Squoosh react-testing-libraryWeb developers, designers, bloggers, and anyone needing to optimize images for the web, particularly those concerned about maintaining image quality while reducing file size.
The only negative thing about this web app, is that it's not clear which formats are supported in which browsers.
Squoosh might be a bit more popular than react-testing-library. We know about 200 links to it since March 2021 and only 137 links to react-testing-library. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
Its a fun challenge. I used https://squoosh.app to make a pretty good one. Mostly just a resize and then OxiPNG for compression. Managed a 124x62 black/white image. OP has a resolution of 195x53, so I had very similar, but slightly worse I think? Mostly a different aspect ratio + map projection I think. Playing with Squoosh.app is very fun, and you can very easily see how the jump from 500b to ~1.5kb turns a map... - Source: Hacker News / 20 days ago
Use a free tool like Squoosh (by Google) to batch convert your existing images to WebP. - Source: dev.to / about 2 months ago
Every image goes through Squoosh before it lands in any repo I own. Drag the file in, pick WebP or AVIF, drag the quality slider until the preview still looks clean, download. The size reduction is usually 60โ80% with no visible quality loss. It runs entirely locally in your browser โ nothing is uploaded anywhere. For a performance-conscious developer this matters. Best for: Pre-commit image optimisation, blog... - Source: dev.to / 3 months ago
The Squoosh image compression app from Google is a great example. It runs codecs like MozJPEG and WebP entirely in WASM, processing large image buffers with minimal boundary crossings. Near-native compression performance, right in the browser. - Source: dev.to / 4 months ago
For images, tools like TinyPNG or Squoosh can reduce file sizes dramatically, often by 60-80%, with little to no visible quality difference. For your splash screen specifically, consider using a simple vector image (SVG) or even a plain color with your logo instead of a heavy raster image. Flutter's native splash screen supports this out of the box and it's blazing fast. - Source: dev.to / 5 months ago
React Testing Libraryโs core philosophy is that we should write our tests in such a way that we simulate user behavior. By testing what the user can actually do, our tests focus less on implementation details and more on the actual user interface, which leads to less brittle tests and a more reliable test suite. - Source: dev.to / 5 months ago
In the main branch, we set up Vitest as the test runner and React Testing Library for rendering the component and simulating user interactions. We also set up MSW to intercept the network requests and return mock responses. - Source: dev.to / 10 months ago
React Testing Library (RTL) provides lightweight utilities built on top of react-dom and react-dom/test-utils, designed to promote testing through user interactions rather than component internals. Instead of working with component instances, RTL encourages querying and asserting against actual DOM nodes, just like real users would. This approach improves test reliability and pushes developers toward writing more... - Source: dev.to / 12 months ago
Testing ensures code reliability and maintainability. Jest, Vitest and React Testing Library are standard tools for unit and integration testing. Unit tests verify individual components, while integration tests ensure features work together. For example, testing a TodoList component might involve:. - Source: dev.to / about 1 year ago
Additionally, I wrote Jest and Enzyme unit tests to demonstrate how to go about unit testing the components, as test driven development (TDD) is another methodology my organization subscribes to. Jest is a unit testing framework that actually shipped with React if you use the Create React App CLI to make a new React project. And at the time, Enzyme was created by Airbnb and added additional functionality to Jest... - Source: dev.to / over 1 year ago
