gitTagJsonOutput.js

// import lib to execute shell
const shellExec = require('shell-exec')

// build shell command to get tags with subject and date
const gitCommand = ` \
        git tag -l \
            --format='{\n
            "tag": "%(tag)", \n \
            "subject": "%(subject)", \n \
            "created": "%(creatordate)" \n \
        },'\
    `
shellExec(gitCommand).then(res => {
    // return array with tag objects
    let jsoned = JSON.parse(`[ ${res.stdout.slice(0, -2)} ]`)
    // console.log(jsoned)
    return jsoned
