echartsgoja renders Apache ECharts as SVGs using the
goja JavaScript runtime. Developed for use by usql for
rendering charts.
Install in the usual Go fashion:
$ go get github.com/xo/echartsgoja@latestThen use like the following:
package echartsgoja_test
import (
"context"
"log"
"os"
"github.com/xo/echartsgoja"
)
func Example() {
echarts := echartsgoja.New()
svg, err := echarts.RenderOptions(context.Background(), simpleOpts)
if err != nil {
log.Fatal(err)
}
if err := os.WriteFile("simple.svg", []byte(svg), 0o644); err != nil {
log.Fatal(err)
}
// Output:
}
const simpleOpts = `{
"xAxis": {
"type": "category",
"boundaryGap": false,
"data": ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"]
},
"yAxis": {
"type": "value"
},
"series": [{
"data": [820, 932, 901, 934, 1290, 1330, 1320],
"type": "line",
"areaStyle": {}
}]
}`- Rewrite as native Go
echartsgoja was written primarily to support these projects:
- usql - a universal command-line interface for SQL databases
Users of this package may find the github.com/xo/resvg package
helpful in rendering generated SVGs.
