The protection engine is the same everywhere — what changes is where your code ends up and how your build pipeline is wired. Pick the guide that matches what you ship.
Protect a production React build without breaking hydration or your bundler output.
Work out which half of your Next.js app is actually public, then protect that.
Nitro keeps half your app private. The other half is a public download — protect that half.
Why an Angular production build being minified is not the same as being protected.
Your Vue bundle is minified — anyone can still read it. Close that gap.
You don’t obfuscate TypeScript — you obfuscate the JavaScript it compiles to.
Once Node.js code leaves your servers, it becomes readable. Protect what you distribute.
Every Electron app ships its source inside the package. Extract your own asar and look.
The binary embeds your frontend, but the Rust command layer is a real place to move logic.
Anything you publish to the Chrome Web Store can be unpacked and read.
The compiler makes your components disappear into clean, readable JavaScript.
“It’s a native app” is not protection when the payload is still JavaScript.
An APK is a zip file — and Hermes bytecode is a speed bump, not a wall.
Your game ships its rules to every player. Make cheating expensive.
What you can and cannot obfuscate in a plugin distributed through wordpress.org.
The one script you hand directly to the companies closest to your market.
Your product runs on the customer’s hardware, sometimes with no network at all.
Script tags, jQuery-era code, and logic written straight into your pages.
Signage players and kiosks, where four of the runtime locks fail closed.
Scoring rules and adaptive routing, in a browser the candidate administers.
Server-rendered pages still ship script, and a Blazor build ships assemblies.
A package the customer hosts on their own LMS, at a hostname you never learn.
Metering, entitlement and pricing logic, in a browser that already received the article.
Routing, quoting and screening logic, where the chain is public and the key is in the wallet.
Every term on this site defined once, from name mangling to seeded builds.
Dart, Kotlin, ClojureScript and Scala.js builds, where the compiler already renamed half of it.
Office, Teams, Figma and editor plugins: a reviewer approves it, a host runtime runs it.
Salesforce, ServiceNow and Power Apps: the vendor owns the build, and the framework calls your code by name.
A partner rebrands your code and ships it as their own: attribution matters more than reading cost.
Phased adoption for a live application: baseline first, one bundle, canary, then runtime guards.
A reader has to receive the file to render it, so the viewer and the document need different controls.
An installed app keeps the whole client on the device and runs without your server, so the decision has to be deferred rather than made locally.
Where each decision belongs when the endpoint is assumed hostile, and what protection is honestly for once authority sits on the server.
The questions that come up most often before a first protected release.
Can JavaScript ever be fully protected from copying?
No, and any vendor saying otherwise is selling something. Code a browser executes must be readable by that browser, so the honest goal is cost — turning an afternoon of reading into a week of work. Is obfuscation reversible? takes the question seriously.
Does obfuscation slow my application down?
Measurably, though rarely noticeably. Control-flow work and string lookups cost most, so keep them off per-frame and render paths. Numbers in does obfuscation slow down your app?
Will it break my build or my tests?
Not if it runs at the right point: protect bundled output last, unit-test source before it, end-to-end test the protected artifact after. See where protection belongs in your test pipeline.
Is obfuscation enough on its own?
No — it protects comprehension, not authority. Secrets and authorisation belong server-side no matter how strong the client protection: you cannot hide an API key in JavaScript.
What if my code is not shipped to a browser at all?
The same engine covers Node.js services, Electron, and software running on a customer’s own hardware.
Will a security scanner flag my protected bundle?
Sometimes — scanners treat unreadable JavaScript as a signal. It is answerable with evidence, not by removing protection: what to do when a scan flags it.
