How do I get rid of console logs from an ionic 2 release application? I am developing an ionic 2 app. When I build the signed release apk for Android and run on a device, I can still attach to the process from `chrome://inspect`, and view console logs. **I have tried removing the cordova-plugin-console, but that makes no difference.** On a related issue, I am also able to view decoded HTTPS traffic using `chrome://inspect`. **Edit:** I found [this](https://www.npmjs.com/package/remove-console-logs) package which claims to do what I want. How can I go about including it into my ionic build process when building release version? Thanks. ---

For the most part, you shouldn’t really have to worry about this. Since production ios and android builds removed debugging capabilities, no will be able to see these/access them. ---

Hi Mike, I am currently testing with Genymotion and can see console logs and private HTTPS traffic if I attach to the release APK with chrome://inspect. I also tried creating a new project to test and can reproduce with the following steps: ```auto ionic start -v2 testblank blank ionic plugin remove cordova-plugin-console ionic build android --release --prod -- --keystore="..." --alias=... install on Genymotion and inspect with Chrome ``` ```auto $ ionic info ****************************************************** Dependency warning - for the CLI to run correctly, it is highly recommended to install/upgrade the following: Please install your Cordova CLI to version >=4.2.0 `npm install -g cordova` ****************************************************** Your system information: You have been opted out of telemetry.

As you stated production Android builds removed the debugging capabilities. However when I follow the instructions here [Ionic Publishing](https://ionicframework.com/docs/guide/publishing.html) for `cordova plugin rm cordova-plugin-console --save` (since I have it in my `config.xml`) and then make a production release using `ionic build android --release --prod` the app crashes on startup. I zip aligned and signed the production Android release properly. If I follow the same exact steps omitting `cordova plugin rm cordova-plugin-console --save` the app works as expected and the console logs are not seen. I’m not sure if this is a bug or this is a required plugin in which this should be noted someplace. Here’s my `ionic info`: ```auto ****************************************************** Your system information: Cordova CLI: 6.5.0 Ionic Framework Version: 2.0.1 Ionic CLI Version: 2.2.1 Ionic App Lib Version: 2.2.0 Ionic App Scripts Version: 1.0.1 ios-deploy version: Not installed ios-sim version: Not installed OS: macOS Sierra Node Version: v7.1.0 Xcode version: Xcode 8.2.1 Build version 8C1002 ****************************************************** ``` ---

You can use uglifyjs.config.js for drop all console logs. 1. Copy uglifyjs.config.js from node\_modules into your project folder 2. In the new config file set the flag drop\_console to true ```auto compress: { drop_console: true }, ``` 3 . Set your custom configuration in the package.json ```auto "config": { "ionic_uglifyjs": "uglifyjs.config.js" }, ``` And that’s all ! ---

Where’d you find this? Is there more? 😮 ---

I do it like this: `app/config/uglifyjs.config.js` ```auto let defaultConfig = require('@ionic/app-scripts/config/uglifyjs.config'); module.exports = Object.assign({}, defaultConfig, { compress: Object.assign({}, defaultConfig.compress, { drop_console: true, drop_debugger: true }) }); ``` `app/package.json` ```auto { ...

I tried the uglify trick, but logs are still there.I tried several different things, but I can’t get rid of logs in release apk no matter what. Did anybody managed to make it work? ---

> [@infoproducts](#): > > drop\_debugger Can I do something similar with an older Ionic v1 app? ---

For someone looking for a quick solution, just add this to src/app/main.ts ```auto import { platformBrowserDynamic } from '@angular/platform-browser-dynamic'; import { AppModule } from './app.module'; // disable console log console.log = function(){}; platformBrowserDynamic().bootstrapModule(AppModule); ``` ---

The solution suggested by @guillefd will hide the printouts to console, but performance win will be lesser then when removing calls to console.log() ---

Is this still true with Capacitor / Ionic4 ?
