Resources tool 🧰

Resources tool (Locals) y part of the NodeTskeleton template project.

NodeTskeleton is a Clean Arquitecture based template project for NodeJs using TypeScript to implement with any web server framework or even any user interface.

Resources

It is a basic internationalization tool that will allow you to manage and administer the local messages of your application, even with enriched messages, for example:

Using Resources

The first thing to note is that your resource files must be in json or js format as shown in an example below:

// ./locals/resources/en.local.json
// Resource file for english.
{
  "SOMETHING_WENT_WRONG": "Oh sorry, something went wrong with current action!",
	"SOME_PARAMETERS_ARE_MISSING": "Some parameters are missing: {{missingParams}}.",
	"YOUR_OWN_NEED": "You are the user {{name}}, your last name is {{lastName}} and you are {{age}} years old."
}
// ./locals/resources/es.local.json
// Resource file for spanish.
{
  "SOMETHING_WENT_WRONG": "Oh lo sentimos, algo salió mal con esta acción!",
	"SOME_PARAMETERS_ARE_MISSING": "Faltan algunos parámetros: {{missingParams}}.",
	"YOUR_OWN_NEED": "Usted es {{name}}, su apellido es {{lastName}} y su edad es {{age}} años."
}
/* others as you needed */

Important note

The parameters to be replaced in the messages should be in brackets like this, {{paramName}}.

As a second step you must have the file that corresponds to the mapping of the keys containing your resource files as shown below:

// ./locals/resources/keys.json
{
  "SOMETHING_WENT_WRONG": "SOMETHING_WENT_WRONG",
	"SOME_PARAMETERS_ARE_MISSING": "SOME_PARAMETERS_ARE_MISSING",
	"YOUR_OWN_NEED": "YOUR_OWN_NEED"
}

So now we can set up our index file which we will use to manage our internationalization resources:

// ./locals/index.ts
import { Resources } from "resources-tsk";
import * as esLocal from "./resources/es.local.json";
import * as enLocal from "./resources/en.local.json";
/* others as you needed */

import * as localKeys from "./resources/keys.json";

const locals = {
  es: esLocal,
	en: enLocal,
	/* others as you needed */
};

const defaultLanguage = "en";

const resourceKeys = localKeys;

const resources = new Resources(locals, localKeys, defaultLanguage);

/*
This line is recommended so that intellisence can suggest existing keys, however the keys will also be available from the same resources object through the resourceKeys member (resources.resourceKeys.KEY_NAME). 
*/
export { resourceKeys };

export default resources

Okay, so now you can use your resources where you need them, an example would be this:

import resources, { resourceKeys } from "../locals/index";

const simpleMessage = resources.Get(resourceKeys.ITEM_PRODUCT_DOES_NOT_EXIST);

const enrichedMessage = resources.GetWithParams(resourceKeys.SOME_PARAMETERS_ARE_MISSING, {
	missingParams: keysNotFound.join(", "),
});

// You can add enriched messages according to your own needs, for example:
const yourEnrichedMessage = resources.GetWithParams(resourceKeys.YOUR_OWN_NEED, {
	name: firstName, lastName, age: userAge
});
/*
	Output:
	You are the user Jhon, your last name is Doe and you are 24 yeard old.
*/

And you can add all the parameters you need with as many messages in your application as required.

The resource files can be local files in JSON format or you can get them from an external service.

Important

Don't forget to perform the language initialization for your resource manager in the localization middleware:

import resources from "../locals/index";

// add this line into your localization function considering the web framework you're using
resources.Init(req.headers["accept-language"] || defaultLang);
