parcel build does not minify typescript code

[nsainaney]

🐛 bug report

We are running v1.12.4 with the following command:

parcel build --no-content-hash ./src/config.ts ./src/index.html --out-dir ./lib

In several of our projects and the resulting js files in the lib folder have source maps and are not minified

🎛 Configuration (.babelrc, package.json, cli command)

The tsconfig is as follows:

{
    "compilerOptions": {
        "composite": false,
        "module": "commonjs",
        "moduleResolution": "node",
        "declaration": true,
        "noImplicitAny": false,
        "removeComments": true,
        "noLib": false,
        "outDir": "./lib",
        "rootDir": "./src",
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "esModuleInterop": true,
        "skipLibCheck": true,
        "target": "es2018",
        "sourceMap": true,
        "lib": ["es2018", "dom"],
    },
    "references": [
        { "path":  "../../common" },
        { "path":  "../../ui/packages/web" },
        { "path":  "../common" }
    ],
    "exclude": [
        "node_modules",
        "test"
    ]
}

🤔 Expected Behavior

Files should be minified and there shouldn't be any source maps
