# go-wasm-examples

Some small examples of using Go and WebAssembly

The examples require at least **Go version 1.12**!

# Usage

The `server` directory contains a very small HTTP server implementation that 

simply hosts the files of the current working directory.

It also downloads the `wasm_exec.js` JavaScript bridge from the official golang

repository, if the file doesn't already exist.

```bash

go build -o server.bin ./server

./server.bin

```

You can also use any other web-server that provides static file hosting.

## Example 1:

The first example prints a "Hello World" to the console of the browser.

Browse to http://localhost:3000 after building the example:

```bash

GOARCH=wasm GOOS=js go build -o test.wasm ./wasm1

```

## Example 2:

The second example interacts with the DOM of the page and enables the "Stop"

button.

It also registers a click handler on the button and keeps the go program alive 

until the button was pressed.

Browse to http://localhost:3000 after building the example:

```bash

GOARCH=wasm GOOS=js go build -o test.wasm ./wasm2

```

## Example 3:

The third example shows how to create elements in the DOM. It uses the

`github.com/PaulRosset/go-hacknews` package to fetch the top 10 stories from

Hacker News and displays them as list of anchors in the DOM.

Browse to http://localhost:3000 after building the example:

```bash

go get -u github.com/PaulRosset/go-hacknews

GOARCH=wasm GOOS=js go build -o test.wasm ./wasm3

```

## Example 4:

The fourth example implements a very simple markdown editor that uses the

package `github.com/shurcooL/github_flavored_markdown` to render

github-flavoured markdown to HTML.

Browse to http://localhost:3000 after building the example:

```bash

go get -u github.com/shurcooL/github_flavored_markdown

GOARCH=wasm GOOS=js go build -o test.wasm ./wasm4

```
