Context

We use contentful/live-preview. The library has graphql-js as a dependency.

Problem

If the DOM has an element with id="process" eg. <div id="process"></div> than the current implementation of utils/instanceOf would fail.

Current implementation:

globalThis.process != null && globalThis.process.env.NODE_ENV === 'production'

with this implementation globalThis.process will return the DOM element:
image

Because globalThis.process is true, the condition globalThis.process.env.NODE_ENV === 'production' gets executed and will result with an javascript error:

Doing it this way will still allow bundlers to remove this condition when process.env.NODE_ENV gets removed by i.e. the replace-plugin

Suggested change
globalThis?.process?.env?.NODE_ENV === 'production'
globalThis.process != null && globalThis.process.env != null && globalThis.process.env.NODE_ENV === 'production'

this currently is a breaking change in the 16.x.x release line which is
preventing folks from upgrading towards a security fix. This PR should
result in a patch release on the 16 release line.

This change was originally introduced to support CFW and browser
environments which should still be supported with the `typeof` check CC
@n1ru4l

This also adds a check whether `.env` is present as in the DOM using
`id="process"` defines that as a global which we don't want to access on
accident. as shown in #4017

Bundles also target `process.env.NODE_ENV` specifically which fails when
it replaces `globalThis.process.env.NODE_ENV` as this becomes
`globalThis."production"` which is invalid syntax.

Fixes #3978
Fixes #3918
Fixes #3928
Fixes #3758
Fixes #3934

This purposefully does not account for
#3925 as we can't address
this without breaking CF/plain browsers so the small byte-size increase
will be expected for bundled browser environments. As a middle ground we
did optimise the performance here. We can revisit this for v17.

Most bundlers will be able to tree-shake this with a little help, in
#4075 (comment)
you can find a conclusion with a repo where we discuss a few.

- Next.JS by default replaces
[`process.env.NODE_ENV`](https://github.com/vercel/next.js/blob/b0ab0fe85fe8c93792051b058e060724ff373cc2/packages/next/webpack.config.js#L182)
you can add `typeof process` linearly
- Vite allows you to specify
[`config.define`](https://vitejs.dev/config/shared-options.html#define)
- ESBuild by default will replace `process.env.NODE_ENV` but does not
support replacing `typeof process`
- Rollup has a plugin for this
