    Library that helps you create HTML Alert.

    All the precreated alert


    You need node.js and npm and fp-dom-tool.

    npm install fp-dom-alert

    import _tool from "fp-dom-tool"; // opt.
    import _alert from "fp-dom-alert"; // lib fp-dom-alert
    const _export = {
    export default _export;

    To export the Style

    • In you config.webpack.js:
    module: {
      rules: [
          test: /\.css$/,
          use: [
              loader: "style-loader",
              loader: "css-loader",
              options: {
                modules: true,
    • In you scss or css file:
    @import "fp-dom-alert/lib/index.css";


    • You need to create an html container with a class ._message. You can use the function _createElement from the fp-dom-tool package.
    const _messageContainer = _tool._createElement("div")(["class", "_message"]);
    • Create an alert with the function _alert. The function required two arguments: an alert type and and content. The package has 3 alert pre-created.
    const _alertDanger = _alert._alert("danger");
    const _alertSuccess = _alert._alert("success");
    const _alertWarning = _alert._alert("warning");
    • You then append all you alert to the ._message container by using the function _appendElement.
    const appendMessageContainer = _tool._appendElement(_messageContainer);
      _alert._alertDanger("Something is wrong"),
      _alert._alertWarning("Better be carefull"),
      _alert._alertSuccess("All is fine now")
    • The ._message container is by default on display:none. You can use the function _switchElementDisplay from the from the fp-dom-tool package. Everytime the _switchElementDisplay is used the element changes state from display:none to display:block.
    const _switchAlertDisplay = _tool._switchElementDisplay(_messageContainer);
    _switchAlertDisplay(); // display:block
    _switchAlertDisplay(); // display:none


    Each pre-created alert has the following style:

    @import url("https://fonts.googleapis.com/css2?family=Montserrat:ital,wght@0,200;0,300;0,400;0,700;1,200;1,300;1,400;1,700&display=swap");
    $message-danger: #f8d7d9;
    $message-success: #d4edd9;
    $message-warning: #fff3cd;
    @mixin message($color) {
      background-color: $color;
      border-color: darken($color, 50);
      color: darken($color, 50);
    ._message {
      display: none;
      &__container {
        padding: 0.6rem;
        border: 2px solid #000;
        border-radius: 0.3em;
        font-family: "Montserrat", sans-serif;
        font-size: 1.1rem;
        margin: 0.3rem 0;
      &--danger {
        @include message($message-danger);
      &--success {
        @include message($message-success);
      &--warning {
        @include message($message-warning);

    Changing style

    Direclty in css

    You can overide the predifined with yours by creating your own style.

    By using the library

    You can also use the function _createAlertStyle from this package. First you need to create an object that will overide the _AlertCss object. The _AlertCss has the following property:

    const _AlertCss = {
      padding: ".6rem",
      border: "2px solid #000",
      borderRadius: "0.3em",
      fontFamily: "'Montserrat', sans-serif",
      fontSize: "1.1rem",
      margin: "0.3rem 0",
      backgroundColor: "#fff",
      borderColor: "#000",
      color: "#000",

    You can't add additional property to the object. Any property not listed in the _AlertCss won't be added.

    const newStyle = {
      backgroundColor: "#9da3d8",
      color: "#2835ad",
      borderColor: "#2835ad",
    const alertInfoStyle = _alert._createAlertStyle(newStyle);

    You can then use the function _setStyle to set the new style to a given element.

    const dangerAlert = _tool._getElementClass("_message--danger");


    // Create the div ._message container that will contain all the alerts.
    const _messageContainer = _tool._createElement("div")(["class", "_message"]);
    const appendMessageContainer = _tool._appendElement(_messageContainer);
    // Create a new type of alert: alertinfo
    const alertInfo = _alert._alert("info");
    // Add a message to the newly alertinfo and append it to the div ._message container.
    appendMessageContainer(alertInfo("Fun Fact: I'm an info"));
    //creste a new style with the element you wish to override.
    const newStyle = {
      backgroundColor: "#9da3d8",
      color: "#2835ad",
      borderColor: "#2835ad",
    // create a new object style
    const alertInfoStyle = _createAlertStyle(newStyle);
    // get the alert alertInfo in the dom and set the new style
    const info = _tool._getElementClass("_message--info");
    // display the alert
    _switchAlertDisplay(); // display:block

    The alert now is now created.
