Missing JSON Output in Build After Migrating to Parcel V2

[avoguga]

Hi there!

I've been using an application developed with Parcel v1 which has been generating some JSONs during its build process. However, after upgrading to Parcel v2, these JSONs are no longer being built.

To give you a picture of it, here are some part of my package.json files before and after migration:

Before migration:

{
    "type": "module",
    "main": "src/index.js",
    "scripts": {
        "start": "npm-run-all --parallel dev:dependencies dev:web",
        "dev:htweb": "parcel serve ../src/index.html --open --no-cache",
        "dev:dependencies": "parcel serve ./src/iframe.ts -o iframe.min.js --port 1235 --no-cache"
    },
    "alias": {
        "react": "preact/compat"
    },
    "engines": {
        "node": "^8.0.0"
    }
}

After migration:

{
  "browserslist": "> 0.5%, last 2 versions, not dead",
  "type": "module",
  "myApp": "dist/myApp.min.js",
  "iframe": "dist/iframe-app.js",
  "targets": {
    "myApp": {
      "engines": {
        "browsers": "Chrome 80"
      }
    },
    "iframe": {
      "engines": {
        "browsers": "Chrome 80"
      }
    }
  },
  "scripts": {
    "start": "npm-run-all --parallel dev:dependencies dev:web",
    "dev:ht-test": "parcel serve ./index.html --open --no-cache",
    "dev:dependencies": "parcel serve ./src/IframeApp.ts --target iframe --port 1235 --no-cache"
  },
  "alias": {
    "react": "preact/compat"
  },
  "engines": {
    "node": "^18.0.0"
  }
}

Here is a snippet of my code that was responsible for fetching the JSONs in Parcel v1:

let storageUrl = "http://localhost:1235/";

export const jsonUrl = `${storageUrl}jsons/`;

export const getJsonUrl = (file: string) => {
  return jsonUrl + file + ".json";
};

const asyncFunc = async ( ) => {
for (const file of files) {
  const url = getJsonUrl(file);
  const response = await fetch(url);

  if (response.status != 200) throw errorDownloadingJsons;

  try {
    const json = await response.json();
    jsons = { ...jsons, ...json };
  } catch {
    throw errorDownloadingJsons;
  }
}

}

Could you guys help me understand why this might be happening and suggest any possible solutions to this issue?

I don't know how this worked in Parcel 1 without any plugins (did you have any?)
