# Run the app builder locally

## Configure 

Open the file Builder/firebase\_config.js. 

Here you should enter the firebase connection string.

Open config/app.js 

There enter your admin email, purchase code etc..

## Install the npm modules

Using Terminal or Command Prompt navigate to the downloaded and extracted zip. Then navigate to the folder "Builder" 

```
cd Builder
npm install
npm run start
```

This will start your project on localhost. You will get the correct link. Probably 

{% embed url="<http://localhost:3000>" %}

### Publish on your own hosting

After you have run the builder locally, and if it works ok you can easily publish it on your own hosting if you want.&#x20;

run

```
npm run build
```

This command will make a **dist** folder.&#x20;

Upload this **dist** folder to your hosting.&#x20;

## 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://mobidonia.gitbook.io/react-app-builder/advance-configurations/run-the-app-builder-locally.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.
