An Announcement Banner that is lightweight and based on tailwindcss for the styling
The announcement bar uses native methods to make the library lightweight so that it can be loaded quickly, bar the webpack stuff.
Note The initial version makes use of the WordPress API to be able to get the latest post.
i.e. it expects a json structure like so:
From a url like http://blog.example.com/wp-json/wp/v2/posts?per_page=1&_fields=id,title,link
[
{
"id": 175,
"link": "https:\/\/blog.example.com\/how-to-hunt-a-vole\/",
"title": {
"rendered": "How To Hunt A Vole"
}
}
]I plan to add more options and a parser callback that can be defined to extract a standard format.
You can install the package via npm:
npm i @reecem/h-barOr use jsDelivr:
...
<script src="https://unpkg.com/@reecem/h-bar?umd"></script>
...If you are customising the styling and overriding it with your own styling then you will also need an instance of your css or a tailwindcss file installed as only the classes needed are packaged with h-bar
You can import it directly into your javascript app or use it in the html.
<script src="../hBar.js"></script>
<!-- or -->
<script src="https://unpkg.com/@reecem/h-bar?umd" defer></script>
<script>
hBar.init({
url: "http://blog.example.com/wp-json/wp/v2/posts?per_page=1&_fields=id,excerpt,title,link",
secondaryLinks: [
{
title: "Docs",
link: "http:://docs.example.com"
},
{
title: "Support",
link: "http://help.example.com"
}
],
options: {
theme: "blue",
}
});
hBar.fetchData()
</script>The initialization object currently has this structure and defaults:
{
url: "https://your.blog/api/....",
onCompleted: "callback function",
link: "The link url, can be force and no need to fetch from API",
title: "The link url, can be force and no need to fetch from API",
secondaryLinks: [
{
title: "Docs",
link: "http:://docs.example.com"
}
],
parser: (data) => {/** Parser function */}
dismissible: false, // dismissible banner flag
dismissFor: new Date('2020-03-30'), // would dismiss it till end of March 30th 2020
theme: "gray",
headers: {
"Authorization": "Bearer {TOKEN}"
},
customStyles: {
wrapper: "hb-flex hb-w-full hd-flex-col md:hb-flex-row sm:hb-flex-row hb-text-sm hb-py-2 md:hb-px-20 hb-px-1 hb-items-center hb-justify-between",
linkWrapper: "hb-flex hb-items-center",
badge: "hb-px-2 hb-mx-2 hb-leading-relaxed hb-tracking-wider hb-uppercase hb-font-semibold hb-rounded-full hb-text-xs",
postTitle: "hover:hb-underline",
secondaryLink: "hb-mx-5 hb-cursor-pointer hover:hb-underline",
}
}Theme colors available: gray, lightGray, blue, green, indigo, orange, yellow, teal, red
(the below images are in the order they exits)
There is the availability of adding a custom parser function to override any of the default ones provided by the package.
This is handy if you have a custom endpoint that say would return also the secondary links or has a different data structure.
The parser function should always return an object with the structure:
{
title: String,
link: String,
/** the secondaryLinks is optional.
* It will also override the links parsed in the init() arguments.
*/
secondaryLinks: [
{
title: String,
link: String,
},
]
}You can define the function inside the init() method as follows:
hBar.init({
url: "https://api.github.com/repos/ReeceM/h-bar/releases",
parser: (data) => {
// getting the first release on the list of releases from github.
const {name, html_url} = data[0];
return {
title: `Lateset version available ${name}`,
link: html_url
};
}
})Available from
v0.3.0/v1.0.0
Temporary Dismissing To be able to dismiss a notification, please note it currently removes secondary links. It is therefore useful that you use this feature when just making announcements of a event or brief notification.
The way to activate session based dismissal is:
{
//... rest of config
dismissible: true,
//... rest of config
}This will just disable the banner for the current page visit, if the user reloads, its back.
Time based dismissing
To dismiss the banner until another time, you can set the dismissFor variable, this requires a Date() object.
When you set this and the banner is dismissed, the UTC milliseconds are stored in the localStorage, this is then read back when loading h-Bar.
{
//... rest of config
dismissible: true,
dismissFor: new Date('2020-03-30'), // would dismiss it till end of march 30th
}If you fail to set the value properly, it won't dismiss and the banner will show by default.
to come please make a PR if you know how to do it on JS.
