Provide configurable cookie consent plugin for Alma Career (formerly LMC) products. The package contains predefined Alma Career settings, translations and UI based on Spirit Design System.
The package is a wrapper around Cookie Consent by Orest Bida.
See upgrade guide for upgrade guidance to version 2.0. For complete list of changes see changelog.
Make assets load faster by placing pre-connect headers right after <meta charset> in your <head>:
<link rel="preconnect" href="https://cdn.jsdelivr.net">
<link rel="preconnect" href="https://fonts.googleapis.com">
<link rel="preconnect" href="https://fonts.gstatic.com" crossorigin>
Load default CSS along with your styles in <head>:
<link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Inter:wght@400;600;700&display=swap">
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@lmc-eu/cookie-consent-manager@2/LmcCookieConsentManager.min.css">
Load the script and initialize the plugin right before ending </body> tag:
<script defer src="https://cdn.jsdelivr.net/npm/@lmc-eu/cookie-consent-manager@2/init.js"></script>
<script>
window.addEventListener('DOMContentLoaded', function () {
initLmcCookieConsentManager('demo.example'); // use the name of your service, like jobs.cz, seduo.pl etc.
});
</script>
This will load the plugin from CDN and initialize the plugin with default settings.
As a next step, add a link to open cookie settings after the consent was previously given. This link should be placed somewhere in the page footer, usually near "Terms of use" and "Privacy policy" links.
<a href="" data-cc="c-settings">Open cookie settings</a>
You can load the plugin from a CDN, as in the basic example above.
<!-- Note we use version "cookie-consent-manager@2", which points to the latest version of this series (including feature and bugfix releases) -->
<link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Inter:wght@400;600;700&display=swap">
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@lmc-eu/cookie-consent-manager@2/LmcCookieConsentManager.min.css">
<script defer src="https://cdn.jsdelivr.net/npm/@lmc-eu/cookie-consent-manager@2/init.js"></script>
Alternatively, you can also download the latest version from the Releases page.
Loading the plugin from CDN or static file is recommended mostly for static sites without their own build process.
Once the plugin is loaded, you need to initialize it using initLmcCookieConsentManager() method, optionally providing
configuration parameters.
For projects with their own build process for JavaScript, it is recommended to use the plugin via npm package @lmc-eu/cookie-consent-manager.
Add the plugin to your dependencies:
yarn add @lmc-eu/cookie-consent-manager
or
npm install --save @lmc-eu/cookie-consent-manager
Import the module in your javascript:
import LmcCookieConsentManager from '@lmc-eu/cookie-consent-manager';
window.addEventListener('DOMContentLoaded', function () {
LmcCookieConsentManager('demo.example'/* , optional plugin configuration */);
});
See below for configuration options.
You can also look at the example with EcmaScript module syntax.
Include default CSS in your HTML:
<link rel="stylesheet" href="node_modules/@lmc-eu/cookie-consent-manager/LmcCookieConsentManager.min.css">
or in your Sass stylesheet:
@use "node_modules/@lmc-eu/cookie-consent-manager/LmcCookieConsentManager.css";
Please mind the .css extension used in the Sass example. Using the provided .scss stylesheet is
recommended only for projects that are built with Spirit Design System.
See below for theme customization options.
For projects that are NOT built with Spirit Design System:
Include default font in your HTML:
<link rel="preconnect" href="https://fonts.googleapis.com">
<link rel="preconnect" href="https://fonts.gstatic.com" crossorigin>
<link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Inter:wght@400;600;700&display=swap">
or in your Sass stylesheet:
@import url("https://fonts.googleapis.com/css2?family=Inter:wght@400;600;700&display=swap");
Or switch to custom font that matches the design of your project.
You can also use module with CommonJS import syntax:
const LmcCookieConsentManager = require('@lmc-eu/cookie-consent-manager');
You can also look at the example with CommonJS syntax.
Note: We prefer to use modern ESM import syntax so this is marked as legacy.
With Webpack: Webpack prioritises the ESM import syntax over CommonJS import syntax. So resolve the main field as first: resolve: { mainFields: ["main", /* ... */ ] },
For "necessary" cookies it is not needed to check whether a user has given any consent.
However, for all other purposes, it must be explicitly checked whether user has given the appropriate consent category. This must be done before the respective cookie is set.
In case user rejects some (or all) optional consent categories, you must implement logic to remove current cookies (as well as localStorage) in your product yourself`, this library does not manipulate with the cookies by default.
| Category | Description |
|---|---|
necessary | Strictly necessary cookies are essential for user to browse the website and use its features, such as accessing secure areas of the site. These cookies are first-party cookies. Some examples of strictly necessary cookies: Session cookies, Cookie consent cookies, Load balancing cookies, CSFR tokens, Language selection cookies, Region/country cookies, Performance cookies, Application firewall cookies and JavaScript check cookies. For these cookies you don't need to check whether user actually has this category. |
ad | For cookies related to advertising |
analytics | For analysis and statistics |
functionality | For extended functionality (not covered by necessary category) |
personalization | For personalization based on user profiling (recommendation, etc.) |
GTM scripts are managed centrally in LMC, so if GTM of the product is managed by LMC, after implementing this library, you don't need to worry about conditions when to run them. The library sets all the required data to GTM dataLayer.
However, keep in mind you still need to take care (i.e. delete) of already existing cookies, even of those created by GTM scripts.
To execute custom code which depends on cookie consent use callbacks:
// ...
initLmcCookieConsentManager(
'demo.example',
{
onAccept: (cookieConsent) => {
if (cookieConsent.allowedCategory('functionality')) {
startOptionalFeature();
}
},
}
);
// ...
<script>To automatically load external scripts after a specific consent category is given by the user, modify the <script> tag:
set type to type="text/plain" and add data-cookiecategory attribute with required consent category.
<script src="personalization.js" type="text/plain" data-cookiecategory="personalization" defer></script>
<script type="text/plain" data-cookiecategory="functionality">
console.log('functionality consent given');
</script>
👀 This feature is shown in examples. See also full documentation for this feature.
This feature is enabled by default. If you'd like to disable it, you can do so by overriding page_scripts value in
config option:
initLmcCookieConsentManager(
'demo.example',
{
config: {
page_scripts: false
}
}
);
Optional config parameters could be provided on plugin initialization as the second parameter, encapsulated in the configuration object.
initLmcCookieConsentManager( // when loaded as a module, these options are passed to `LmcCookieConsentManager()` instead
'demo.example', // provide the name of your service, like jobs.cz, seduo.pl etc.
{
defaultLang: 'cs',
autodetectLang: false,
onAccept: (cookieConsent) => {
// custom code
},
translationOverrides: { // overrides of the default translation for specified languages
cs: { consentTitle: 'Vlastní nadpis', descriptionIntro: 'Vlastní úvodní text popisu souhlasu' },
en: { consentTitle: 'Custom title' },
},
cookieTable: { // cookie table for specified languages, shown in settings modal
cs: {

},
}
);
👀 See extended configuration example
| Option | Type | Default value | Description |
|---|---|---|---|
autodetectLang | boolean | true | Autodetect language based on the value of <html lang="...">. If autodetect fails or if unsupported language is detected, fallback to defaultLang.When disabled, force language to defaultLang. |
defaultLang | string | 'cs' | Default language. One of cs, de, en, hu, pl, ru, sk, uk. This language will be used when autodetect is disabled or when it fails. |
companyNames | array | ['Alma Career'] | Array of strings with company names. Adjust only when the consent needs to be given to multiple companies. Value "Alma Career" is replaced with translated legal name. See example. |
consentCollectorApiUrl | ?string | 'https://ccm.lmc.cz/(...)' | URL of the API where user consent information is sent. Null to disable sending data to the API. |
config | Object | {} | Override internal config of the underlying library. For all parameters see original library. |
displayMode | DisplayMode (string) | DisplayMode.FORCE (force) | force (default) to show consent in a centered modal box and to block page until user action. soft to show consent banner on the bottom of the page and do not block the page before user action. |
secondaryButtonMode | SecondaryButtonMode (string) | SecondaryButtonMode. ACCEPT_NECESSARY (acceptNecessary) | Which button should be shown next to "Accept all". acceptNecessary (default) or showSettings (this option also hides link to show settings in consent text). |
on* callbacks | function | (cookieConsent) => {} | See below for configurable callbacks. |
translationOverrides | Record<string, TranslationOverride> | {} | Override default translation for specified languages. consentTitle, descriptionIntro and settingsModalMoreInfo could be overridden.See example |
cookieTable | CookieTable | {} | Define a cookie table (shown in the settings modal) for specified languages and specified categories. See above for example configuration |
Translation of the user interface is provided in the following languages:
bs)cs)de)en)et)hr)hu)lt)lv)mk)pl)ru)sk)sl)uk)👀 See example of each language version
The library can trigger configured callbacks in various events. They can be used to execute custom functionality, for example, to enable some feature after user has given consent.
Each configured callback receives cookieConsent parameter - instance of the underlying cookie consent library,
which can be used to call its methods or retrieve data from the cookie.
| Callback | Trigger event |
|---|---|
onFirstAccept(cookieConsent) | This function will be executed only once, when the user takes the first action (accept all/only selected/only necessary categories). |
onAccept(cookieConsent) | Any consent is detected (either given now or after page load if it was already saved previously) |
onChange(cookieConsent, categories) | Right after the user changes cookie settings. The callback receives also categories object containing arrays of accepted, rejected, and changed categories. |
If your project uses Spirit Design System, you are almost done!
All you need to do is to add this plugin's SCSS to your Sass pipeline and use it instead of the default CSS:
// my-project.scss
// Add this line anywhere you import other third-party CSS, possibly somewhere close
// to the end of your stylesheet as it contains CSS selectors with high specificity.
@use '@lmc-eu/cookie-consent-manager/LmcCookieConsentManager';
node_modules and path to your design tokens in your Sass include paths.Set up Sass load path so the Sass compiler can find stylesheets located in the node_modules directory
(you will already have a path to your design tokens there, as required by Spirit Web):
# CLI command (possibly used in your npm scripts)
sass --load-path=node_modules --load-path=path/to/my/design-tokens my-project.scss my-project.css
Or with webpack:
// webpack.config.js
{
loader: 'sass-loader',
options: {
sassOptions: {
includePaths: [
path.resolve(
__dirname,
'node_modules',
'path/to/my/design-tokens',
),
],
},
},
},
Note: sass v1.23 or higher is required to be able to compile the new Sass modules syntax. You may need to migrate
to sass since all other Sass compilers (and the old @import rule) are now deprecated.
A handful of CSS custom properties are available for you to customize the UI to make it match the design of your site. For example, to change the text color of cookie consent UI, load the default CSS and add the following code anywhere in your stylesheet (the order of which is not important):
:root {
--lmcccm-text: #333;
}

Default cookie consent design uses Inter font loaded via Google Fonts as shown in the basic example. If you are not using cookie consent with the default design, additional steps may be necessary for you:
:root {
--lmcccm-font-family: "Open Sans", arial, sans-serif;
}
If you use a custom font like this, make sure you don't load the default Inter font and that you use
<link rel="preconnect" ...> only to actually needed domains.
