Encodeuricomponent() - Javascript | Mdn


Here's my thought on encodeURIComponent() - JavaScript | MDN

In order to send data that includes special characters such as / in a url you need to url encode it. You have probably seen these many times in urls with things like %20 for spaces.

I'm working on a chrome extension to make quick blog posts, like thoughts or a persistent bookmark tool with comments. The backend is written in fastapi and when I check to see if I have a post for a page I need to url encode it.

curl -X 'GET' \
  'https://thoughts.waylonwalker.com/link/?link=https%3A%2F%2Fhtmx.org%2Fextensions%2Fclient-side-templates%2F' \
  -H 'accept: application/json'

curl example generated from the fastapi swagger docs.

Here is how I used javascript's encodeURIComponent to turn my chrome extension into a notification when I already have a post for the current page.

// Event listener for tab changes
chrome.tabs.onActivated.addListener(function (activeInfo) {
  // Get the active tab information
  chrome.tabs.get(activeInfo.tabId, function (tab) {
    const url = tab.url || "";

    getData(`https://thoughts.waylonwalker.com/link/?link=${encodeURIComponent(url)}`).then((data) => {
        console.log('link data: ', data);
      if (data.hasOwnProperty('detail')) {
        chrome.browserAction.setBadgeText({ text: "" });
      } else {
        localStorageKey = `formData-${url}`;
        chrome.browserAction.setBadgeText({ text: "1" });
        chrome.browserAction.setBadgeBackgroundColor({ color: "#80A3D5" });
        localStorage.setItem(localStorageKey, JSON.stringify(data));
