buffer: implement buffer.atob and buffer.btoa #37529

jasnell · 2021-02-26T18:02:40Z

Web Platform atob and btoa impl.

Just an initial get it working impl, not performance optimized.

Kinda feeling "meh" on repeating the web's mistakes, but I can see the point for web compat.

doc/api/buffer.md

benjamingr · 2021-02-27T12:40:22Z

I also don't really see the point for this API in Node.js, especially since ours (.toString on buffer) is arguably better and this API does not actually improve web compatibility by much since it's not global (and global probably isn't worth the breakage)

jasnell · 2021-02-27T14:36:11Z

Yep. It's been a long standing open feature request, and is implemented in other platforms, it was a quick impl so I figured let's see what the reaction is. I'm fine with not having this either. I'll close this and close the feature request issue as a #wontfix.

jasnell · 2021-03-17T17:52:27Z

I'm reopening this as I've had three separate, independent conversations with different folks in the past two weeks about the lack of atob/btoa in core. Yes, it's not as good as what we already have, and no, I don't see it as being critical, but the implementation is simple and easily maintained and it does improve cross-platform interop.

ljharb · 2021-03-17T17:54:11Z

@jasnell why couldn’t they be globals? (I’m sure there’s discussion somewhere, but I’d love to read it linked from here)

jasnell · 2021-03-17T18:05:06Z

Globals are semver major. If this lands I'll open a separate commit adding that. But this way it allows us the option of backporting the basic impls to 15 and 14

ljharb · 2021-03-17T18:05:57Z

awesome, sounds like a great plan

Just making sure this doesn’t land until it has a big, bold warning against using it (or deprecation notice, tbh – I’d personally say that introducing this as a deprecated feature from the start would be just fine, but I’m guessing not everybody’s on the same page there…)

jasnell · 2021-03-17T18:27:05Z

I'd be -1 for introducing as deprecated but I'm definitely adding a notice in the docs as suggested. I definitely say we need a new status indicator in the docs that Is-Not-Deprecated-But-Is-Also-Not-Recommended

ljharb · 2021-03-17T18:31:33Z

The JS spec is going to use the term "legacy" for "things that are icky that we wish we could get rid of", if that helps :-)

jasnell · 2021-03-17T18:33:01Z

That does help, actually. There are a few APIs in core that are currently deprecated but really fall under that legacy category instead. I may have to open a PR adding that in as an option

lib/buffer.js

+
+const lazyInvalidCharError = hideStackFrames((message, name) => {
+  if (DOMException === undefined)
+    DOMException = internalBinding('messaging').DOMException;


why do we always have to lazily load this constructor?

Yeah, it's gotten a bit out of hand really. I'm doing it for consistency. I recently landed a PR that updated the various AbortError instances to eliminate this in multiple places but there are still more. What would be good is a PR that moves DOMException into `internal/errors' and replaces these lazy loads for that.

benjamingr · 2021-03-18T07:51:26Z

I'm still -0 on this (since right now we're just adding the bad methods without improving compatibility since they're not global) but I see the merit if they're global in the next major.
