## 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/).
|
|
- 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
|
|
|
|
- Install [Node.js](https://nodejs.org/en/) version 6.3.1 or later.
|
|
- Install local dependencies with `npm install`.
|
|
- Install gulp globally with `npm install -g gulp-cli`.
|
|
- Build the project to the `./dist/` folder with `gulp build`.
|
|
- Optionally, to rebuild on file changes, run `gulp dev`.
|
|
- To package .zip files for distribution, run `gulp zip`, or run the full build & zip with `gulp dist`.
|
|
|
|
Uncompressed builds can be found in `/dist`, compressed builds can be found in `/builds` once they're built.
|
|
|
|
## Installing Local Builds on Chrome
|
|
|
|
To install your locally built extension on Chrome, [follow this guide](http://stackoverflow.com/a/24577660/272576).
|
|
|
|
The built extension is stored in `./dist/chrome/`.
|
|
|
|
## Architecture
|
|
|
|
[][1]
|
|
|
|
## Development
|
|
|
|
```bash
|
|
npm install
|
|
npm start
|
|
```
|
|
|
|
## Build for Publishing
|
|
|
|
```bash
|
|
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 $DEP_NAME` in this project folder.
|
|
5. Next time you `npm start` it will watch the dependency for changes as well!
|
|
|
|
### Running Tests
|
|
|
|
Requires `mocha` installed. Run `npm install -g mocha`.
|
|
|
|
Then just run `npm test`.
|
|
|
|
You can also test with a continuously watching process, via `npm run watch`.
|
|
|
|
You can run the linter by itself with `gulp lint`.
|
|
|
|
#### Writing Browser Tests
|
|
|
|
To write tests that will be run in the browser using QUnit, add your test files to `test/integration/lib`.
|
|
|
|
### Deploying the UI
|
|
|
|
You must be authorized already on the MetaMask plugin.
|
|
|
|
0. Update the version in `app/manifest.json` and the Changelog in `CHANGELOG.md`.
|
|
1. Visit [the chrome developer dashboard](https://chrome.google.com/webstore/developer/dashboard?authuser=2).
|
|
2. Run `gulp dist` (or `gulp zip` if you've already built)
|
|
3. Upload the latest zip file from `builds/metamask-$PLATFORM-$VERSION.zip` as the updated package.
