How do I prevent parcel changing script variable names (without --no-minify)?

❔ Question

How do I prevent parcel changing script variable names without --no-minify?

🔦 Context

I'm creating a Doubleclick banner with parcel. Doubleclick banners require a global variable called clickTag. Parcel is changing the name of this variable. Using --no-minify works, but my js/css files are then unminified.

💻 Code Sample

.htmlnanorc
{ "collapseAttributeWhitespace": false, "collapseBooleanAttributes": false, "collapseWhitespace": "conservative", "custom": [], "deduplicateAttributeValues": false, "mergeScripts": false, "mergeStyles": false, "removeUnusedCss": false, "minifyJs": false, "minifySvg": false, "removeEmptyAttributes": false, "removeRedundantAttributes": false, "removeComments": false }

index.html:
`
<script>
var clickTag = "http://www.google.com";
</script>

`

after build
`
<script>
var o = "http://www.google.com";
</script>

`

window.clickTag would work

Great answer, Although the HTML5 Validator (https://h5validator.appspot.com/) still gives my ZIP a CLICK_TAG_MISSING. I'm going to close this because I think the real issue is with the validator -- it is only looking for var clickTag, even though the banner ad works fine.

2024 and the same issue. Has there been a solution for this year?
