# WASM for _Tcell_



You can build _Tcell_ project into a webpage by compiling it slightly differently. This will result in a _Tcell_ project you can embed into another html page, or use as a standalone page.



## Building your project



WASM needs special build flags in order to work. You can build it by executing

```sh

GOOS=js GOARCH=wasm go build -o yourfile.wasm

```



## Additional files



You also need 5 other files in the same directory as the wasm. Four (`tcell.html`, `tcell.js`, `termstyle.css`, and `beep.wav`) are provided in the `webfiles` directory. The last one, `wasm_exec.js`, can be copied from GOROOT into the current directory by executing

```sh

cp "$(go env GOROOT)/misc/wasm/wasm_exec.js" ./

```



In `tcell.js`, you also need to change the constant

```js

const wasmFilePath = "yourfile.wasm"

```

to the file you outputed to when building.



## Displaying your project



### Standalone



You can see the project (with an white background around the terminal) by serving the directory. You can do this using any framework, including another golang project:



```golang

// server.go



package main



import (

	"log"

	"net/http"

)



func main() {

	log.Fatal(http.ListenAndServe(":8080",

		http.FileServer(http.Dir("/path/to/dir/to/serve")),

	))

}



```



To see the webpage with this example, you can type in `localhost:8080/tcell.html` into your browser while `server.go` is running.



### Embedding

It is recomended to use an iframe if you want to embed the app into a webpage:

```html



```



## Other considerations



### Accessing files



`io.Open(filename)` and other related functions for reading file systems do not work; use `http.Get(filename)` instead.
