Table of Contents

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

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 or read their documentation:

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"
]

Important!

Before to install the dependency you should have the following script into the polyfills.ts file:

(window as any).global = window;

After that you may encounter compilation issues when using the typings provided by the SDK in an Angular project created using the Angular CLI.

To resolve these issues, either add "types": ["node"] to the project's tsconfig.app.json file, or remove the "types" field entirely.

npm install cap-storage-aws
