Usage

Using the project on live environment

The final app hosted on https://base64.pictures.

Using the project on local environment and using it on Stackblitz

Simply go to this URL: https://stackblitz.com/github/ofcyln/image-to-base64

Stackblitz can only show you the visible UI of the project without cloning it to your local environment. Please not that, for security reasons Stackblitz doesn't show images, fonts or font icons that used on the project.

Development server

Run npm start or yarn start for a dev server to initialize. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.

Running scripts

To build the app in Ahead-Of-Time compilation you need to run yarn build:prod or npm run build:prod

To run linter and check the code over tslint rules simply run yarn lint or npm run lint

Code scaffolding

Run ng generate component component-name to generate a new component. If you don't have @angular/cli as a global package on your system, you can run npx ng generate component component-name. You can also use ng generate directive|pipe|service|class|guard|interface|enum|module.

Build

App's Architecture

• Used latest Angular CLI v8.1.2

• Used code scaffolding for effective working and clean development environment. Specialized build, deploy, lint, pre-commit scripts added to package.json.

• lint-staged script cleans and checks the TypeScript, SCSS codes before committing any changes to the repository. prettier, stylelint and tslint plugins run in this script.

• Image to Base64 Converter Project has one major component, 3 shared minor components, one directive and one shared service. Major component is Converter Component - Responsible converting images to Base64 (DataURI), Minor components are Footer Component, Header Component, Not Found Component -wildcard routing redirection component, 404 page-_. Directive is DragDrop Directive and the service is Alert Service.

• Used SCSS as a CSS preprocessor to write efficient CSS codes.

• Used new generation JavaScript (ES6+) with TypeScript.

• Used latest Bootstrap v4.3.1 version to integrate powerful responsive design powered by CSS FlexBox model.

• Used semantic HTML tags and elements with semantic class names.

• Modular components created for reusing components elsewhere to improve modularity in the app.

• Used readonly private properties to prevent magic numbers and strings in the project where it needed into the methods.

• Instead of using images for icons, font icons are integrated into the project with Fontello icon package. Fontello just includes preferred icons, this helps to balance the file size of the icon package.

• The app has multiple icons for various Android, IOS devices.

• Modular components created for reusing components elsewhere to improve modularity in the app.

• PWA integration has been made for the installation of the app to the devices which supports installation.

Motivation of Choices on Implementation

• The upload area is being activated immediately by dragging an image on it. Also, images can be uploaded by upload button as well.

• In case of navigating to a page which doesn't exist in the app, a wildcard route (404) is integrated to the project. It redirects users to the Not Found page.

• If a user doesn't authenticate, page routing redirects users to the Login page to be authenticated. After authorization, with the help of the routerSnapshot queryParams, the user can continue to browsing.

• Mobile device UI behaviours designed to improve User Experience in a performing way and coded with the usage of the @media queries.

• PWA support helps users to install the app on their mobile phone and make them use it as a native app. With the integration of PWA, it is possible to use the app even if there is no connection to the internet. The offline mode makes the app run under unexpected circumstances. PWA integration caches the files with the developer choices. Mostly static files for example image files, icons, font libraries etc.

• Angular production build configuration is used for optimizing bundle, using tree-shaking, aot compilation, compression.

• The total bundle size of the app is ~385KB including all CSS, JS, FONT, ICONS for PWA and HTML files.
