TypeScript types for Enonic XP

[!NOTE] There now exists official TypeScript-types from Enonic. The new purpose of this library will be to provide types for all the libraries that doesn't have official support yet.

Installing individual packages

You can install individual packages with support for Enonic libraries like this:

You can find the complete list of supported packages on npm.

npm i --save-dev @item-enonic-types/global
npm i --save-dev @item-enonic-types/lib-menu

Update tsconfig.json

We recommend using starter-tsup as the base of your XP-project.

To add the TypeScript-types you need to update your tsconfig.json with the following:

{
  "compilerOptions": {
    "target": "es5",
    "strict": true,
    "sourceMap": true,
    "allowJs": true,
    "noImplicitAny": true,
    "noImplicitReturns": true,
    "noImplicitThis": true,
    "strictNullChecks": true,
    "noUnusedLocals": true,
    "noUnusedParameters": true,
    "module": "commonjs",
    "moduleResolution": "node",
    "types": ["@item-enonic-types/global"],
    "rootDirs": [
      "./src/main/resources",
      "./.xp-codegen"
    ],
    "paths": {
      "/lib/xp/*": ["./node_modules/@enonic-types/lib-*"],
      "/lib/*": [ "./node_modules/@item-enonic-types/lib-*" ,"./src/main/resources/lib/*"],
      "/site/*": ["./src/main/resources/site/*" ,"./.xp-codegen/site/*"]
    }
  },
  "include": [
    "./.xp-codegen/**/*",
    "./src/main/resources/**/*"
  ],
  "exclude": ["./build/*"]
}

Note that individual packages that are not directly under "/lib/..." needs to be mapped separately.

An example is Freemarker:

{
  "compilerOptions": {
    "paths": {
+     "/lib/tineikt/freemarker": ["./node_modules/@item-enonic-types/lib-freemarker"]
    }
  }
}

Code generation

We recommend using this library together with the xp-codegen-plugin Gradle plugin. xp-codegen-plugin will create a TypeScript type for your content-types. Those interfaces will be very useful together with this library.

Example

We have an Enonic service that returns an article by id.

import type { Article } from "../../site/content-types"; // 1
import { get as getOne, type Content } from "/lib/xp/content"; // 2

type ContentArticle = Content<Article, "my.awesome.project:Article">;

export function get(req: XP.Request): XP.Response { // 3
  const content = getOne<ContentArticle>({ 
    key: req.params.id!
  });

  assertIsDefined(content); // 4

  const article: Article = content.data;
  
  return {
    status: 200,
    body: article
  }
}

/** 
 * Create this function in a utilities file of your choice... 
 */
function assertIsDefined<T>(value: T): asserts value is NonNullable<T> {
  if (value === undefined || value === null) {
    throw new Error(`${value} is not defined`);
  }
}

1. We import an type Article = { ... } generated by xp-codegen-plugin.
2. The standard XP-libraries are mapped to their paths by the change to tsconfig.json.
3. We use XP.Request and XP.Response to control the shape of our controller.
4. content is of the type Content<Article> | null, but we can "assert" that it is not nullable (or throw an exception here if it is).
