Use the appdev Docker images

The appdev Docker images provide a complete WasmEdge application development environment. To use it, do the following.

On x86_64 machines

$ docker pull wasmedge/appdev_x86_64:0.9.0
$ docker run --rm -v $(pwd):/app -it wasmedge/appdev_x86_64:0.9.0
(docker) #

On arm64 machines

$ docker pull wasmedge/appdev_aarch64:0.9.0
$ docker run --rm -v $(pwd):/app -it wasmedge/appdev_aarch64:0.9.0
(docker) #

It installs the following components.

  • WasmEdge CLI and shared libraries
  • WasmEdge with Tensorflow extension CLI and libraries (x86_64 only)
  • Golang
  • Rust
  • Node.js with WasmEdge addons
  • Examples in the /root/examples/ folder

Examples

Hello World. See more simple examples

$ wasmedge hello.wasm world
hello
world

Use AOT to run it much faster.

$ wasmedgec hello.wasm hello.so
$ wasmedge hello.so world
hello
world

Here are some JavaScript examples. See more

$ wasmedge --dir .:. qjs.wasm hello.js 1 2 3
Hello 1 2 3

$ wasmedge-tensorflow-lite --dir .:. qjs_tf.wasm tf_image_classify.js
