Building locally
- Install Node.js version 6 or later.
- Install local dependencies with
npm install
. - Install gulp globally with
npm install -g gulp
. - Build the project to the
./dist/
folder withgulp build
. - Optionally, to rebuild on file changes, run
gulp dev
.
Architecture
Development
npm install
Developing with Gulp
We're using an experimental version of gulp-cli
, so if you have the old version of gulp, you'll need to uninstall it, npm uninstall -g gulp
, and install this one instead:
npm install gulpjs/gulp-cli#4.0 -g
After that, you can just:
gulp dev
In Chrome
Open Settings
> Extensions
.
Check "Developer mode".
At the top, click Load Unpacked Extension
.
Navigate to your metamask-plugin/dist
folder.
Click Select
.
You now have the plugin, and can click 'inspect views: background plugin' to view its dev console.
In Firefox (Developer Edition Only)
Go to the url about:debugging
.
Click the button Load Temporary Add-On
.
Select the file dist/manifest.json
.
You can optionally enable debugging, and click Debug
, for a console window that logs all of Metamask's processes to a single console.
If you have problems debugging, try connecting to the IRC channel #webextensions
on irc.mozilla.org
.
Developing on UI Only
You can run npm run ui
, and your browser should open a live-reloading demo version of the plugin UI.
Some actions will crash the app, so this is only for tuning aesthetics, but it allows live-reloading styles, which is a much faster feedback loop than reloading the full extension.
Developing on UI with Mocked Background Process
You can run npm run mock
and your browser should open a live-reloading demo version of the plugin UI, just like the npm run ui
, except that it tries to actually perform all normal operations.
It does not yet connect to a real blockchain (this could be a good test feature later, connecting to a test blockchain), so only local operations work.
You can reset the mock ui at any time with the Reset
button at the top of the screen.
Developing on Dependencies
To enjoy the live-reloading that gulp dev
offers while working on the web3-provider-engine
or other dependencies:
- Clone the dependency locally.
npm install
in its folder.- Run
npm link
in its folder. - Run
npm link $DEP_NAME
in this project folder. - Next time you
gulp dev
it will watch the dependency for changes as well!
Running Tests
Requires mocha
installed. Run npm install -g mocha
.
Then just run npm test
.
You can also test with a continuously watching process, via npm run watch
.
You can run the linter by itself with gulp lint
.
Deploying the UI
You must be authorized already on the MetaMask plugin.
- Update the version in
app/manifest.json
and the Changelog inCHANGELOG.md
. - Visit the chrome developer dashboard.
- Zip the
dist
folder in this repository. - Upload that zip file as the updated package.
