Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Release: WasmEdge 0.12 and 0.12.1
https://github.com/second-state/microservice-rust-mysql
https://github.com/WasmEdge/wasmedge-db-examples
https://github.com/WasmEdge/wasmedge_hyper_demo
WasmEdge is already one of the smallest and most efficient Wasm runtimes out there. It embeds into libsql (SQLite on the server!) to execute user definited functions to perform complex tasks like HTTPS web services & AI inference from SQL statements! https://wasmedge.org/docs/embed/use-case/libsql/
The WasmEdge C++ and Rust SDKs allow host applications to embed Wasm functions asynchronously. It is critically important in many applications where the embedded Wasm function is simply not allowed to block the execution of the host applications. https://github.com/second-state/wasmedge-rustsdk-examples/bl...
Asynchronous host SDKs are complex and a lot of work still remains. We are continuously improving it with our end user and partner communities.

Rust microservices in server-side WebAssembly
The example below, from the microservice-rust-mysql demo app, shows how to create a web server in hyper for WasmEdge. The main listening loop of the web server is as follows:

Release: WasmEdge 0.12 and 0.12.1
https://github.com/WasmEdge/WasmEdge/tree/master/plugins/was...
A good example of WasmEdge 0.12.1 WASI enhancement is the ability to limit the Wasm app to read-only access to files and folders.
WasmEdge sockets API is refactored in 0.12.1 to be compatible with the much more limited WASI socket proposal. WasmEdge sockets have become a super set of WASI sockets.
The WasmEdge networking sockets got new features in version 0.12.1, such as DNS, network device binding and TLS. You will be able to create sophisticated microservices that require highly-efficient non-blocking network sockets. https://github.com/second-state/wasmedge_wasi_socket
Here are several complex networking applications possible with WasmEdge sockets.

Using wasm as a scripting language, is it possible to allow normal, unsandboxed, OS functions?
I tested some simple things with wasmer, and it looks pretty good, the problem is that plugins are completly isolated from the world. This might be exactly what other people are searching, but i want the plugins to be able to open a TcpSocket, read a file, or whatever. I'm aware that i could write my own API for that, like this one.

Running JavaScript in WebAssembly with WasmEdge
First, let’s build a WebAssmbly-based JavaScript interpreter program for WasmEdge. It is based on QuickJS with WasmEdge extensions, such as network sockets and Tensorflow inference, incorporated into the interpreter as JavaScript APIs. You will need to install Rust to build the interpreter.
