CAP STORAGE AWS

CAP STORAGE AWS is a module for Angular, with this module you can upload images to AWS S3.

Previous requirements

CAP STORAGE AWS use bootstrap's classes. To be able to display the component in the right way, bootstrap should have been installed in the project. In case you don't have bootstrap installed, you can run the following command:

npm install bootstrap

One's that you installed bootstrap you have to configure the angular.json and write into styles

"styles": [
  "node_modules/bootstrap/dist/css/bootstrap.min.css",
  "styles.scss"
]

(window as any).global = window;

Implementation into a module

To use this module go-to the app module and into the sections' import and put the AWS module.

After that, add into modules' array with your credentials. Example:

CapStorageAWS.forRoot({
    bucket: 'your-bocket',
    accessKeyId: 'your-accessKeyID',
    secretAccessKey: 'your-secretAccessKey',
    region: 'your-region',
    folder: 'your-folder'
})

Configuration AWS S3

We recommend creating a specific folder into your bucket for save your images. In your bucket go the section of permissions, after that, go to CORS configuration and write the following code:

<?xml version="1.0" encoding="UTF-8"?>
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
<CORSRule>
    <AllowedOrigin>*</AllowedOrigin>
    <AllowedMethod>HEAD</AllowedMethod>
    <AllowedMethod>GET</AllowedMethod>
    <AllowedMethod>POST</AllowedMethod>
    <ExposeHeader>ETag</ExposeHeader>
    <ExposeHeader>x-amz-meta-custom-header</ExposeHeader>
    <AllowedHeader>*</AllowedHeader>
</CORSRule>
</CORSConfiguration>

HTML elements

If you want to upload images, you should use the <photo-upload> tag. This tag provides an HTML that include a button to select your image, a preview section of the image that you want to upload, a progress bar, and a button to upload the image.

Example of implementation

<cap-upload></cap-upload>
