Instead of using localStorage/sessionStorage all over the code, the better solution is to create a wrapper for such operations (in my opinion). https://www.geodev.me/blog/typescript-wrapper-class-for-browser-storage04 Jan 2026 16:35 +0000at://did:plc:5bgdexnlihj6kaw2pk7bl64k/app.bsky.feed.post/3mbme5w4rmk2ihttps://bsky.app/profile/muszynov.bsky.social/post/3m3nj3dq7o222I finally forced myself to write a post on a technical topic: How to use infer keyword in Typescript. It's not the easiest part of TypeScript, but it's worth a look. Boris Cherny's book was very helpful. https://www.geodev.me/blog/how-to-use-the-infer-keyword-in-typescript20 Oct 2025 19:05 +0000at://did:plc:5bgdexnlihj6kaw2pk7bl64k/app.bsky.feed.post/3m3nj3dq7o222https://bsky.app/profile/muszynov.bsky.social/post/3m3kcq6y4bs2uFor me, Lovecraft is one of the few writers who can create an atmosphere of fear.
