upload';

5. Create a variable for the API url:

const URL = 'path_to_api';

6. Initialize it:

• fileOver - it fires during 'over' and 'out' events for Drop Area; returns boolean: true if file is over Drop Area, false in case of out. See using in ts demo and html demo
• onFileDrop - it fires after a file has been dropped on a Drop Area; you can pass in $event to get the list of files that were dropped. i.e. (onFileDrop)="dropped($event)"
