# Securing TiddlyWiki on Node.js
This guide covers using Pomerium to add authentication and authorization to an instance of [TiddlyWiki on NodeJS](https://tiddlywiki.com/static/TiddlyWiki%2520on%2520Node.js.html).
## What is TiddlyWiki on Node.js
TiddlyWiki is a personal wiki and a non-linear notebook for organizing and sharing complex information. It is available in two forms:
- a single HTML page
- [a Node.js application](https://www.npmjs.com/package/tiddlywiki)
We are using the Node.js application in this guide.
## Where Pomerium fits
TiddlyWiki allows a simple form of authentication by using authenticated-user-header parameter of [listen command](https://tiddlywiki.com/static/ListenCommand.html). Pomerium provides the ability to login with well-known [identity providers](../docs/identity-providers/readme.md#identity-provider-configuration).
## Pre-requisites
This guide assumes you have already completed one of the [quick start] guides, and have a working instance of Pomerium up and running. For purpose of this guide, We will use docker-compose, though any other deployment method would work equally well.
## Configure
### Pomerium Config
```yaml
jwt_claims_headers: email
policy:
- from: https://wiki.example.local
to: http://tiddlywiki:8080
policy:
- allow:
or:
- email:
is: reader1@example.com
- email:
is: writer1@example.com
```
### Docker-compose
<<< @/examples/tiddlywiki/docker-compose.yaml
### That's it
Navigate to your TiddlyWiki instance (e.g. `https://wiki.example.local`) and log in:
* as reader1@example.com: user can read the wiki, but there is no create new tiddler button is show up.
* as writer1@example.com: user can read the wiki and create new tiddlers.
* as another email: pomerium displays a permission denied error.
