# Publishing a NPM modules that depends on react-dsfr

You want to publish your own library of components that depends on react-dsfr?

Here is an example:

{% embed url="<https://github.com/EIG6-Geocommuns/geocommuns-core>" %}
A module that depend on react-dsfr and MUI
{% endembed %}

I recommend starting from ts-ci for any project meant to be published on NPM

{% embed url="<https://github.com/garronej/ts-ci>" %}

The main takeway:

* [@codegouv/react-dsfr must be a peer dependency of your project](https://github.com/EIG6-Geocommuns/geocommuns-core/blob/55e015a453a681a12bfa84624ccfd243ce8a6150/package.json#L48). Any app that would use your library would need to explicitely install react-dsfr. [For devloppement purpose, you want to add @codegouvfr/react-dsfr as devDependencies of your project](https://github.com/EIG6-Geocommuns/geocommuns-core/blob/55e015a453a681a12bfa84624ccfd243ce8a6150/package.json#L56).
* Do not add `"postinstall": "copy-dsfr-to-public"` in your library's package.json. It's the responsability of the host app to do so.
* If you rely on MUI, `@mui/material` `@emotion/styled` and `@emotion/react` should be peer dependencies as well. You should add those modules as devDependencies.
* If you use TSS: react-dsfr dosen't need to be a peerDependencies but @emotion/react does, you do not configure the emotion cache in your lib, that's the the responsability of the host app.

## 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://react-dsfr.codegouv.studio/publishing-a-npm-modules-that-depends-on-react-dsfr.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.
