Debugging CoffeeScript line-by-line

Question

Is there a way to debug CoffeeScript line-by-line?

I understand that it compiles into Javascript. But this sounds like it could make it a pain to debug.

Answer 1

now is 2020, i find this question, and then i find vscode support sourcemap, so we can use vscode to debug coffee directly.

btw, i think coffee need a great improve. just like static data. anyway here is my launch.json:

{
    "version": "0.2.0",
    "configurations": [{
        "type": "node",
        "request": "launch",
        "name": "Launch Program",
        "skipFiles": [
            "/**"
        ],
        "program": "${file}", //important, make sure debug current file
        "outFiles": [
            "${workspaceFolder}/dist/api/api.js" //important, where to find sourcemap js file
        ]
    }]
}
