Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Live Example

You can check how these library work in the next link, on live example: https://stackblitz.com/edit/ngx-translate-routes-example

Install

  npm install ngx-translate-routes --save

@ngx-translate package is a required dependency

  npm install @ngx-translate/core --save
  npm install @ngx-translate/http-loader --save

Follows this link for more information about ngx-translate: https://github.com/ngx-translate/core

Setup

Step 1: Add NgxTranslateRoutesModule to appModule, make sure you have configured ngx-translate as well

import { BrowserModule } from '@angular/platform-browser'
import { HttpClientModule, HttpClient } from '@angular/common/http'
import { TranslateModule, TranslateLoader } from '@ngx-translate/core'
import { TranslateHttpLoader } from '@ngx-translate/http-loader'

import { NgxTranslateRoutesModule } from 'ngx-translate-routes'

// part of configuration ngx translate loader function
export function HttpLoaderFactory(http: HttpClient) {
  return new TranslateHttpLoader(http) // make sure your assets files are in default assets/i18n/*
}

@NgModule({
  declarations: [AppComponent],
  imports: [
    BrowserModule,
    HttpClientModule, // required module for ngx-translate
    // required ngx-translate module
    TranslateModule.forRoot({
      defaultLanguage: 'en',
      useDefaultLang: true,
      loader: {
        provide: TranslateLoader,
        useFactory: HttpLoaderFactory,
        deps: [HttpClient],
      },
    }),
    NgxTranslateRoutesModule.forRoot(), //NgxTranslateRoutesModule added
  ],
  providers: [],
  bootstrap: [AppComponent],
})
class MainModule {}

In app module when import the module can configure if we don want to to translate routes or title for default the service will translate both features. We can pass to forRoot the following object if dont want to translate titles.

NgxTranslateRoutesModule.forRoot({
  enableTitleTranslate: false,
})

Default configuration

By default the configuration object is:

{
  enableRouteTranslate: true,
  enableTitleTranslate:  true,
  routePrefix: 'routes',
  titlePrefix: 'titles',
  enableQueryParamsTranslate: false,
  routeSuffixesWithQueryParams: {
    route: 'root',
    params: 'params',
  }
}

NgxTranslateRoutesConfig interface

export interface NgxTranslateRoutesConfig {
  enableTitleTranslate?: boolean
  enableRouteTranslate?: boolean
  enableQueryParamsTranslate?: boolean
  routePrefix?: string
  routeSuffixesWithQueryParams?: RouteSuffixesWithQueryParams
  routesUsingStrategy?: string[]
  titlePrefix?: string
  onLanguageChange?: () => void
  routeTranslationStrategy?: (originalRoute: string) => string
}

Step 2: Add error message configuration in JSON file. Ngx-translate and others internationalizations packages manage json files for each idiom thant manage. For example is your application manage english langague you must create in assets/i18n/en.jsone all the titles and routes you need to translate in your application. Every property in the json will be named as we want to discribe route, by example:

  // assets/i18n/en.json
  {
    "titles": {
        "about": "About Us",
        "users": {
            "root": "Users",
            "profile": "User Profile",
            "myaccount": "List Users"
        }
    },
    "routes": {
        "about": "aboutUs",
        "myaccount": "myAccount"
    }
  }

Use

After configuration you can use the service customizing your routes object as follow example

// app.routing.modules.ts
const routes: Routes = [
  { path: 'about', component: AboutComponent, data: { title: 'about' } },
  {
    path: 'profile',
    component: MyprofileComponent,
    data: { title: 'profile' },
  },
  {
    path: 'myaccount',
    component: MyaccountComponent,
    data: { title: 'myaccount' },
  },
  { path: 'dashboard', component: DashboardComponent, title: 'Dashboard' },
]

For translate titles we need to add in data object title value respecting the tree we create for translate titles for example title: 'about', will be replace with about value inside json translation file, follow the json in step 2 of cofiguration it title will replace with About Us. If we dont add translate for some title we will follow Dashboard example only add title attribute with the final value.

For translate routes is litle easy we only need to create the route object inside translation follow the json in step 2 of configuration. The route key in translate file must be the same as path string.

Dynamic Title

If you have a dynamic route similar to the following:

// someRouteFile-routing.module.ts
{
  path: 'profile/:userId',
  component: ProfileComponent,
  data: {
    title: 'users.profile',
  }
}

In the translation file you should respect the same name as the dynamic variable of the routes and the service will generate the translation of the dynamic title by replacing this variable with the corresponding value.

// assets/i18n/en.json
{
  "titles": {
    "users": {
      "profile": "User Profile {{userId}}",
    }
  },
  // others translations
}

Query params translation

Skip this configuration if you only wish to translate the path of the route with query parameters without translating the parameters themselves.

// app.modules.ts

@NgModule({
  imports: [
    //  Others configurations
    NgxTranslateRoutesModule.forRoot({
      enableQueryParamsTranslate: true,
      // Optional setting
      routeSuffixesWithQueryParams: {
        route: 'customRoot',
        params: 'customParams',
      },
    }),
  ],
})
export class AppModule {}
  // assets/i18n/en.json
  {
    "routes": {
      //  translations
      "example": {
        "customRoot": "example",
        "customParams": {
          "param1": "paramOne"
        }
      }
    }
  }

In this example, the library will now perform translations for the query parameters. If you want to skip the query parameter translations, the library will by default translate the path alone while keeping the original name of the query parameters. This allows users to organize their translation keys according to their own preferences or existing structures.

Customizing Route & Title paths

// app.modules.ts

@NgModule({
  imports: [
    //  Others configurations
    NgxTranslateRoutesModule.forRoot({
      routePrefix: 'customRoutes',
      titlePrefix: 'customTitles',
    }),
  ],
})
export class AppModule {}
  // assets/i18n/en.json
  {
    "customTitles": {
      // translations
    },
    "customRoutes": {
      //  translations
    }
  }

In this example, the library will now use customRoutes as the prefix for route translations and customTitles as the prefix for title translations. This allows users to organize their translation keys according to their own preferences or existing structures.

Customizing route translation strategy

@NgModule({
  imports: [
    NgxTranslateRoutesModule.forRoot({
      routeTranslationStrategy: (path: string) => `new-${path}`,
      routesUsingStrategy: ['products'],
    }),
  ],
})
export class AppModule {}

In this example, only the products routes will use the routeTranslationStrategy. For other routes, the default translation will be used.

Customizing language change events

@NgModule({
  imports: [
    NgxTranslateRoutesModule.forRoot({
      onLanguageChange: () => {
        console.log(
          'The application language has changed. Perform additional actions here.',
        )
        // For example, you could reload translated data or notify components.
      },
    }),
  ],
})
export class AppModule {}

With this in mind, you can provide your own function to handle events when the language changes in your application. This allows them to execute custom actions in response to the language change, such as updating data, notifying components, reloading the page, etc.
