# Installation

Our [NPM package](https://www.npmjs.com/package/echo3d) contains helpful components designed to work with the echo3D platform API.

## Installing the package

* Install via `npm i echo3d`:
* Importing `<model-viewer/>`:

If your framework **does not utilize server-side rendering**:&#x20;

Run `npm i @google/model-viewer` and add `import '@google/model-viewer'` to any files that utilize `<Echo/>`

If your framework **does utilize server-side rendering**:

[Issues arise](https://github.com/google/model-viewer/issues/690) when components or pages importing `model-viewer` are rendered server-side. To most reliably resolve this issue for SSR apps, provide  `model-viewer` via a script element in your `_document` file eg: `<script type="module" src="https://unpkg.com/@google/model-viewer/dist/model-viewer.min.js"></script>`

For **TypeScript apps**:

If you do not have a `globals.d.ts` file, create one within your app `src` folder, add the line `declare module 'echo3d';` and save the file to resolve compiler typing errors.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.echo3d.com/web/installation.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
