The container is built in two steps (docker builder pattern):
1. Node/npm build stage
2. Final image with Nginx and static files to serve
Build the mage with this command:
docker image build -t dceware .
Run a container with this command:
docker run --rm -p 8080:80 dceware
Then you can visit your local diceware at:
http://localhost:8080/

Diceware
Feel free to check out the live version at https://diceware.dmuth.org/
Weak passwords are a big flaw in computer security due to a lack of "entropy" or randomness. For example, how many times have you used the name of a pet or relative or street in a password, or perhaps the number "1". Not very random, is it? :-) Worse still, if passwords are reused between services, that increases your security risk.
Fact is, humans are terrible at remembering random combiations of letters and numbers, but we are great at remembering phrases of words. That's where Diceware comes in.
Diceware is based on the proposal at http://world.std.com/~reinhold/diceware.html wherein virtual dice are roled 5 times, and the 5 digit number used against a lookup table of words. 4 dice rolls gives you 4 random words which are easy for a human being to remember, yet have a high amount of entropy which makes them hard to crack.

Can I run this on my own computer without using your website?
Yes! Go to https://github.com/dmuth/diceware/releases and download the latest diceware.zip file.
When you unzip that file, the contents will be written to a directory called diceware/. You
can then point a webserver on your machine to diceware/index.html in order to use Diceware.
Sadly, you cannot open diceware/index.html directly, as the CORS policy in Chrome prevents that.
If you know of a way to fix that, please open an issue. :-)
Will this work on an iPhone?
Yep! It should work on any mobile phone or tablet that supports Javascript, but I have only tested it on an iPhone 5S at this time.
Will this work in an air-gapped environment?
Yes, copies of assets such as Bootstrap and jQuery have been made, and Diceware can now be run without requiring an Internet connection.
Development
This app is built with Webpack.
When done editing main.js, the packed file can be built by simply running webpack
on the command line. It will be writing to dist/bundle.js. To run webpack in a
mode so that it regularly checks for changed files, run webpack --watch --mode development.
In a move that departs from Best Practices, I have made the decision to include the packed file in Git. My reason for this is that the software will be ready to run as soon as it is checked out (or a ZIP is downloaded), and that is a key design feature of this app--I want it to be as easy to get up and running as possible.
A local webserver can be set up by running npm install http-server -g to install it, then http-server to listen on http://localhost:8080/
In summary:
- Development
npm run clean- Cleanup after a previous runnpm install- Install NPM packages used by Dicewarenpm run dev-build- Run webpack to pack Javascript files and watch for changes.http-servervim src/lib.js src/index.js- Be sure to check in your changes before the next step!
- Testing
rm -fv src/index.js && git co src/index.js- Get the new SHA1 hash that will be displayed in debug messages.- The hash can be crosschecked with the results of
git hash-object src/index.js
- The hash can be crosschecked with the results of
npm test- Make sure you didn't break any of the core logic!npx cypress run- Run front-end testing- If the tests break, run
npx cypress opento run tests interactively.
- If the tests break, run
- Deployment
npm run build- Webpack Javscript files in production mode (smaller file but takes longer)./go-sync-to-s3.sh- Do this if you're me, to upload to S3. If you're not me, you'll need to do something else, or possibly nothing at all.
In practice:
npm run clean; npm run dev-build- Run webpack in dev mode while working on Javascripthttp-server- Stand up a local HTTP servervim src/lib.js src/index.jsrm -fv src/index.js && git co src/index.js
npm run clean; npm run build- Run webpack in prod mode to produce final Javascript bundle./go-sync-to-s3.sh- Do this if you're me, to upload to S3. If you're not me, you'll need to do something else, or possibly nothing at all.
Releasing a New Build
npm run release-buildto create the ZIP filediceware.zipwith all assets in it, includingbundle.jsand the contents ofnode_modules/.gh release create v1.0.1to upload a release to https://github.com/dmuth/diceware/releases.- Change the tag for the version number accordingly.
