Node.js hands‑on posts
Practical Node.js learning showed up in social posts: a ChaiCode session on ImageKit and Node file handling circulated (about 33 likes), and a Liveblocks example demonstrated realtime feeds implemented with Node.js. Both posts link to code‑forward tutorials and examples shared this week. (x.com) (x.com)
Node.js learning posts this week centered on code people can run: one ChaiCode project walked through image uploads and file handling, and one Liveblocks example showed realtime feeds wired up with Node.js. (github.com) (liveblocks.io) Node.js is the JavaScript runtime developers use on the server, where it handles jobs like receiving uploads, saving files, and sending updates to browsers. The ChaiCode repository published this week teaches an “Image Upload API” with Express, MongoDB, multer for multipart uploads, sharp for thumbnails, and file system operations such as read, write, and delete. (github.com) The same ChaiCode project breaks the work into concrete pieces: upload routes, download and delete controllers, an ObjectId validator, thumbnail utilities, Docker setup for MongoDB, and six visible test files covering health, connect, upload, list, download, and delete. (github.com) ImageKit sits on the media side of that workflow. Its Node.js software development kit supports file upload, file management, URL generation, and image transformations, and the GitHub repository for the SDK shipped version 7.4.0 last week. (npmjs.com) (github.com) On the realtime side, Liveblocks published a new Feeds primitive on April 6 that stores chat messages or activity logs inside collaborative rooms. Its documentation shows a Node.js example that creates a feed with `@liveblocks/node`, adds a message from the back end, and then renders updates live in React with `useFeedMessages`. (liveblocks.io 1) (liveblocks.io 2) Liveblocks also paired Feeds with Presence, which lets an agent or back-end process appear in a room with a name, avatar, and status data while it works. The same April 6 launch added JSON Patch support for Liveblocks Storage, so a server can send targeted changes instead of rewriting an entire object. (liveblocks.io) Those two posts landed as platform vendors and educators keep packaging Node.js around visible outcomes instead of abstract syntax. ChaiCode’s repository teaches file uploads, validation, and cleanup; Liveblocks’ guide teaches back-end feed creation and front-end live updates. (github.com) (liveblocks.io) The through line is practical server work: move a file from a browser into storage, or move a message from a Node.js process into a room that updates in realtime. Both examples reduce Node.js to a short path from request to result, which is exactly what made them circulate. (npmjs.com) (liveblocks.io)
