## Support
If you're a user seeking support, [here is our support site](https://metamask.helpscoutdocs.com/).
## Developing Compatible Dapps
If you're a web dapp developer, we've got two types of guides for you:
- If you've never built a Dapp before, we've got a gentle introduction on [Developing Dapps with Truffle and MetaMask](https://blog.metamask.io/developing-for-metamask-with-truffle/).
### New Dapp Developers
- We recommend this [Learning Solidity](https://karl.tech/learning-solidity-part-1-deploy-a-contract/) tutorial series by Karl Floersch.
- We wrote a (slightly outdated now) gentle introduction on [Developing Dapps with Truffle and MetaMask](https://medium.com/metamask/developing-ethereum-dapps-with-truffle-and-metamask-aa8ad7e363ba).
### Current Dapp Developers
- If you have a Dapp, and you want to ensure compatibility, [here is our guide on building MetaMask-compatible Dapps](https://github.com/MetaMask/faq/blob/master/DEVELOPERS.md)
## Building locally
@ -18,11 +30,15 @@ If you're a web dapp developer, we've got two types of guides for you:
Uncompressed builds can be found in `/dist`, compressed builds can be found in `/builds` once they're built.
## Installing Local Builds on Chrome
### Running Tests
To install your locally built extension on Chrome, [follow this guide](http://stackoverflow.com/a/24577660/272576).
Requires `mocha` installed. Run `npm install -g mocha`.
The built extension is stored in `./dist/chrome/`.
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`.
## Architecture
@ -41,126 +57,23 @@ npm start
npm run dist
```
#### In Chrome
Open `Settings` > `Extensions`.
Check "Developer mode".
At the top, click `Load Unpacked Extension`.
Navigate to your `metamask-plugin/dist/chrome` folder.
Click `Select`.
You now have the plugin, and can click 'inspect views: background plugin' to view its dev console.
#### In Firefox
Go to the url `about:debugging`.
Click the button `Load Temporary Add-On`.
Select the file `dist/firefox/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`.
For longer questions, use the StackOverfow tag `firefox-addons`.
### 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:
1. Clone the dependency locally.
2. `npm install` in its folder.
3. Run `npm link` in its folder.
4. Run `npm link $DEP_NAME` in this project folder.
5. Next time you `npm start` it will watch the dependency for changes as well!
### Running Tests
Requires `mocha` installed. Run `npm install -g mocha`.
Then just run `npm test`.
You can also test with a continuously watching process, via `npm run watch`.
You can run the linter by itself with `gulp lint`.
#### Writing Browser Tests
To write tests that will be run in the browser using QUnit, add your test files to `test/integration/lib`.
### Deploying the UI
## Other Docs
You must be authorized already on the MetaMask plugin.
0. Update the version in `app/manifest.json` and the Changelog in `CHANGELOG.md`.
1. Visit [the chrome developer dashboard](https://chrome.google.com/webstore/developer/dashboard?authuser=2).
2. Run `gulp dist` (or `gulp zip` if you've already built)
3. Upload the latest zip file from `builds/metamask-$PLATFORM-$VERSION.zip` as the updated package.
