# OFDGo [](https://pkg.go.dev/github.com/xiaoqidun/ofdgo)
|
||
首个原生、全平台兼容的纯 Go 语言 OFD 读写库
|
||
|
||
|
||
# 在线体验
|
||
[OFDGo WebUI](https://ofdgo.aite.me/)，将OFDGo编译为WASM提供服务
|
||
|
||
# 一键部署
|
||
```shell
|
||
docker run -d -p 80:80 ccr.ccs.tencentyun.com/xiaoqidun/ofdgo:latest
|
||
```
|
||
|
||
# 构建指南
|
||
```batch
|
||
:: 1. 编译OFDGo WASM
|
||
set GOOS=js
|
||
set GOARCH=wasm
|
||
go build -o assets/webui/ofdgo.wasm -trimpath -ldflags "-s -w -buildid=" ./cmd/webui/wasm.go
|
||
:: 2. 编译OFDGo WebUI
|
||
set GOOS=windows
|
||
set GOARCH=amd64
|
||
go build -o ofdgo_webui.exe -trimpath -ldflags "-s -w -buildid=" ./cmd/webui/webui.go
|
||
```
|
||
|
||
# 安装为库
|
||
```shell
|
||
go get -u github.com/xiaoqidun/ofdgo
|
||
```
|
||
|

# 渲染输出
|
||
```go
