README
⚠️ Joy development is currently **on hold**. Recent Go -> WASM developments look like a more promising path to Go being a great choice for frontend development. I'm thrilled to see development moving so quickly now and I think our efforts are better spent improving the Go to WASM compiler. As for Joy, there are quite a few interesting nuggets of code in here that I'd encourage you to dig up, polish and open source 😊
Thanks for your interest in this project!
❤️ **Matt**

## Getting Started
**1. Install Joy:**
```sh
curl -sfL https://raw.githubusercontent.com/matthewmueller/joy/master/install.sh | sh
```
> Note: you can also download from the [releases tab](https://github.com/matthewmueller/joy/releases).
**2. Create a `main.go` file with the following code:**
```go
package main
func main() {
println("hi world!")
}
```
**3. Run the code in a real browser:**
```sh
joy run main.go
```
**4. See the compiled Javascript:**
```sh
joy main.go
```
## Examples
Visit https://mat.tm/joy/#examples or peruse the [test suite](https://github.com/matthewmueller/joy/tree/master/testdata).
## Using the CLI
**Compile Go into Javascript:**
```
joy
```
**Compile and run the Go code in headless chrome:**
```
joy run
```
**Build a development version of the code:**
```
joy build --dev ...
```
**Build a production version of the code (coming soon!):**
```
joy build ...
```
**Start a development server with livereload:**
```
joy serve ...
```
> Run `joy help` for additional details.
## Contributing
So happy to hear you're interested in contributing! Here's a quick rundown of how to get setup:
**Setup**
1. Make sure you have the Go environment setup on your computer. There are quite a few better resources online on how to do that
2. `go get -u -v github.com/matthewmueller/joy/...` to install the compiler from source
3. `go test -v` to run all the tests
**Links and tips:**
- https://astexplorer.net/: I've been using this to figure out how to build the JS tree
- http://goast.yuroyoro.net/ : Simple Go AST viewer
- https://github.com/estree/estree/blob/master/es5.md: Link to the ES3 AST format, this is implemented in [syntax.go](internal/jsast/syntax.go)
- https://golang.org/ref/spec: You may need to refer to this to see what types are possible in Go's AST
- To run all tests: `go test -v`
- To run individual tests: `go test -v -run Test/08`
- `pretty.Println(ast)` will pretty print the JS AST (requires [this package](https://github.com/kr/pretty))
- `ast.Print(nil, node)` will pretty print the Go AST
