ReasonML example app repos - most don't work

vonwao · 2018-07-11 00:52:55 UTC

I wonder why ResasonML apps published on github mostly don’t work (many of them say run “npm install” and “npm start” but all I see is an empty page).

I’m sure there are multiple REasons why. Some of them I throw a compile error, some of them seem to be building fine but still not working. I’m happy to share a more detailed report of the various projects I’ve tried and symptoms.

It’s a bit discouraging as a newbie when you want to see something running and hack on it, and it’s already not working from the getgo. Is there anything the Reason community could do to improve the likelihood that example projects will be in a working state (or perhaps troubleshooting guide, etc.) and give newbies a better experience?

You may need to update the devDependencies. Most of the time for me it’s bs-platform not being the same version as my global installed version

Ok thanks, I’m not sure what is the recommended way to update devDependencies, but I did yarn upgrade and it seemed to work. Then I got a weird error about bs-platform was not installed (I thought I had it?) . I installed it again. Then I got further and finally got stuck again with this error:

Error: syntactic function type is not allowed when working with abstract bs.deriving, create a named type as work around
[8/14] Building src/ReasonReact.mliast.d[9/14] Building src/ReasonReactOptimizedCreateClass.mlast.d[10/14] Building src/ReactDOMServerRe.mlast.d[11/14] Building src/ReactEventRe.mlast.d[12/14] Building src/ReasonReact.mlast.d[13/14] Building src/ReactEventRe.mliast.d
ninja: error: rebuilding 'build.ninja': subcommand failed

That doesn’t seem to give me any line of project code that I can investigate (I’m currently looking at 2048-reasons).

By reading the error message, it seems you have an old bs-platform.
"Error: syntactic function type is not allowed when working with abstract bs.deriving, create a named type as work around"
This restriction is lifted in newer version of bs-platform

vonwao · 2018-07-12 17:36:47 UTC

Understood, but like I said above, I did yarn upgrade and installed bs-platform (via reason-cli@3.2.0-darwin, hopefully this would install latest version?).

In any case, I think we need more robust handling of different platforms and the upgrade process. There should be a simple set of steps to upgrade a project that one can take to get a project in a working state (unless code changes are required, in which case the error messages should be a little more helpful!)

I looks like I have this version:
bsc -v
The OCaml compiler, version BuckleScript 2.2.2 (Using OCaml4.02.3+BS )
Standard library directory: /usr/local/lib/node_modules/bs-platform/lib/ocaml

This looks like it’s old. I can’t find documentation on how to upgrade bs-platform, how do I upgrade?

vonwao · 2018-07-12 17:39:34 UTC

Also, I wonder why not include “you may need a newer version of bs-platform” in error messages like above. Or better yet, include a link to how to upgrade bs-platform!

drejohnson · 2018-07-12 20:17:16 UTC

You can simply update bs-platform via npm e.g. npm i -g bs-platform

vonwao · 2018-07-13 00:15:50 UTC

Thanks. Ok, I ran the this npm command. First it said “Please try running this command again as root/Administrator.” So I did sudo npm i -g bs-platform but I I still got errors. This is the debug log output:

It’s an permission error. See this https://docs.npmjs.com/getting-started/fixing-npm-permissions

Thanks. I was able to upgrade bs-platform in the meantime, using yarn instead of npm. This might be another recommended solution if you’re having problems with npm.
