How to use ts compiler api or ts-morph to get and serialize type information

I am trying to use the Typescript API to get information from typescript file that imports types from other sources.

I got common type:

// example.types.ts

export interface Example<T> {
  description: string;
  title: string;
  element: T;
}

Then some element component or class I want to prepare example for

// Canvas.ts

interface ICanvasConfig {
  name: string;
  size: {
    width: number;
    height: number;
  };
}

export const Canvas = (config: ICanvasConfig): void => {
  console.log(config);
};

And this is the target file I want to parse

// Canvas.example.ts

import type { Example } from './example.types';

import { Canvas } from './Canvas';

const exampleMeta: Example<typeof Canvas> = {
  title: 'Canvas Element',
  description: 'Element used for..',
  element: Canvas
};

export default exampleMeta;

What I'm expecting is to get at the end something like

{
  title: {
     value: 'Canvas Element',
     type: 'string'
  }
  description: {
    value: 'Element used for..',
    type: 'string',
  },
  element: {
    value: Canvas, // real value
    type: {
      name: 'function',
      args: [{
          name: 'string',
          size: {
            width: 'number',
            height: 'number'
          }
      }],
      ret: 'void'
    }
  }
}

I tried to use ts compiler and ts-morph but all I do is beating around the bush.
I wont publish my solution attempts not to distract you, but it seems I don't understand the inner structure of ts nodes to get what I need. Maximum what I got playing around is detecting title, description as a string but any type for element.

So my question is it actually possible using these tools? If yes then how? Are there any better solutions to achieve what I need?

Or if you ever faced with similar problems sharing your experience would be much appreciated.

You can achieve that using ts-morph with the code below.
This code only works for the example code you provided, but it should be easy to implement a more generic solution using recursion.

I also found a related GitHub issue "Question: Is there a simple way to get a type reduced to only primitives?" and it has a library for expanding types https://github.com/dsherret/ts-morph/issues/1204#issuecomment-961546054, although it does not extract values such as 'Canvas Element'. To use that add type exampleMeta = typeof exampleMeta to Canvas.example.ts and run import { typeFootprint } from "./typeFootprint"; console.log(typeFootprint("src/Canvas.example.ts", "exampleMeta")); to get the string *1.

import { Project, SyntaxKind } from "ts-morph";
import util from "util"  // for displaying a deep object

const project = new Project({})

// Assuming the files `example.types.ts`, `Canvas.ts`, and `Canvas.example.ts` are in `./src`.
project.addSourceFilesAtPaths("src/**/*.ts")
const exampleMeta = project.getSourceFile("src/Canvas.example.ts")!.getVariableDeclaration("exampleMeta")!

const exampleMetaValue = exampleMeta
    // "go to definition"
    .getFirstChildByKindOrThrow(SyntaxKind.Identifier)
    .getDefinitionNodes()[0]!

    // get the initializer `{ title: ..., description: ..., ... }`
    .asKindOrThrow(SyntaxKind.VariableDeclaration)
    .getInitializerOrThrow()

// "go to type definition"
const exampleMetaType = exampleMeta
    .getType()

console.log(util.inspect({
    // You can list properties with `exampleMetaType.getProperties().map((property) => property.getName())`
    title: {
        value: exampleMetaValue
            // .title
            .asKindOrThrow(SyntaxKind.ObjectLiteralExpression)  // You can check the kind with `.isKind()` or `.getKindName()`
            .getPropertyOrThrow("title")

            // get the initializer `Create Element`
            .asKindOrThrow(SyntaxKind.PropertyAssignment)
            .getInitializerOrThrow()
            .getText(),
        type: exampleMetaType
            // .title
            .getPropertyOrThrow("title")
            .getTypeAtLocation(exampleMeta)
            .getText(),
    },
    description: {
        value: exampleMetaValue
            // .description
            .asKindOrThrow(SyntaxKind.ObjectLiteralExpression)
            .getPropertyOrThrow("description")

            // get the initializer `Element used for..`
            .asKindOrThrow(SyntaxKind.PropertyAssignment)
            .getInitializerOrThrow()
            .getText(),
        type: exampleMetaType
            // .description
            .getPropertyOrThrow("description")
            .getTypeAtLocation(exampleMeta)
            .getText(),
    },
    element: {
        value: exampleMetaValue
            // .element
            .asKindOrThrow(SyntaxKind.ObjectLiteralExpression)
            .getPropertyOrThrow("element")

            // get the initializer `Canvas`
            .asKindOrThrow(SyntaxKind.PropertyAssignment)
            .getInitializerOrThrow()

            .getText(),
        type: {
            name: exampleMetaType
                // .element
                .getPropertyOrThrow("element")
                .getTypeAtLocation(exampleMeta)
                .getCallSignatures().length > 0 ? "function" : "",
            args: exampleMetaType
                // .element
                .getPropertyOrThrow("element")
                .getTypeAtLocation(exampleMeta)
                // Parse '(config: ICanvasConfig) => void'
                .getCallSignatures()[0]!
                .getParameters().map((arg) => {
                    const iCanvasPropertyType: any = {}
                    for (const iCanvasConfigProperty of arg.getTypeAtLocation(exampleMeta).getProperties()) {
                        iCanvasPropertyType[iCanvasConfigProperty.getName()] = iCanvasConfigProperty
                            .getTypeAtLocation(exampleMeta)
                            .getText()  // TODO: Parse '{ width: number; height: number; }'
                    }
                    return iCanvasPropertyType
                }),
            ret: exampleMetaType
                // .element
                .getPropertyOrThrow("element")
                .getTypeAtLocation(exampleMeta)

                // Parse '(config: ICanvasConfig) => void'
                .getCallSignatures()[0]!
                .getReturnType()
                .getText(),   // .getFlags() & TypeFlags.Void === true
        },
    },
}, { depth: null }))

type exampleMeta = {
  description: string;
  title: string;
  element(config: {
    name: string;
    size: {
      width: number;
      height: number;
    };
  }): void;
