Motivation

Features

ES2022

  • Top-level await expressions -> not available to CJS modules
    • Important, because with moduleResolution set to node16, we can only reference ESM-only modules using dynamic import syntax, which becomes much easier to write with top-level await.

ES2021

  • String.prototype.replaceAll()
  • Promise.any()

## Explanation

### TypeScript v5.0

As part of the Wallet Framework Team's OKRs (Q2 2024 O3KR4, Q3 2024 O2KR4),
we are upgrading TypeScript to v5.0+ for all packages in the core
monorepo.

These upgrades will give us access to new features, aid us in writing
more type-safe and modern code, and also allow us to reach parity with
Extension and other MetaMask projects.

### `Node16`

In order to maximize the benefits of this upgrade, we are also enabling
the `Node16` setting for the `module` and `moduleResolution` tsconfig
options.

## Motivation

### Interop: CJS modules referencing ESM modules

The core monorepo is a collection of CJS packages, which use CJS module
resolution rules internally, and are treated as CJS modules by Node.js.
This is true despite that fact that these packages are authored in
TypeScript using ESM syntax (`import`/`export` statements) and are set
up to output dual builds for both CJS and ESM.

With `Node16` or `NodeNext` enabled, CJS modules are unable to reference
ESM modules via static/synchronous `import` statements, as TypeScript
assumes them to be compiled down to CJS-only `require` statements.

There are three solutions for this issue, of which we are utilizing the
first two:
1. Update the ESM-only dependency so that it outputs a CJS build and
type declaration as well.
2. Replace the static `import` statements with dynamic import syntax
(which, based on CJS emit rules, are not transformed to `require`
statements).
3. Migrate our module to ESM (by setting `"type": "module"` in
package.json and renaming all of our scripts to *.cjs)

> See
https://www.typescriptlang.org/docs/handbook/modules/reference.html#interoperability-rules

With dependencies that we control or use extensively, we pursue the
first option, as we're doing with `superstruct` and `@metamask/utils`
(and all of the many core dependencies that are downstream of either or
both).

With dependencies that see more limited usage, we are opting for either
the second option (e.g. `multiformats`) or, if available, using a
CJS-compatible alternative (e.g. replacing `lodash-es` with `lodash`).

The third solution of migrating to ESM is the most fundamental,
long-term measure, but we are refraining from it at this stage until we
can make a concerted effort to migrate our codebase as a whole. This is
because any individual ESM migration can cause a cascading effect
through the dependency tree where other packages are now required to
migrate as well.

### Reasons for moving away from `node`/`node10`

The following outlines the motivation for switching to `Node16`, backed
by relevant entries from the official TypeScript documentation.
- Starting with TypeScript v5.0, the previously used `moduleResolution`
setting `node` is renamed to `node10`, and strongly discouraged from
usage.
- "It [reflects the CommonJS module resolution algorithm as it existed
in Node.js versions earlier than
v12](https://www.typescriptlang.org/docs/handbook/modules/reference.html#node10-formerly-known-as-node).
**It should no longer be used.**"
- "Because `node16` and `nodenext` are the only module options that
reflect the complexities of Node.js’s dual module system, they are the
[**only correct module options** for all apps and libraries that are
intended to run in Node.js v12 or
later](https://www.typescriptlang.org/docs/handbook/modules/reference.html#node16-nodenext),
whether they use ES modules or not."
- The `node10` setting is unable to guarantee correct module resolution
for ESM-only dependencies.
- "[Because Node.js v12 introduced different module resolution rules for
ES
modules,](https://www.typescriptlang.org/docs/handbook/modules/theory.html#module-resolution)
though, it’s a very bad model of modern versions of Node.js. It should
not be used for new projects."
- "`node16` and `nodenext` describe the full range of behavior for
Node.js’s dual-format module system, and **emit files in either CommonJS
or ESM format**. This is different from every other `module` option,
which are runtime-agnostic and force all output files into a single
format, [leaving it to the user to ensure the output is valid for their
runtime.](https://www.typescriptlang.org/docs/handbook/modules/reference.html#node16-nodenext)"
- The `node10` setting does not support the package.json `"exports"`
field, which is used in our libraries to expose dual builds and type
declarations.
-
https://www.typescriptlang.org/docs/handbook/modules/reference.html#packagejson-exports
- The `Node16` and `NodeNext` settings maximize downstream
compatibility.
- "When compiling a library, you don’t know where the output code will
run, but you’d like it to run in as many places as possible. Using
"module": "nodenext" (along with the implied "moduleResolution":
"nodenext") is the best bet for maximizing the compatibility of the
output JavaScript’s module specifiers, since [it will force you to
comply with Node.js’s stricter rules for import module
resolution.](https://www.typescriptlang.org/docs/handbook/modules/theory.html#module-resolution-for-libraries)"
- "`"moduleResolution": "nodenext"` is only checking that the output
works in Node.js, but in most cases, [module code that works in Node.js
will work in other runtimes and in
bundlers](https://www.typescriptlang.org/docs/handbook/modules/theory.html#module-resolution-for-libraries)"
  
#### `Node16` vs. `NodeNext`

The two settings are currently identical, and `Node16` is intended to
work with all current node versions v16 or higher. If additional
capabilities are added to `NodeNext` or `Node18`/`Node20` that we want
to apply to our codebases, we will be able to introduce them after
checking for disruptive regressions or breaking changes.

#### Relationship with other tsconfig options

- `--module` `nodenext` or `node16` implies and enforces the
`moduleResolution` with the same name (and vice versa).
- `--module` `node16` implies (up to) `--target` `es2022`.
  - `--module` `nodenext` implies (up to) `--target` `esnext`.

## Release order roadmap

Due to interdependencies between the packages involved in this PR, we
will need to update and release them in a specific order:

- [x] #4516
- [x] Release `{base,permission}-controller`
- [x] (wait for releases: `snaps-sdk`, `snaps-utils`,
`snaps-controllers`, `keyring-api`)
  - [x] MetaMask/keyring-api#356
  - [x] MetaMask/snaps#2445
  - [x] MetaMask/snaps#2584
  - [x] MetaMask/snaps#2589
- [x] Remove yarn resolutions for `snaps-sdk`, `snaps-utils`,
~`keyring-api`~
- [ ] Merge this PR: #3645
- [x] Set yarn resolution for `@metamask/providers` via
`@metamask/snaps-sdk` to `17.1.1`
- [x] Leave messages in Changelog for affected packages
(`{accounts,chain,profile-sync}-controller`) to hold off on new releases
    ```md
    ### Uncategorized

- Please hold off on new releases of this package until the yarn
resolution for `@metamask/providers` is removed.
- This is blocked by a `@metamask/snaps-sdk` release with
`@metamask/providers` bumped to `>=17.1.1`.
- See: [Fix regressions introduced by
@metamask/[email protected]](MetaMask/snaps#2579)
- Build error fixed by yarn resolution:

    ```
- [ ] Release all core pkgs (especially deps of `snaps-controllers` and
consumers of `utils`)
- Exclude core pkgs that have `snaps-controllers` as dependency, and are
affected by `@metamask/providers` yarn resolution
    - `{accounts,chain,profile-sync}-controller`
- [ ] Release `snaps-controllers`
- [ ] Release `{accounts,chain,profile-sync}-controller`,
`eth-snap-keyring`
(MetaMask/eth-snap-keyring#311)
