BrowserFS Deprecated

[james-pre]

Hi there, I'm the maintainer of BrowserFS. I've been going through the dependents of browserfs.

Please see the notice in the readme: https://github.com/jvilk/browserfs

Would you be interested in updating your project to use the updated fork, ZenFS?

[RichDom2185]

Hi, thanks for reaching out and informing us of the notice!

It seems like ZenFS is a simple drop-in replacement, so it seems doable. We are trying to modernize our dependencies as well at the moment so it is a good chance to remove any outdated/deprecated packages.

Are you interested in making a PR for it?

[james-pre]

@RichDom2185,

While I wouldn't mind helping, I've made a lot of issues about this and making PRs for each one is not feasible. However, I'm certainly willing to help out. The ZenFS readme should have enough information to migrate from BrowserFS. If you need any additional information or have any questions, please reach out to me and I will do my best to help.

[RichDom2185]

@james-pre No worries, I just wanted to check if you perhaps have made a codemod or some equivalent thing to automate the migration process before I started, as I understand you must have made a lot of issues regarding this.

Otherwise, that's fine, I'll work on the PR, thank you!

[james-pre]

For most use cases, it should be straightforward to upgrade so I think it would be better to do the migration manually. That way the programmer can choose how to configure ZenFS.

[RichDom2185]

@james-pre it seems like @zenfs/core includes its source (TypeScript) code in the published release on NPM, which is causing type errors in our codebase when we run yarn tsc:

Not sure if this is something related to our project configuration, but perhaps could you consider only shipping the dist folder?

[james-pre]

@RichDom2185 this is because the tsconfig.json was not published as well. v0.9.6 should fix the issue.

[RichDom2185]

@james-pre Thanks for the quick response! Unfortunately, despite updating to the latest versions of @zenfs/core and @zenfs/dom, we are still facing issues (also removed node_modules and reran yarn install to be safe).

Judging by the type errors and also cross-checking your tsconfig.json, it seems like strict mode is not enabled, thus causing the issues with null and undefined values, among others.

I'm thinking of just figuring out how to disable the typechecking for node_modules but I thought you might want to take a look as well, full output of yarn tsc below:

@RichDom2185,

I feel that using strict mode would actually benefit ZenFS... I'm working on making those changes and plan on releasing them soon. I've already found and corrected a number of bugs thanks to strict mode so it is definitely helping.

[james-pre]

@RichDom2185 Strict mode has been added in core v0.9.7 and DOM v0.2.6. Also, the tsconfig is also published along with the sources. You should have more success with that. Please let me know if you have any issues.
