  • Cannot figure out how to mock ES6 modules for a Node AWS Lambda
    2 projects | /r/node | 4 Jun 2023
    ESM modules need custom loaders for mocking. Testsouble (https://www.npmjs.com/package/testdouble) was one of the first frameworks to support it AFAIK and a great type-safe option.

  • Testing Without Mocks
    1 project | news.ycombinator.com | 21 Feb 2023
    I’m not sure I manage to follow the author correctly, but to me it seems that by “mock” they strictly refer to external mocking libraries, in the sense of JS’s `testdouble` [1] or Java’s `Mockito` [2]. The fake object as returned by `LoginClient.createNull().getUserInfo(...)` appears to be a “Nullable” for them.

    If you need an alternative for mocking, testdouble.js has full ES module support thanks to some excellent work by Gil Tayar.

  • Bringing Forward the End-of-Life Date for Node.js 16

    The dates were known in advance - however, the Node team expected OpenSSL 3 to be out before the release of Node 16, but it didn't happen - so they had to release with OpenSSL 1.1.1. Between the lines, I think that there was some minor hope of maybe upgrading, but obviously it was to difficult.

    I didn't know what this was referring to so I looked it up.

    Here's a Reddit thread which seems to be the genesis of the complaint (an archive link because the actual post was removed):

    If Node.js 12.x and 14.x releases have full support for ES modules, what gives? I was wondering the same, so I asked Matteo Collina on Twitter (he's a member of the Node.js TSC). Myles Borins (also a member of the TSC) chimed in on the thread to explain the rationale behind ES modules being marked as 'Experimental' in the 12.x and 14.x release lines:
