View supported versions of node

The NodeJS core team provides a JSON file in nodejs/release: https://github.com/nodejs/Release/blob/main/schedule.json which details all of the major versions of Node, their initial release date, EOL, maintenance mode date, as well as LTS date.

I wanted to do a test run with this document of parsing it and getting some initial results. As Node 10 went EOL at the end of today, I thought it could be neat to use this to track node versions in projects you work on and if you're using a node version that is no longer supported, it could inform you of such and tell you to upgrade to the latest LTS. As a test run, I pull down the JSON file and parse it out to list the versions of Node which are still being supported.

(Also as a fun aside, I am tending more and more of using arg() to display a list of content even if I don't then select one & go further with it. I enjoy the way it presents the data & it is filterable by default. I know of the img and html fields are around but I have yet to find neat ways of using them.)

Code:

// Menu: Available Node versions
// Description: View all supported versions of NodeJS
// Author: Benjamin Lannon

let resp = await get(
  "https://raw.githubusercontent.com/nodejs/Release/main/schedule.json"
);
const data = Object.entries(resp.data);

/** @type typeof import('dayjs') */
let dayjs = await npm("dayjs");

let opts = [];

for (let [version, info] of data) {
  let isSupported =
    dayjs(info.start).diff(dayjs(), "days") < 0 &&
    dayjs(info.end).diff(dayjs(), "days") > 0;

  if (isSupported) {
    opts.push({
      name: `Node ${version}`,
      description: `Maintainence ends on ${dayjs(info.end).format(
        "MMMM DD, YYYY"
      )}`,
      endDate: info.end,
    });
  }
}

opts = opts.sort((a, b) => {
  return dayjs(a.endDate).unix() - dayjs(b.endDate).unix();
});

await arg("These versions of NodeJS are currently maintained", opts);
