custom.d.ts

/**
 * To use non-code assets with TypeScript, we need to defer the type for these imports.
 * This requires a custom.d.ts file which signifies custom definitions for TypeScript in 
 * our project.

 * Here we declare a new module for SVGs by specifying any import that ends in .svg 
 * and defining the module's content as any. We could be more explicit about it being
 *  a url by defining the type as string. The same concept applies to other assets 
 * including CSS, SCSS, JSON and more.
