Impress-server enables you to share an impress.js presentation with other users. It is not only a remote control, but every user who opens the presentation while it is in presentation mode, will have the state of the presentation synced in real time to his browser.
What problem does it solve ?
In our company we permanently have video conferences with customers. Whenever we want to run a presentation for them we have to do this via a screen sharing tool. Screen sharing is fine but the quality is poor and it uses a lot of bandwith. With impress-server you can run a remote presentation with nearly no bandwidth useage at all and in full impress.js quality.
In addition to that, you can use impress-server just to give you the ability to remote control your presentation with your phone or another computer.
Install via NPM:
npm install impress-server
Change into on of your impress presentation folder. Make sure to name your
index.html. All other resources for your presentation (like
images and css) should be put into this directory as well.
Impress-server needs a specific impress.js version to run presentation sharing.
Starting with impress-server 0.0.8 you no longer need to adopt your presentations html
file. Just make sure you're loading a
When everything is prepared, start the impress-server by typing:
Impress-server also takes arguments for port (-p) and directory (-d) it should serve. The server generates a password on startup which you need later to claim the presentation mode. You can provide your own password by providing a password (--pw) param at server startup.
Using a mobile device as remote control
Since version 0.0.7, impress-server supports a remote controller. To enable your phone to act as a remote, point its browser to your presentation server on the route /remote.
You now should see the remote ui. On the bottom of the page you can enter your impress-server password and claim the presentation mode. Tapping with your finger on the left/right arrows will go to the previous/next page. On Adroid (using Browser, Chrome or Firefox) you can also swipe your finger left or right to move forwards or backwards (had no chance to test this on an iPhone).
Sharing a presentation
A presentation is not shared by default but only hosted. Every user visiting your presentation can navigate the presentation himself. If you like to switch to presentation mode, you currently have to hack your way in :) .
Open your browsers web developer tools (you should know how to do this if you can create impress.js presentations) and go to console. Type the following:
The password is shown when you startup your server. If everything works a short message should be shown, telling you that you are now in presentation mode. All current and future visitors will be in view only mode from now on. They have to view the slide your browser is currently showing. So you're in god mode now :) .
There are several other api commands you can use:
// stop presentation mode, all users can navigate on their own api.releasePresenter(); // a user in view mode can exit view mode and navigate himself api.ignorePresenter(); // a user who previously ignored the presenter can refollow the presentation api.followPresenter(); // navigate the presentation api.next(); api.prev(); api.goto(2);
