### Prerequisites
- Node.js v16
- We only need v16 because it includes [`require('crypto').webcrypto.subtle`](https://nodejs.org/docs/latest-v16.x/api/webcrypto.html#cryptosubtle) for [Matrix encryption (olm) which can't be disabled in Hydrogen](https://github.com/vector-im/hydrogen-web/issues/579) yet.

[`require('crypto').webcrypto.subtle`](https://nodejs.org/docs/latest-v16.x/api/webcrypto.html#cryptosubtle)
for [Matrix encryption (olm) which can't be disabled in
Hydrogen](https://github.com/vector-im/hydrogen-web/issues/579) yet.
- A Matrix homeserver that supports [MSC3030's](https://github.com/matrix-org/matrix-spec-proposals/pull/3030) `/timestamp_to_event` endpoint
- Currently, the only implementation is in Synapse under an experimental feature flag.
Adjust your homeserver config to enable it:
`homeserver.yaml`
```yaml
experimental_features:
msc3030_enabled: true
```
- The `/timestamp_to_event` endpoint will soon be stabilized in Synapse which means
it will be available without the feature flag. You can track progress at
https://github.com/matrix-org/synapse/issues/14390
### Get the app running
```sh
$ npm install
# Edit config/config.user-overrides.json so that `matrixServerUrl` points to your homeserver
# and has `matrixAccessToken` defined
# Edit `config/config.user-overrides.json` so that `matrixServerUrl` points to
# your homeserver and has `matrixAccessToken` defined
$ cp config/config.default.json config/config.user-overrides.json
$ npm run start-dev
$ npm run start
# To enable tracing, add the `--tracing` flag
$ npm run start-dev -- --tracing
$ npm run start -- --tracing
```
## Development
```sh
# Clone and install the `matrix-public-archive` project
$ git clone git@github.com:matrix-org/matrix-public-archive.git
$ cd matrix-public-archive
$ npm install
# Edit `config/config.user-overrides.json` so that `matrixServerUrl` points to
# your homeserver and has `matrixAccessToken` defined
$ cp config/config.default.json config/config.user-overrides.json
# This will watch for changes, rebuild bundles and restart the server
$ npm run start-dev
# To enable tracing, add the `--tracing` flag
$ npm run start-dev -- --tracing
```
If you want to make changes to the underlying Hydrogen SDK as well, you can locally link
it into this project with the following instructions:
```
# We need to use a draft branch of Hydrogen to get the custom changes needed for
# `matrix-public-archive` to run. Hopefully soon, we can get all of the custom
# changes mainlined so this isn't necessary.
