# Mystery Snap
This is a simple MetaMask Snap that returns random numbers and answers. Below are the steps for publishing a Snap to NPM for anyone to use.
## Prerequisite
Before you begin, you should familiarize yourself with the npm documentation for [Contributing packages to the registry](https://docs.npmjs.com/packages-and-modules/contributing-packages-to-the-registry).
You will also need an npm account.
## Setup
`snap.manifest.json`:
```JSON
{
"version": "1.0.0",
"proposedName": "Mystery Snap",
"description": "A simple MetaMask Snap that returns random numbers and answers.",
"repository": {
"type": "git",
"url": "https://github.com/Montoya/random-snap.git"
},
"source": {
"shasum": "05E9ZMYL2tHWlHoTF9z4vnDqbxMFw3KfeEvHyfQeMRE=",
"location": {
"npm": {
"filePath": "dist/bundle.js",
"iconPath": "images/icon.svg",
"packageName": "mystery-snap",
"registry": "https://registry.npmjs.org/"
}
}
},
"initialPermissions": {
"snap_confirm": {}
},
"manifestVersion": "0.1"
}
```
`source` contains what will be published to NPM for distributing the Snap. Proposed package name is `mystery-snap` (this is the only field that needs to be modified from `template-snap`). Also, the icon at `images/icon.svg` should be changed to something unique.
`package.json` (partial):
```JSON
{
"name": "mystery-snap",
"version": "1.0.0",
"description": "A simple MetaMask Snap that returns random numbers and answers.",
"repository": {
"type": "git",
"url": "https://github.com/Montoya/random-snap.git"
},
```
*Make sure that the version numbers in `snap.manifest.json` and `package.json` match.*
## Publishing
Once your Snap is ready for release, use the following command to publish:
`npm publish`
*If you are running this for the first time, you may have to log in via the command line, then run this command again.*
You should see output like this:
```Bash
% npm publish

Publishing to https://registry.npmjs.org/
+ [email protected]
```
After publishing, you can visit your npm account dashboard and see your newly published Snap package:
Then, any dApp can use the published Snap ID to connect to this Snap:
```JavaScript
const snapId = `npm:mystery-snap`;
```
MetaMask will automatically fetch the Snap from the npm registry.
This repository includes a simple dApp website that uses the Snap published to npm. You can try it here: [https://montoya.github.io/random-snap](https://montoya.github.io/random-snap).
