Ways of connecting

Connect the main file. In this case, you download the entire database of banks.

<script src="/bower_components/card-info/dist/card-info.min.js"></script>

Connect only the file with the logic, without the database, and the database for your country separately. Bases of banks for each country separately are located in the dist/banks-and-prefixes folder.

<script src="/bower_components/card-info/dist/card-info.core.min.js"></script>
<script src="/bower_components/card-info/dist/banks-and-prefixes/ru.min.js"></script>

Connect as a module in your code

const CardInfo = require('card-info')
// or
import CardInfo from 'card-info'

Cutting Logos

All bank logos in the original size are stored in the folder src/banks-logos. If you installed CardInfo.js in npm, you will be able to use the command npm run build-banks-logos. After its call, all logos from the folder src/banks-logos will be transformed into PNG format, reduced to 600 pixels in width and 200 in height, copied to the folder dist/banks-logos. To change the settings for slicing logos, pass the settings when calling the command like this: npm run build-banks-logos -- -w 1000 -h 300

-w | --width by default 600
Width in pixels to which the image will be reduced/enlarged
-h | --height by default 200
Height in pixels to which the image will be reduced/enlarged
-n | --enlargement is disabled by default If the image is smaller in width or height than the values transferred in the settings, the picture will not be enlarged. However, if you transfer this option, the picture will be forced.
-e | --embed is disabled by default The image decreases/increases in proportion to its original size. So, for example, a picture of 600 × 200, when cutting with the options -w 200 -h 100 becomes 200×50. However, if you pass this option, the picture will become 200×100, and the empty space will be taken by a transparent area.

All the information above also applies to brand logos. The command: npm run build-brands-logos. Source folder: src/brands-logos. The destination folder is dist/brands-logos. The default height is 60 pixels, and the width is not specified.

Performance

The code is checked and works in all browsers, including Internet Explorer 6. To run the tests, run the command npm test or open the file test/browser/main.html in the browser.
