chore(deps): update dependency memfs to v4 by renovate[bot] · Pull Request #1276 · finos/architecture-as-code

memfs added adapters for File System Access (FAS) API, which is a file system API available in browsers. FSA can write to a real user folder, which user picks; or without any permissions can write to a virtual file system, called OPFS (Origin Private File System). memfs implements adapters, which:

Construct a Node's fs-like API out of the FSA API.
- In browser, support for synchronous fs methods is also available using a WebWorker.
Also, the other way around, memfs can provide FSA API on top of any fs-like file system.

Other notable changes

In-memory fs changes
- A number of in-memory fs bugs were fixed.
- Type interfaces of methods and options objects for in-memory fs were improved.
- mkdirp and mkdripSync were removed, they were deprecated before. (You can pass the "recursive" flag to mkdir and mkdirSync, instead.)
- Many re-usable Node.js fs utilities now live in the /src/node folder.
- Promises API methods are now bound by default to their this object, just like in native fs module.
crudfs and casfs
- crudfs implementation on top of Node fs was added.
- crudfs implementation on top of File System Access API was added.
- casfs implementation on top of crudfs was added.
print utility was added which allows to recursively print a directory tree to terminal.
snapshot utility was added which allows to create recursive binary snapshots of folders and then load them back into some folder.
The /demo folder now contains multiple Webpack demos.
Build changes and deprecations
- TypeScript was upgraded from version 4 to 5.
- tslib is now included as peer dependency, instead of TypeScript helpers being emitted into distributable.
- TypeScript build target of the distributable is no es2017, instead of previously es5.
- The library is now tested on Node v18+ versions.
- BigInt shim is no longer shipped, memfs will rely on the BigInt provided by the JavaScript environment. You can shim that global, if necessary.
- fs-monkey dependency was removed.
New features in this major release are marked as experimental, which means those APIs are in preview, their public interface may have breaking changes even across minor releases.
CircleCI was removed, now GitHub Actions power all builds and releases.
The next branch was tested, which deploys pre-releases.
