Different ways to develop dev in SystemJs / Jspm

Question

I would like to have another way to create dev v in JSPM.

I am using JSPM version 0.17, which creates a separate dev file. In my case, they look something like this:

SystemJS.config({
    paths: {
        "npm:": "lib/npm/",
        "my_project/": "dist/"
    },
    browserConfig: {
        "baseURL": "/"
    },
    packages: {
        "my_project": {
            "main": "index.js"
        }
    }
});

SystemJS.config({
    packageConfigPaths: [
        "npm:@*/*.json",
        "npm:*.json"
    ],
    map: {
        "jquery": "npm:jquery@3.0.0"
    },
    packages: {}
});

and my config.dev.js file looks something like this:

SystemJS.config({
    transpiler: "plugin-babel",
    packages: {
        "my_project": {
            "meta": {
                "*.js": {
                    "loader": "plugin-babel"
                }
            },
        }
    },
    map: {
        "plugin-babel": "npm:systemjs-plugin-babel@0.0.12"
    }
});

What I want to do is change the path my_project from dist / to src / when the config.dev.js file is included. The idea is that the files in dist are transferred, but src are my source files.

If I enable config.dev.js then it should download files from src / and run the babel plugin. If I do not enable config.dev.js, then it should load with dist / and not start the transpiler.

, paths dev, . , config.dev.js:

paths: {
    "my_projects/": "src/"
}

, 404 mydomain/src ( - ).
