Deep dives
Coil: An Android image-loading library
Coil is a lightweight and Kotlin-first image-loading library for Android. It simplifies the process of fetching and decoding images from various sources, providing a simple API for developers. It is built on top of Kotlin and coroutines, making it efficient and easy to use. The library supports features like network request pooling, caching animated images, and placeholder transitions. Coil also offers support for additional media formats like videos and SVGs through modular architecture. The library is widely adopted, with popular apps like Slack, Uber, and Google Play Store leveraging its capabilities. The development of Coil 3.0 is currently underway, with a focus on adding support for Compose multiplatform.
The Origins and Vision of Coil
Colin White, an Android engineer at Cash App, originally started working on Coil to simplify image loading for image-intensive apps like Instacart. He saw an opportunity to create a modern image-loading library that leveraged Kotlin, coroutines, and other Kotlin-first features. Coil's focus is on being lightweight and performant, taking inspiration from libraries like Glide and Picasso while adding its own unique features. Coil is intended to be an open-source library from the beginning, with a strong community response and active feedback contributing to its success.
Future Plans: Multiplatform Support and Beyond
One of the main goals for Coil is to add support for Compose multiplatform in the upcoming version 3.0. Colin is currently working on making Coil compatible with Compose and ensuring a smooth transition for developers. Additionally, Coil aims to introduce features like network request pooling and caching for animated images. The library already provides support for SVGs and video frames, and future plans may include support for MP4s. Despite these expansions, Coil remains committed to maintaining a lightweight and minimalistic approach, offering developers a flexible and efficient image-loading solution.
