Node 12 support dropped with #3245

[mitchellbusby]

• Version:

IPFS 0.5+

• Platform:

N/A - not platform specific

• Subsystem:

N/A - ipfs core related

Severity:

High/Medium

Description:

merge-options dropped support for Node 12 with their 3.x release, which IPFS just bumped up. This causes Node 12 install to fail.

Raising on the off chance this was missed -- it might be entirely intentional.

Steps to reproduce the error:

Try to install ipfs under node 12 -- the install of merge-options will fail.

Not sure how severe this actually is -- was a minor annoyance for me -- there may not actually be an intention to support node 12 at this stage, but I was surprised since it's the current LTS variant.

We run CI under node 12 which passes (docker publish step notwithstanding) and I can't replicate this locally. What's the error you are seeing?

@achingbrain Node.js 12 LTS, first install ipfs-http-client v46.0.1, then upgrade it to v46.1.0, you will get:

error merge-options@3.0.1: The engine "node" is incompatible with this module. Expected version ">=14". Got "12.18.3"
Done in 10.69s.

Are you running with engine-strict = true?

[achingbrain]

Ah, yarn.

[achingbrain]

It's a bit tedious, merge-options does have engines >= 14 in it's package.json since it's been rewritten to esm modules but is also published transpiled to common js and doesn't use any node 14 features, hence no CI failure.

[mitchellbusby]

Ahhh that makes sense - I was also using yarn 😅

[mitchellbusby]

@achingbrain is it possible to drop down to the previous version or is that a needed peer dep?

[mitchellbusby]

(To be clear this isn’t pressing for me - I’m stuck on older versions by way of OrbitDB)

[achingbrain]

Yes, I'll downgrade and publish a new version.

Fixed in ipfs@0.50.1
