But I don't know how to manage this kind of thing in JavaScript? I'm a little late to the thread, but if you're using Grunt I've had great success with grunt-ng-constant.

So running grunt server will generate a config. One cool solution might be separating all environment-specific values into some separate angular module, that all other modules depend on:.

The module, that contains the configuration can be separated into configuration. But it's easier to not check in the configuration if it is in a separate file. Also, you could branch it locally. For Gulp users, gulp-ng-constant is also useful combined with gulp-concatevent-stream and yargs.

Then you can run gulp config --env development and that will create something like this:. You could use lvh. And then inject the Configuration service and use Configuration. A tad clunky, but works fine for me, albeit in a slightly different situation API endpoints differ in production and development. One solution could be to continue using your config. Very late to the thread, but a technique I've used, pre-Angular, is to take advantage of JSON and the flexibility of JS to dynamically reference collection keys, and use inalienable facts of the environment host server name, current browser language, etc.

This provides not merely deploy-environment context per OP but any arbitrary context such as language to provide i18n or any other variance required simultaneously, and ideally within a single configuration manifest, without duplication, and readably obvious.

SO, if a visiting user to the production website has German de language preference setting, the above configuration would collapse to:. In our implementations, which include Angular and pre-Angular websites, we simply bootstrap the configuration well ahead of other resource calls by placing the JSON within a self-executing JS closure, including the prefer function, and fed basic properties of hostname and language-code and accepts any additional arbitrary suffixes you might need :.

A pre-Angular site would now have a collapsed no suffixed keys window. We've evolved usage of this technique to allow multiple suffixes to a key, to avoid being forced to use collections you still can, as deeply as you wantand as well to honor the order of the preferred suffixes.

Example also see working jsFiddle :. It accomplishes this by scoring each suffixed property and promoting the value of a suffixed property to the non-suffixed property when iterating over the properties and finding a higher-scored suffix. Some efficiencies in this version, including removing dependence on JSON to deep-copy, and only recursing into objects that survive the scoring round at their depth:.

NET Core application settings can be used to configure an Angular application.

NET Core provides excellent support for different configuration per environment, and so using this for an Angular application can be very useful.

Using CI, one release build can be automatically created with different configurations, instead of different release builds per deployment target.

The ClientAppSettings class is used to load the strongly typed appsettings. These properties have different values per deployment, so we do not want to add these in a typescript file, or change with each build. The appsettings. A MVC Controller is used to make the settings public. The Angular application needs to read the settings and use these in the client application.

A configClient function is used to GET the data from the server. In the constructor of the AppModule, the module subscribes to the configClient function. Here the configuration values are read and the properties are set as required for the SPA application. I am certain, there is a better way to do the Angular configuration, but not much information exists for this.

Full of security holes. A hackers dream.

All the properties are public knowlegde, which ones are dangerous? Client side settings should NOT be sensitive information anyway…. If you think your settings are secure in a client app config file, you are doing it wrong. Why people used to criticize without making any proposal? You are commenting using your WordPress.

The crucial downside of this approach is that the config is part of the application code. The application's config is considered everything that is likely to vary between deploys staging, production, etc.

How to configure your AngularJS application using environment variables

These drawbacks painfully confirm the The Twelve-Factor App config rule that states that there should always be a strict separation of config from code. They typically solve it by storing configuration details in environment variables. Then they read these environment variables from within their back-end applications. Problem solved! We already learned that back-end engineers use environment variables, so let's learn from their prior art and tackle the problem in a similar way.

Now we can use AngularJS dependency injection to inject the environment variables in a config block to configure logging:. Thanks to AngularJS dependency injection we can now access the environment variables anywhere in our AngularJS application.

No, the default env. The deployment team can then overwrite the env. Configuring the application using env. By strictly separating all configuration details in env.

As a result, this article explains how you can configure an Angular 6 application without rebuilding it. Let's get started by having a look at why the built-in Angular CLI application environments are awesome, but won't work for the purpose of configuring an application without a rebuild.

Angular CLI offers application environments to configure different settings at build time. In Angular 6, the angular. Having a build-time configuration requires that you generate a different build for each of your environments. You can automate builds and deployments, but what if your build is client-specific?

What if you wish to deploy the same Angular application for different clients with different settings? Suppose that your application is deployed using 20 different configurations, each for a different client. If the configuration changes for a client, a single rebuild is required.

However, if the application code changes, 20 rebuilds are required. An application's config is considered everything that is likely to vary between different deploys staging, production, client A, client B, etc.

Storing the application config part in your application code repository can introduce security risks. Imagine that you hire an external consultant to work on your private application code.

The consultant now has access to all private configuration data that is stored in your config, because your environments are stored in your code repository. Modern cloud-based hosting infrastructure can scale dynamically. A fixed config prevents deployments tools from dynamically scaling and configuring your application as needed. These limitations are described in more detail in The Twelve-Factor App config rule that states that there should always be a strict separation of config from code.

If your application is not affected by these limitations, the built-in Angular CLI application environments are perfect for storing configuration details.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

The target for the compilation is es5 and that is because most browsers can only understand ES5 typescript.

The sourceMap option is used to generate Map files, which are useful when debugging. Hence, during development it is good to keep this option as true. If not in place, Angular JS application will not compile. This file contains information about Angular 2 project. Following are the typical settings in the file. There are two types of dependencies, first is the dependencies and then there are dev dependencies.

What is compile-time configuration? It basically means that you compile your configuration into your app, at the time when you compile and bundle it. Inside the environments folder you have a environment. Since these are just plain JavaScript objects, you can add your environment specific properties on them.

The default main.

You can arbitrarily get a reference to that environment object by simply importing environment. The reason is that at compile time, the Angular CLI will take care of renaming the environment specific configuration file into environment.

Just create a new environment. That happens in the scripts section of our package. Moreover it also enables the AOT compilation. What you want however, is to start your app only after your settings have been loaded and applied. A naive approach could be as follows. In your app. We first create an Angular service that handles the fetching of our remote configurationcalled app-config.

That service is then imported in the app. We now need to implement the appInitializerFn factory function which we can define directly in the app. The important thing here - which you might have missed - is that the app-config. The benefit of this approach is that when the application bootstraps, it gets our initializer function, and since we return a PromiseAngular will first resolve that Promise before it continues with the bootstrapping.

As a result, within some other component, we can simply inject our AppConfigService and use its getConfig function to access our configuration props.

A common mistake though is to place initialization code in a modules constructor. Since AppComponent is the root component, loading the entire app, no other components will be instantiated either.

But what if I want to separate the config code per module? Normally such configuration code is global and per-app, which is why AppModule is the place to go. I created a quick Stackblitz to better demonstrate the order with which these modules and components get instantiated:.

Of course it depends on your specific use case and needs.
