Why Is My Babel File Replicated Without Transformation?

Babel File Replicated Without Transformation

Your code snippet employs browserSync and http-proxy to create a proxy server. However, running babel proxy.js --out-file proxified.js yields only a copy of the original file.

Babel, a transformation framework, has undergone a change in default behavior from pre-6.x versions. Previously, specific transformations were enabled by default, but current versions require explicit configuration.

To specify transformations, you need:

• Install babel-preset-env with npm install babel-preset-env.
• Run babel --presets env proxy.js --out-file proxified.js or create a .babelrc file with the following contents:

{
    "presets": [
        "env"
    ]
}

• Then, run the command as before.

The "env" preset compiles standard ES* behavior to ES5. If your Node version supports ES6 features, consider using the following .babelrc to process only unsupported features:

{
    "presets": [
        ["env", { "targets": { "node": "true" } }]
    ]
}

You can further customize targets if required for browser support.
