Easy to Use
Konva provides an intuitive API for creating 2D canvas applications, making it accessible for developers who may not be familiar with complex graphic programming.
High Performance
It leverages HTML5's Canvas element for rendering, which allows for efficient drawing operations, making it suitable for developing rich, interactive applications.
Rich Manipulation Tools
Konva offers built-in capabilities to easily manipulate and transform shapes, images, and other elements on the canvas, which simplifies the development process.
Layer and Node System
The use of layers and nodes helps in organizing complex scenes efficiently and allows for more advanced features, like hit detection and selective rendering, enhancing performance.
Cross-Platform
Since Konva is HTML5-based, it works on most modern browsers and can run on both desktop and mobile platforms without compatibility issues.
We have collected here some useful links to help you find out if Konva is good.
Check the traffic stats of Konva on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
Check the "Domain Rating" of Konva on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of Konva's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
Check the "Domain Authority" of Konva on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.

Enter Konva.js — a 2D canvas framework that makes rendering, transforming, and exporting graphics simple. - Source: dev.to / 8 months ago
I have been assigned a task to create a sort of a canva clone which will have almost same features as canva with authentication, access control and rating system(not in this phase). I need help in finding libraries similar to https://konvajs.org/ which has updated docs and great support for Nextjs. Source: over 2 years ago

All the UI part would make sense to do in React. The actual drawing board you likely would need to implement in canvas or SVG. It still could be a React component, but for actual drawing, you'd probably use something like Konva (https://konvajs.org/). Source: over 3 years ago
During the development of a complex interactive UI for the configuration of a digital laboratory ecosystem, we were utilizing the Konva.js library. Konva is a wrapper around the HTML canvas that simplifies working with shapes and interacting with the canvas a lot. Everybody dealing with the plain canvas API knows how much code certain tasks require, especially when user interaction with the drawn shapes is... - Source: dev.to / over 3 years ago

For clarity - inside the Canvas component, I have a Stage component, inside that there's a Layer component, inside that there's an Items component (I'm using Konva and need to have all this nesting). Source: about 4 years ago
Because I have huge experience with maintaining open source. Open source is cool. But monetization of open-source work is very unsustainable these days. I am a maintainer of https://konvajs.org/. It is the most popular JS library for canvas drawing. I spend time on it every day: support, documentation, answering questions, etc. Do you know how much I have from donations? 400 USD per month is max I had. Large... Source: about 4 years ago
I'm building an app for work for a client to draw stuff on map images (very technical ones for train drivers, not Google Maps). I'm using React and Konva. Source: about 4 years ago
Both Fabric.js and Konva should be able to help you with this requirement, if you're happy with a canvas-based solution. If you prefer SVG then you could use something like SVG.js. Source: over 4 years ago
Either you use a frontend framework or vanilla JS/TS take a look at one of these wonderful libraries. Our choice is awesome Konva.js with react-konva bindings. It abstracts away low-level details, like redrawing, bubbling or layering inside canvas. Konva supports many useful shapes like Rect, Circle, Text, Arrow, that you can use out of the box to construct UI. So instead of imperative low-level code:. - Source: dev.to / almost 5 years ago

The three Javascript libraries that might be most useful for this task are: Konva.js, Fabric.js and Two.js. I believe they all have functionality to create a canvas representation from (fairly complex) SVG. And all of them are being actively maintained with communities (well, maintainers) willing to answer questions should you get stuck. Source: almost 5 years ago
Let's move to the canvas. Here, the main job is done by Konva, which provides us with a simple and performant layer on top of the raw HTML canvas element. Shelly uses a rather basic subset of Konva, as Shelly's drawings are composed mainly of lines, arches, basic figures, and SVG patterns (hearts, stars, cars, etc.). One aspect that was especially challenging, however, was properly handling the zoom & pan, using... - Source: dev.to / about 5 years ago
Konva.js is a versatile JavaScript library that provides a convenient abstraction over HTML5 canvas, easing the development of dynamic graphics, animations, and 2D game interfaces in web applications. It is frequently used in projects that require interactive user interfaces with complex shapes, which otherwise would necessitate extensive code if directly tackling the HTML canvas API. This has garnered it favorable opinions in the technical community, particularly for simplifying the intricacies associated with canvas drawings.
Public sentiment about Konva suggests that while it is not the most popular tool in its niche, it is appreciated for its robust feature set and active maintenance by its open-source community. Notably, Konva competes with other canvas and UI libraries such as Fabric.js, GoJS, and PixiJS, among others. Though Fabric.js is recognized to be slightly more popular and active, Konva's commitment to continuous improvement and support is acknowledged by developers who rely on it.
Users implementing Konva in their projects highlight the ease of integrating it with React, as facilitated by the react-konva bindings. This integration abstracts low-level details such as redrawing and event bubbling, enabling developers to focus on higher-level functionalities. Some developers appreciate Konva's simplicity when constructing UI elements through built-in shape components like Rect, Circle, and Arrow.
Konva is particularly praised for its event management capabilities and its proficiency in handling complex user interactions. This is exemplified in its use in various innovative projects, such as creating online design editors, building custom map-drawing tools, and constructing graphic editors for e-commerce platforms.
Despite these positive reviews, the financial compensation for maintaining Konva is limited, as highlighted by one of its maintainers. This reflects a broader challenge faced by open-source projects where the revenue does not equate to the value provided to large companies using the library. Nonetheless, the community's backing of Konva through contributions and collaboration opportunities with companies demonstrates support for ongoing development and enhancement.
Furthermore, Konva's ability to be integrated into different types of projects—whether using frameworks like Angular or React or even in vanilla JavaScript applications—showcases its flexibility and broad appeal. Developers recognize its suitability for applications requiring high-performance custom graphics, like video editing tools and interactive web applications.
Overall, Konva holds a strong place among JavaScript libraries for creating drawing applications, providing extensive functionality wrapped in an easy-to-use interface. Its continuous evolution and user satisfaction are testaments to its efficacy in simplifying HTML5 canvas operations.
