Potential Memory Leak with Pica Usage in High-Frequency Resizing

[Abhinandan777]

Hi,

Thank you for creating and maintaining this great library!

I’m using Pica to resize images uploaded by users in my application. Currently, I’m creating a new instance of Pica for every uploaded image, as shown below:

img.onload = async () => {
  let picaInstance = pica();
  try {
    const blob = await picaInstance.resize(img, canvas, { quality: 3 });
    // Additional processing...
  } catch (error) {
    console.error(error);
  }
};

Recently, we noticed a memory spike in our application during high-frequency uploads. I suspect it might be related to creating a new Pica instance for each upload.

My questions are:

• Could creating multiple Pica instances cause memory issues or inefficiencies in this scenario?

• Would it be better to move the Pica instance outside the function and reuse it globally?

For context:

• The application handles multiple concurrent uploads.

• Performance and memory optimization are priorities.

I’d appreciate any guidance or recommendations for best practices when using Pica in this way.

Thank you for your help!
