Utility lib to simplify implementation of IMID related views, such aas 'sign in', 'Unauthorized', 'Session expired' etc.

const fs = require('fs')
const path = require('path')

// Todo, add some validation of settings object
// Add error handling

const getHTMLForUnitSwitch = settings => {
    const htmlString = getHTMLString(path.resolve(__dirname, 'unitswitcher.html'))
    return injectSettingsObject(settings, htmlString)
}

const getHTMLForUnauthorized = settings => {
    const htmlString = getHTMLString(path.resolve(__dirname, 'unauthorized.html'))
    return injectSettingsObject(settings, htmlString)
}

const getHTMLForLoginExpired = settings => {
    const htmlString = getHTMLString(path.resolve(__dirname, 'loginexpired.html'))
    return injectSettingsObject(settings, htmlString)
}

const getHTMLString = filePath => {
    const htmlFileContent = fs.readFileSync(filePath, 'UTF-8')
    return htmlFileContent.toString()
}

const injectSettingsObject = (settings, htmlString) => {
    return htmlString.replace(
        '<script type="replace-before-render"></script>',
        `<script>window.settings = ${JSON.stringify(settings)}</script>`
    )
}

    getHTMLForUnitSwitch,
