Doesn't seem to work?

[unional]

I follow the example to do:

// in an empty folder.
yarn global add systemjs-tools
yarn add systemjs systemjs-nodelibs systemjs-plugin-babel react react-dom
systemjs config

But the systemjs config just exit and no generated.config.js is created.

[unional]

I'm using yarn: 0.19.1, npm: 4.0.5, node: 7.5.0

I think the command has changed to generate-config. Run systemjs --help to verify.

[unional]

Thanks. It now complains:

:: exiting :: couldn't find a valid systemjs-tools config

[alexisvincent]

Damn. I recently changed how systemjs initializes itself. Just heading in to a meeting now. Can fix after that.

[unional]

No problem. Take your time. 🌷
Thanks for the good work.

[alexisvincent]

@unional Just had a look, I actually use the config for systemjs-tools, so to fix this, in your package.json, add:

{
    ...
    "systemjs-tools": {}
    ...
}

This will indicate to config builder where the root is. You can also customize the cache file location via

{
    ...
    "systemjs-tools": {
        "cache": ".myCustomeCacheFile.json"
    }
    ...
}

@unional did this solve your issue?

[unional]

I see. Have not try it yet.
Is it possible to make it not rely on this?
IMO it sounds like an optional configuration.
Are you doing a lookup in folder structure to find the root package.json?

[alexisvincent]

Yes, and then it uses the file it finds to act as a 'root'. But can probably offer a default. Although this isn't high priority for me right now

Could you add some documentation on how the cache works? Every time I run generate-config, it takes a long time to complete, and don't see any cache files created.

[alexisvincent]

I don't have time to write docs right now, since I'm right in the middle of exams, but you can take a look here
https://github.com/alexisvincent/systemjs-tools/blob/master/lib/cli.js#L21

It gets the cache out of the systemjs cache. You should see a .systemjs.cache.json file, which you configure by the cache key in the config. Checkout https://github.com/alexisvincent/systemjs-tools/blob/master/docs/config.md.

[simondiep]

There might be a bug with the cache generation, as I see a systemjs.cache file created but with contents of undefined.
