What is ActiveJ?
ActiveJ is an alternative Java platform built from the ground up as a replacement of
Spring,
Spark, Quarkus, Micronauts, and other solutions.
It is minimalistic,
boilerplate-free, and incomparably faster, which is proven by benchmarks.
ActiveJ has minimum third-party dependencies, yet features a full stack of technologies with an efficient async programming model and powerful DI library ActiveInject.
ActiveJ has minimum third-party dependencies, yet features a full stack of technologies with an efficient async programming model and powerful DI library ActiveInject.
ActiveJ consists of several loosely coupled components that complement and empower each
other:
async core (Promise, Eventloop),
efficient I/O processing (CSP,
Datastream), high-performance Jetty and Netty alternatives that can be
used independently of ActiveJ
(HTTP, Net), and handy boot utilities
(Launcher, Service Graph, etc).
Why ActiveJ?
Excellence of your products
Full stack of unique technologies for lightning-fast and asynchronous web
applications with competitive advantage
Superiority of architecture
Lightweight and natively scalable async architecture in contrast to
Spring
and other similar solutions
Ultimate performance
Squeezing the last bits of performance from your hardware, proven by
numerous benchmarks
Simple design
ActiveJ was built from the ground up, so it doesn’t feature tons of
abstractions hiding the legacy standards
A step ahead of other solutions
Minimum web application size
ActiveJ
1.4 MB
Spring

Enjoy the development
Perfectly optimized predefined launchers and classes for both
typical
and more specific use cases combined with ActiveInject DI
library enable extremely fast and convenient app development.
public final class HttpHelloWorldExample extends HttpServerLauncher {
@Provides
AsyncServlet servlet() {
return request -> HttpResponse.ok200().withPlainText("Hello World");
}
public static void main(String[] args) throws Exception {
Launcher launcher = new HttpHelloWorldExample();
launcher.launch(args);
}
}Genuinely high load networking
Ultra-fast means for I/O processing along with a simple abstraction over low-level async sockets I/O. Create servers that process 45M+ RPS on a single CPU core in a few lines of code.
ChannelSupplier.ofSocket(socket)
.transformWith(ChannelDeserializer.create(INT_SERIALIZER))
.transformWith(StreamMapper.create(x -> x + " times 10 = " + x * 10))
.transformWith(ChannelSerializer.create(UTF8_SERIALIZER))
.streamTo(ChannelConsumer.ofSocket(socket));ActiveJ in production
ActiveJ has proved its stability and efficiency in our high-load in-house
projects, processing billions of requests daily. For example, AdKernel
is powered with ActiveJ and it is one of the leading ad-tech solutions providers in the market.
Other ActiveJ technologies
If you want to create something specific or more complex, there is a set of additional ActiveJ
technologies that are perfectly compatible with ActiveJ.
Lightweight Dependency Injection, an extremely
simple and powerful solution.
Significantly outperforms existing solution like Spring DI or Guice.
Extremely fast and space-efficient serializers created with bytecode
engineering. Introduces schema-less approach for the best performance.
Dynamic class and method bytecode generator on top of
ObjectWeb ASM library. Abstracts the complexity of direct
bytecode manipulation and allows to create custom classes on the fly.
Ultra high-performance binary protocol. Allows to build distributed
applications that require efficient client-server interconnections between servers.
Basis for building efficient, scalable remote file storage, supporting
data redundancy, rebalancing,
and resharding.
A little bit of magic to speed up your code. Optimizes code for JVM
and automagically boosts it up by more than 30%.
