How to use

This library contain its own data model, please double check the data model from server is same as error.model.ts
This library contain its own translation, which use ngx-translate. Translation json are located in assets folder.
1. after build this library make sure the assets folder also copy to the dist folder.
2. after npm publish, please make sure the main project which will import this lib, able to support multiple translate http loader. Without support multi loader, the translation for this library will not work, and it might clash to your main project translation
```
   export function HttpLoaderFactory(http: HttpClient) {
     return new MultiHttpTranslateLoader(http, [
       {prefix: "./assets/i18n/", suffix: ".json"},
       {prefix: "./lib/list-errors/assets/i18n/", suffix: ".json"},
     ]);
   }
```
3. After npm install this lib in your main project, then add below configuration into angular.json assets path.
```
"assets": [
     "src/assets",
     ......
     .....
     ...
     {
       "glob": "**/*",
       "input": "./node_modules/@next-level-integration/list-errors/assets",
       "output": "./lib/list-errors/assets/"
     }
   ],
```
4. then the translation will work as expected in the list-errors components. Above point 1, 1st prefix map is actually refer to point 2 output folder.
