    I have added Pica.js to my angular 19 application to resize and compress images on the client side. According to the compiler pica is a CommonJS dependency and can cause optimization bailouts.

    As a solution to this i've tried lazy loading pica, only fetching it when it's really necessary. This should help make the intial bundle size of the application smaller. Here's my code:

    private picaInstance: any | null = null;

    async getPica(): Promise<any> {
    if (!this.picaInstance) {
    const PicaModule = await import('pica');
    const Pica = (PicaModule as { default?: any }).default || PicaModule;
    this.picaInstance = Pica();
    }
    return this.picaInstance;
    }


    But despite lazy loading the pica dependency, I still get the following warning on startup:


    image.service.ts depends on 'pica'. CommonJS or AMD dependencies can cause optimization bailouts.
    ​

    How can i use Pica.js without compromising on intial bundle size?
