The best way to Use Storage in Net Extensions

Engaged on an internet extension is an attention-grabbing expertise — you get to style internet whereas working with particular extension APIs. One such API is storage — the net extension taste of persistence. Let’s discover how you should use session and native storage inside your Manifest V3 internet extensions!

Enabling Extension Storage

The extension storage API is not out there by default. To allow the storage API, it is advisable to cite it within the manifest.json file of your extension:

{
  // extra....
  "manifest_version": 3,
  "identify": "__MSG_appName__",
  "permissions": [
    "storage",
    // more....
  ],
  // extra....
}

Including storage to the permissions array, which is a prime degree manifest.json key, gives session and native storage capabilities to your extension.

Get, Set, and Take away Storage Values

Very like conventional localStorage and sessionStorage APIs, extension storage gives get, set, and take away operations:

// set
await chrome.storage.session.set({ identify: "David", shade: "inexperienced" });

// get 
const { identify, shade } = await chrome.storage.session.get(["name", "color"]);

// take away
await chrome.storage.session.take away(["name", "color"]);

Just a few issues to notice:

• get requires an array argument, not a single worth like localStorage and sessionStorage
• set must be an object format
• take away can be an array, very similar to get
• You need to use chrome.storage.native or chrome.storage.session relying on how
• All the extension storage API strategies are promise-based, with await or callback codecs

Clear All Storage

Within the occasion that you simply need to clear all knowledge for native or session storage, there is a clear technique:

await chrome.storage.session.clear();

Utilizing clear is efficient however you will need to make sure that you do actually need to clear all the things — clear might develop into a upkeep problem.

Storage is an important a part of most internet extensions. Whereas the API is easy, the async format and technique names are totally different.
