Getting package to work in binder notebook (preliminary)

[djsegal]

example binder project:

• https://github.com/djsegal/webio-binder

corresponding binder:

• http://35.192.139.11/v2/gh/djsegal/webio-binder/master

---

i tried to make the simplest binder package, but couldn't get webio to work on it.

could you take a look? don't know who to ask :(

So it needs a server plugin that can serve assets from /pkg/ ... See https://github.com/JuliaGizmos/WebIO.jl/blob/master/deps/jlstaticserve.py

I guess the trick is getting it to install in binder

[djsegal]

Do you see anything obviously wrong with this file:

• https://github.com/djsegal/webio-binder/blob/master/postBuild

Or is that not related to this?

[shashi]

Looks fine as long as

/srv/julia/pkg/ is in Julia's LOAD_PATH.

I guess the thing to check is whether binder is picking up the config file that WebIO.build() injects into.

Also it might have something to do with #58

@shashi what does it mean if the yarn.js install fails:

error webpack@4.1.1: The engine "node" is incompatible with this module. Expected version ">=6.11.5".

update: It looks like webpack@4.1.1 requires nodejs@6.11.5, but binder only has nodejs@6.11.4

// Currently trying to resolve how to update nodejs

[shashi]

It seems like that webpack version needs a certain node version which does not exist on binder.

In the interest of making this work on many systems, I'm easy about which version of webpack we insist on as long as it is able to successfully build the files we need.

However I would have thought WebIO would use the node binary installed by NodeJS.jl. Is that not the case?

[djsegal]

NodeJS.jl is not REQUIREd by WebIO.jl

That will be the next thing I try out

[shashi]

Actually to install server plugin one just needs to run build.

You're trying a Dev install which is strictly not needed

[djsegal]

I'm pretty sure it says that web_comm doesn't exist then

// let me try in a couple hours

---

edit: what exactly do I need to run?

I don't call either of these things:

WebIO.devsetup() # run once
WebIO.bundlejs() # run every time you update a file
