Example of embedding a Vue application inside a Go binary. Here we explore how a project might be structured and built. The Vue application is bootstrapped using Vue CLI (v3).

Development is done in the /front-end directory

Development is done in the root directory

The following steps are necessary to make the Vue build work as an embedded resource inside the Go binary. We have to make it so that the paths that will be in the frontend-assets.go are located off the same directory as the Go source. For example

"/index.html": {	local: "index.html",	size: 772,	modtime: 1534702974,	compressed: ` H4sIAAAAAAAC/4ySz24TMRDGX2XIpRd2nZQ2bSTbEio9wIVKgIDjxJ6N3Ti2sWc3ytuj7ob0jwD1YmnG 329mPJ/lmw+fb77+vLsFx7ug5cMJAeNGUdTSEVotd8QIxmGpxKrnrrk+5hxzbuhX7wf1o/n2vrlJu4zs 14HApMgUWc0+3iqyG5odkYg7UoOnfU6FH1V7b9kpS4M31IzBWx89ewxNNRhILWZaBh+3UCgob1IEV6hT osPhIWq9SVqy50C6KylyQ9FKMSUmcNLfV4Hr1HN7sVqdz1dX8/a+jjVzoY7YuGdqU6vAnNvl4vxisbjC 1tSTOiS0gFVVPvylR84tXa4MXS/Nkw4nxhSf+SVkXB+3zUDRplJbnHfzy3dL+zr8n5OO41VHxFqKyc91 sgctY/pTpnJJcaO/01khqKmUA6x7htMewSaq8Yxhn8oWckmZSjjA3rNLPcMnHPDLWAoo4jqQbeEuEFY6 xuAZOI1m+9hTK8WxoxSPQ1g/gLcKc9ZSWD9oOd1ALeb/29FSnF7yHHnhwhOhmHYgxk//OwAA///aDgFu BAMAAA== `, 

index.html is in the same directory as main.go. Assets are in /css, /img, and /js respectively.

Vue is built using npm run build. The resulting /dist directory is copied to the /build-workspace directory.

• copy the *.go files and relevant go subdirectories to the /build-workspace/dist created from the Vue build process. The objective is to make sure the main entrypoint to the Go program is in the same directory as the entry point (index.html) of the Vue application.
• run go generate to generate the frontend-assets.go source that will contain the Vue application assets that will be embedded into the binary. Specifics of the embedding and code generation are in the main.go file. For example, a //go:generate esc -o frontend-assets.go -pkg main index.html favicon.ico js css img appears on the top of main.go.
• run go build -o go-vue-embedded frontend-assets.go main.go to create the binary

Run the go-vue-embedded binary. Open up the browser to http://127.0.0.1:4022/#/. The # is due to Vue router's default mode.

• create a makefile for the entire build process
