detect-browser | JavaScript library to detect browser properties

I'm using the latest versions of all Angular-related packages (so Angular 10).

I want to add some code to a component, but I only want this code to exist in dev, never in a production build. It needs to be completely stripped in prod builds. I found this comment, which indicates that environments do this automatically (because they're const).

I tried using that exact code in my app, but the dev code is still there in a production build. I copied the code over to a new test app that I made with ng new, and it does work properly there.

What things should I be looking for, how can I fix this? Is this possibly because I have CommonJS dependencies, and if so, can I do anything about that (since I can't remove those dependencies)?

Some notes:

• An issue has been opened on the angular-cli repo here.
• The environment object is never written to anywhere in the codebase, I've searched thoroughly. (It's only used in a few places anyway.)
• Code bounded with if (false) { } is properly stripped.
• Removing the services export from the end of environment{.prod}.ts does not fix the problem.
• Removing all CommonJS dependencies does not fix the problem.

Here's environment.prod.ts (environment.ts is the same, just with false instead of true):

After update to angular 9 and universal 9, a got error when i run npm run build:ssr && npm run serve:ssr

I using "Detect browser wrapped lines via javascript" as a way to wrap each line in a . However, I'm having a problem if there's more than one element to split and wrap.

For example: If I have more than one section to split and wraps like:

I found JS code from "Detect browser wrapped lines via javascript" but it will wrap white-spaces into a span. I'm using this code on a WordPress site and I cannot reciprocate the problem anywhere else. I tried to sanitize the code but that didn't work as well.

Is there a way to check if a span is blank and remove the span?

I have a JS code that I got from "Detect browser wrapped lines via javascript" that wraps each line into a . It works when there's one set of text to wrap inside a

You can see in my example code below, the first set of text will work (green line above the text) but the second set will not.

I am using `detect-browser' library in React component. I have as following:

I built an angular application which runs fine if I serve it in a non-production mode but if I run it with --prod I get the following error:

Uncaught TypeError: this._platformLocation.onPopState is not a function

The LocationStrategy is provided correctly and it's the latest angular version which should have this bug fixed already.

I am working on an Angular project that does not, and cannot for now, use the Angular CLI. So I am trying to setup a Karma config but I get this error:

Last week, without any changing of our configurations or dependencies, our builds started failing.

The errors we are getting during any run of any karma tests are along the lines of:

26 03 2018 10:25:34.870:INFO [framework.detect-browsers]: The following browsers were detected on your system: [ 'Chrome', 'Chromium' ] 26 03 2018 10:25:34.874:WARN [framework.detect-browsers]: No launcher found for browser Chrome, it will not be used. 26 03 2018 10:25:34.874:WARN [framework.detect-browsers]: No launcher found for browser Chromium, it will not be used. 26 03 2018 10:25:34.874:INFO [framework.detect-browsers]: The following browsers will be used: []

We can replicate this on all machines across versions 1 of karma-detect-browsers, all the way up to the latest 2.3.1.

All the machines may use potentially slightly different versions of node and npm, but our CI server where this was first detected uses node version 8.4.0 and npm version 5.3.0.

Not sure if anyone else has had this problem or can offer some advice?
