fix: avoid require bug in node.js 13.0

[bluelovers]

nodejs/modules#446

"Error: Package exports for '/data/data/com.termux/files/home/.config/yarn/global/node_modules/nanoid' do not define a valid '.' target\n"

@bluelovers dual-publish automatically inserts main to package.json during the publish.

How I can reproduce your issue?

[bluelovers]

this pr is failed, it can't fix this issue

but if i edit inretface-datastore/src/key.js

replace nanoid to nanoid/index will not have this error at start up
but i can't replace it at every where

---

install termux on android phone
install git and nodejs , yarn
nodejs will be 13.0.0 <== new version didn't have this issue, but termux only have this version

yarn global add novel-opds-now
novel-opds-now

don't use npm install this
will see this error

i also try request termux update nodejs too, but not sure they will see my email xd

It happens because Node.js 13 does not support conditional exports. Look at node_modules/nanoid/package.json.

You can enable it manually by running node --experimental-conditional-exports.

@ai But it does support. Just emits warning.

@TrySound there were some bugs in old Node.js 13.0 versions.

I think we should support only the latest version of each Node.js 10.x, 12.x, and 13.x branches.
