systemjs: mapping everything else to node_modules - systemjs

Question

I am having trouble getting systemjs to work so it resolves node modules.
I have the following in my index.html:
<script src="./system.config.js"></script>
<script>
System.import('blast/test')
.then(null, console.error.bind(console));
</script>
This is my configuration:
System.config({
baseUrl: '/',
packages: {
'app': {
defaultExtension: 'js',
}
},
packageConfigPaths: ['./node_modules/*/package.json'],
paths: {
'blast/*': 'app/*'
}
});
This works fine so far. However, I want to be able to also resolve node modules like lodash. So I set paths to this:
paths: {
'blast/*': 'app/*'
'*': './node_modules/*'
}
Now I can import lodash fine, but when importing blast/test I get the error /app/test 404 (not found). It seems, the package configuration isn't used anymore, this .js isn't appended. Anyone got any hints how to resolve this? I am using SystemJs 0.19.25 Standard.
Thanks, Robin

Try using map configuration here rather for your local package -
System.config({
map: {
blast: './app'
}
});
The ./ is necessary to distinguish the URL space from becoming the node_modules/app path (probably the reason you used paths here to begin with?)
It's also advisable to use baseURL: 'node_modules' instead of a wildcard paths entry (and they pretty much amount to the same thing).
