Gist-Reveal.it is an open source slideshow templating service that makes it easy to create, edit, present, and share Reveal.js slides on the web by using github's gist service as a datastore.
Store any Revealjs-compatible HTML or Markdown content in a gist, then append your resulting gist id to the end of any gist-reveal site url to view the resulting presentation:
http://gist-reveal.it/GIST_ID_CONTAINING_REVEALJS_SLIDE_CONTENT
Example:
http://gist-reveal.it/af84d40e58c5c2a908dd
Use bitly or another url shortener to make these long urls easier to share, and to make enagement rates easier to count.
Creating a bit.ly shortname for your longer gist-reveal/gist_id deck urls will also make your presentations available at an alternate presentation path:
http://gist-reveal.it/bit.ly/SHORTNAME
Example:
http://gist-reveal.it/bit.ly/k8s-workshops
Much nicer! Make sure to continue sending traffic to the shorter bit.ly/shortname url for metrics collection purposes.
Available CSS themes include the default reveal.js list of themes, but can be easily extended by storing new themes in a gist:
- a dark winter theme
- the revealjs black theme
- the revealjs simple theme
- the revealjs league theme
- the revealjs sky theme
Conference organizers can host their own modified gist-reveal templating service (with its own default theme), to provide a consistent look for all presentations at an event.
The following environment variables can be used to autoconfigure the application:
| Variable Name | Contents | Default Value |
|---|---|---|
| DEFAULT_GIST | The default gist id slideshow content for the site | af84d40e58c5c2a908dd |
| REVEAL_THEME | The site's default theme. Should be a locally bundled theme name, or a remote gist_id. | 450836bbaebcf4c4ae08b331343a7886 |
| GH_CLIENT_SECRET | GitHub client secret | unset |
| GH_CLIENT_ID | GitHub client ID | unset |
| GA_TRACKER | Google Analytics tracker token | unset |
| PORT | The server port number | 8080 |
| IP_ADDR | The server IP address | 0.0.0.0 |
| GIST_THEMES | Allow reveal.js CSS themes to be installed dynamically "url/?theme=gist_id". Disable this feature by setting this config to the string "false". | "true" |
| REVEAL_SOCKET_SECRET | the site's broadcast token (alphanumeric) | randomly generated |
See server.js for more information about the site's configuration options.
Administrators can configure the application's REVEAL_SOCKET_SECRET to broadcast slide transitions using Reveal's socket Multiplexing support.
Presenters who know the site's REVEAL_SOCKET_SECRET value can configure their browser as a presentation device using the setToken querystring param:
http://YOUR_REVEAL_HOST_URL/?setToken=REVEAL_SOCKET_SECRET_VALUE
This token will be stored in the browser's localStorage area (per host url) as localStorage.secret. To reconfigure your browser as a client device (as a listener), use the clearToken querystring param:
http://YOUR_REVEAL_HOST_URL/?clearToken
Gist-reveal makes it easy to run your own Gist-powered RevealJS slideshow service
The simplest way to get started with this project, is to clone a copy of the source from github (git clone http://github.com/ryanj/gist-reveal && cd gist-reveal), then run the app locally with npm install followed by npm start.
Create a kubernetes pod and service, both named gist-reveal:
kubectl run gist-reveal --image=ryanj/gist-reveal --expose --port=8080 \
--env="DEFAULT_GIST=YOUR_DEFAULT_GIST_ID" \
--env="GH_CLIENT_SECRET=YOUR_GH_CLIENT_SECRET" \
--env="GH_CLIENT_ID=YOUR_GH_CLIENT_ID" \
--env="REVEAL_SOCKET_SECRET=0P3N-S0URC3" \
--env="GA_TRACKER=YOUR_GA_TRACKER"Run the container image locally on port 8080:
podman run --rm -p 8080:8080 ryanj/gist-revealEnvironment variables can be passed into the container to configure the websocket relay, or to change the default slideshow content:
podman run --rm -p 8080:8080 -e "REVEAL_SOCKET_SECRET=0P3N-S0URC3" -e "DEFAULT_GIST=YOUR_DEFAULT_GIST_ID" ryanj/gist-revealgist-reveal.it was created at the first DockerCon Hackathon by @ryanj and @fkautz.
