IPLD formats are overwritten in nodejs

[oed]

• Version: 0.46.0

• Platform: nodejs

• Subsystem: ipld

Severity: Low

Description:

When specifying a custom ipld format when creating an ipfs instance the default formats get overwritten. This seems to be happening since the default formats are not defined in the nodejs config for ipld: https://github.com/ipfs/js-ipfs/blob/master/packages/ipfs/src/core/runtime/ipld-nodejs.js (Ipld just uses the passed formats array without merging with it's defaults)

In the browser config it looks like it should work since the passed formats array should be merged with the default one, but I have not confirmed.

Steps to reproduce the error:

Run this in nodejs with a custom myFormat.

const ipfs = await Ipfs.create({ ipld: { formats: [myFormat] } })
