I noticed that:

- The web and electron versions of our `uuid` module both looked exactly
the same…
- …and deferred to the `uuid` package…
- …and the async version just called the sync API.

So now we will just use the `uuid` package directly everywhere.

Just removing some unused/unnecessary scripts and `IS_BETA` env variable
+ the associated code (we don't use this in the OS version of Actual).

Based on Tom's comment
(https://github.com/actualbudget/actual/pull/1058#issuecomment-1568030881

)
I've eliminated all direct use of date-fns and only use the functions in
months.ts.

I've updated the return values in `sync/index` to sensible values based
on how they're being called.

I've updated the type of `msg.value` to be `string | number | null` to
match the values expected by `serializeValue`

- New linter rules are now added
- Perhaps the `createPayee` method i've tagged with a disable should be
deleted.
- I have ignored unused methods in Plaid/Mobile as this stuff is still
WIP/experimental?

Last one before I add the actual linter rules!

Following on from #1146 this PR removes all unused exports from
`loot-core/`

This reverts #1029. As raised in #1097, the formatting chosen doesn’t
work well when doing math. There may be a way to balance compatibility
with multiple format styles with handling non-currency amounts
correctly, but it will require some more careful consideration. Re-opens
#894.

Depends on https://github.com/actualbudget/docs/pull/202.

Closes #944, closes #532. ~WIP because something is causing the test
budget to fail to create because it’s using INSERT instead of UPDATE sql
queries. (Or not? I have no idea)~

Updates to the latest version of electron and moves the backend-frontend
communication from node-ipc to websockets. This resolves the previous
roadblock regarding `nodeIntegration` .

Done

- Remove node-ipc in favour of websockets. 
- Move file copying out of `preload.js` to avoid importing module `fs`
there
- Bump all electron pacakge versions to the latest
- Added new package for finding open ports as node-ipc is gone
- Tweaked webpack config for above changes


Partially fixes #468

Questions/ Pending:
- Literally every single test fails for me, presumably some issue with
my setup/environment.
- The websocket communication is not using TLS. I'm not sure how to
enable this, or if we even need to as its all local.
- Still need to create the CI for building/deploying but I'm not sure
where start in this regard as i have no exp with it. Presumably we will
need to point the electron auto-updater to the github releases url's. If
people are happy with this PR I will look at adding the CI before its
merged.
- In dev mode only, I have disabled TLS security becuase my docker
container's cert is not signed. I _assume_ this will be true for other
people who spin up the server on thier own hardware. Perhaps I just need
to change my cert to one from letsencrypt or something...

Notes.
I have not touched javascript in eons so my apologies if the commit
trail is a bit fragmented. I tried to keep them fairly contained and
then there is a slightly gnarly final commit fixing all the linter
issues... Please let me know if you want me to squash some commits etc.

I initially tried to move this to web workers the same way the web app
does it but this was unsuccessful. I have found no way to spin up a
worker in one place (frontend/backend) and then pass this worker to the
other. The electron ipc channels don't allow you to directly pass
objects such as workers, everything is cloned/serialised. Passing a port
number so the other end can spin up its own socket works fine.

The regex for the "space-dot" format was incorrect.

When entering the amount on a schedule, the number was incorrectly read
(12.34 became 1234.00)
Strangely, it was not an issue with transactions...

This is the last PR with lots of renaming for `loot-core`!

Another batch of `loot-core` migrated.

Fixes #913. (And probably a few other similar bugs)

Another batch of files from `loot-core` migrated to TS (loose mode)

This PR converts everything (aside from electron) from CommonJS to ESM.
It is needed to reduce the changes that will happen during the migration
to Typescript (as TS does not play nice with CJS).

Basically:
- rewrite `require()` to `import`
- rewrite `module.exports` to `exports`
- introduce `ts-node` to run importers so we can convert them to TS too

Lastly, sorry for this larg-ish PR, not my preference but when I tried
to reduce its scope, I would end up with mixed commons/esm that was even
more tricky to handle.

Part 1 of the conversion. Mostly renaming js to ts and making sure
things make still sense. Added also handy TS ESLint rules.

In order to support the various .web/.electron/... I ended up adopting
`index.d.ts` as pattern to share type definition. Let me know if that
makes sense for you too. Right now the function type definition is
duplicated, but the solution will be importing from `index.d.ts` and
using `const fn: FnDef = () => ...` that way we can keep all variants in
sync from a single type file.

Such rewrite however is better done in another PR otherwise we risk
confusing git and loosing history (rename + too many changes). Another
thing that might do in the next PR is convert all files to ESModules, as
things get confusing between CJS exports, ESM default/named and TS adds
extra complains.

- When parsing an amount string, consider surrounding parentheses to
mean the amount is negative.
- Ensures all input to `parseFloat()` is sanitized.

Closes: #807 

Seems to build fine, will test later.

I'm not sure if this is something you want but it was a simple change so
I figured I might as well contribute it. This PR allows the user to
upload `.blob` files that they may have gotten from server's
`user-files/` folder. This can be useful if the user didn't export the
file but has server backups.

- Add a “hide decimal places” setting to visually hide the `.xx` from
currency values globally
- When hiding the fractional digits, slightly decrease character spacing
to allow more digits to show up

Ref: #327
