## Description
This PR upgrades Prettier to v2 + enforces TypeScript’s [`import
type`](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-8.html#type-only-imports-and-export)
syntax where applicable. It’s submitted as a separate PR so we can merge
it easily.
As a part of this PR, we reformat the codebase heavily:
- add `import type` everywhere where it’s required, and
- re-format the code to account for Prettier 2’s breaking changes:
https://prettier.io/blog/2020/03/21/2.0.0.html#breaking-changes
This PR is submitted against `release` to make sure all new code by team
members will adhere to new formatting standards, and we’ll have fewer
conflicts when merging `bundle-optimizations` into `release`. (I’ll
merge `release` back into `bundle-optimizations` once this PR is
merged.)
### Why is this needed?
This PR is needed because, for the Lodash optimization from
7cbb12af88,
we need to use `import type`. Otherwise, `babel-plugin-lodash` complains
that `LoDashStatic` is not a lodash function.
However, just using `import type` in the current codebase will give you
this:

That’s because Prettier 1 can’t parse `import type` at all. To parse it,
we need to upgrade to Prettier 2.
### Why enforce `import type`?
Apart from just enabling `import type` support, this PR enforces
specifying `import type` everywhere it’s needed. (Developers will get
immediate TypeScript and ESLint errors when they forget to do so.)
I’m doing this because I believe `import type` improves DX and makes
refactorings easier.
Let’s say you had a few imports like below. Can you tell which of these
imports will increase the bundle size? (Tip: it’s not all of them!)
```ts
// app/client/src/workers/Linting/utils.ts
import { Position } from "codemirror";
import { LintError as JSHintError, LintOptions } from "jshint";
import { get, isEmpty, isNumber, keys, last, set } from "lodash";
```
It’s pretty hard, right?
What about now?
```ts
// app/client/src/workers/Linting/utils.ts
import type { Position } from "codemirror";
import type { LintError as JSHintError, LintOptions } from "jshint";
import { get, isEmpty, isNumber, keys, last, set } from "lodash";
```
Now, it’s clear that only `lodash` will be bundled.
This helps developers to see which imports are problematic, but it
_also_ helps with refactorings. Now, if you want to see where
`codemirror` is bundled, you can just grep for `import \{.*\} from
"codemirror"` – and you won’t get any type-only imports.
This also helps (some) bundlers. Upon transpiling, TypeScript erases
type-only imports completely. In some environment (not ours), this makes
the bundle smaller, as the bundler doesn’t need to bundle type-only
imports anymore.

## Description
Any platform function that accepts a callback were unable to access the
variables declared in its parent scopes. This was a implementation miss
when we originally designed platform functions and again when we turned
almost every platform function into a Promise. This PR fixes this
limitation along with some other edge cases.
- Access outer scope variables inside the callback of run, postMessage,
setInterval, getGeoLocation and watchGeolocation functions.
- Fixes certain edge cases where functions with callbacks when called
inside the then block doesn't get executed. Eg `showAlert.then(() => /*
Doesn't execute */ Api1.run(() => {}))`
- Changes the implementation of all the platform function in appsmith to
maintain the execution metadata (info on from where a function was
invoked, event associated with it etc)
#### Refactor changes
- Added a new folder **_fns_** that would now hold all the platform
functions.
- Introduced a new ExecutionMetadata singleton class that is now
responsible for hold all the meta data related to the current
evaluation.
- Remove TRIGGER_COLLECTOR array where all callback based platform
functions were batched and introduced an Event Emitter based
implementation to handle batched fn calls.
- All callback based functions now emits event when invoked. These
events have handlers attached to the TriggerEmitter object. These
handler does the job of batching these invocations and telling the main
thread. It also ensures that platform fn calls that gets triggered out
the the context of a request/response cycle work.
