goja-babel
Uses github.com/dop251/goja to run babel.js within Go.
WARNING: This uses Babel v6.26 which is not the latest. Feel free to create a PR updating it to the latest.
WARNING: This is largely untested and the exposed API may change at any time.
Usage
package main
import (
"fmt"
"io"
"os"
"strings"
"github.com/jvatic/goja-babel"
)
func main() {
babel.Init(4) // Setup 4 transformers (can be any number > 0)
res, err := babel.Transform(strings.NewReader(`let foo = 1;
<div>
Hello JSX!
The value of foo is {foo}.
</div>`), map[string]interface{}{
"plugins": []string{
"transform-react-jsx",
"transform-es2015-block-scoping",
},
})
if err != nil {
panic(err)
}
io.Copy(os.Stdout, res)
fmt.Println("")
}
var foo = 1;
React.createElement(
"div",
null,
"Hello JSX! The value of foo is ",
foo,
"."
);

Functions ¶
func Asset ¶
Asset loads and returns the asset for the given name. It returns an error if the asset could not be found or could not be loaded.
func AssetDir ¶
AssetDir returns the file names below a certain directory embedded in the file by go-bindata. For example if you run go-bindata on data/... and data contains the following hierarchy:
data/
foo.txt
img/
a.png
b.png
then AssetDir("data") would return []string{"foo.txt", "img"} AssetDir("data/img") would return []string{"a.png", "b.png"} AssetDir("foo.txt") and AssetDir("notexist") would return an error AssetDir("") will return []string{"data"}.
func AssetInfo ¶
AssetInfo loads and returns the asset info for the given name. It returns an error if the asset could not be found or could not be loaded.
func MustAsset ¶
MustAsset is like Asset but panics when Asset would return an error. It simplifies safe initialization of global variables.
func RestoreAsset ¶
RestoreAsset restores an asset under the given directory
func RestoreAssets ¶
RestoreAssets restores an asset under the given directory recursively
