Separate compiler and runtime packages?

1

First, thanks for creating such a great language.

I notice that including the rescript node module as a dependency causes it to build an entire compiler, with native executables, under node_modules/rescript. It also creates runtime dependencies under node_modules/rescript/lib.

That works fine for development.

However, I am using Google Cloud Functions, and I do not want the build server to download and build the entire native rescript compiler (I’m not even sure what it would do). But I do need to tell it about the runtime dependencies.

What I’ve been doing is using webpack so there are no runtime dependencies. This works fine, and I haven’t run into any problems. But I wonder for tidiness sake if it might make sense to separate the compiler, which could be included under "devDependencies", from the runtime library, which could be included under "dependencies"?

It sounds like you are lookging for External Stdlib | ReScript Language Manual

That’s a great suggestion! I’ll give that a try.

Yes, that works perfectly, thank you.

I did run into one problem, but I solved it.

My code depends on rescript-promise. The archive for rescript-promise includes a .res file but no .bs.js files. Thus, on the server, there is an error running this line in the generated js:

var $$Promise = require("@ryyppy/rescript-promise/lib/js/src/Promise.bs.js");

As a solution, I put a node_modules directory under lib and put @ryyppy/rescript-promise/lib/js/src/Promise.bs.js there, so it could be found.

@ellbur I guess you should be building your dependencies by running,

rescript build -with-deps

You can add this command in your package.json.
