# Development
|
|
|
|
Several files which are needed for developing on MetaMask.
|
|
|
|
Usually each file or directory contains information about its scope / usage.
|
|
|
|
## Segment
|
|
|
|
### Debugging with the Mock Segment API
|
|
|
|
To start the [Mock Segment API](./mock-segment.js):
|
|
|
|
- Add/replace the `SEGMENT_HOST` and `SEGMENT_WRITE_KEY` variables in `.metamaskrc`
|
|
```
|
|
SEGMENT_HOST='http://localhost:9090'
|
|
SEGMENT_WRITE_KEY='FAKE'
|
|
```
|
|
- Build the project to the `./dist/` folder with `yarn dist`
|
|
- Run the Mock Segment API from the command line
|
|
```
|
|
node development/mock-segment.js
|
|
```
|
|
|
|
Events triggered whilst using the extension will be logged to the console of the Mock Segment API.
|
|
|
|
More information on the API and its usage can be found [here](./mock-segment.js#L28).
|
|
|
|
### Debugging in Segment
|
|
|
|
To debug in a production Segment environment:
|
|
|
|
- Create a free account on [Segment](https://segment.com/)
|
|
- Create a New Workspace
|
|
- Add a Source (Node.js)
|
|
- Copy the `Write Key` from the API Keys section under Settings
|
|
- Add/replace the `SEGMENT_HOST` and `SEGMENT_WRITE_KEY` variables in `.metamaskrc`
|
|
```
|
|
SEGMENT_HOST='https://api.segment.io'
|
|
SEGMENT_WRITE_KEY='COPIED_WRITE_KEY'
|
|
```
|
|
- Build the project to the `./dist/` folder with `yarn dist`
|
|
|
|
Events triggered whilst using the extension will be displayed in Segment's Debugger.
|
|
|
|
### Debugging Segment requests in MetaMask
|
|
|
|
To opt in to MetaMetrics;
|
|
- Unlock the extension
|
|
- Open the Account menu
|
|
- Click the `Settings` menu item
|
|
- Click the `Security & Privacy` menu item
|
|
- Toggle the `Participate in MetaMetrics` menu option to the `ON` position
|
|
|
|
You can inspect the requests in the `Network` tab of your browser's Developer Tools (background.html)
|
|
by filtering for `POST` requests to `/v1/batch`. The full url will be `http://localhost:9090/v1/batch`
|
|
or `https://api.segment.io/v1/batch` respectively.
|
|
|
|
## Sentry
|
|
|
|
### Debugging in Sentry
|
|
|
|
To debug in a production Sentry environment:
|
|
|
|
- If you have not already got a Sentry account, you can create a free account on [Sentry](https://sentry.io/)
|
|
- Create a New Sentry Organization
|
|
- If you already have an existing Sentry account and workspace, open the sidebar drop down menu, then click `Switch organization` followed by `Create a new organization`
|
|
- Create a New Project
|
|
- Copy the `Public Key` and `Project ID` from the Client Keys section under your projects Settings
|
|
- Select `Settings` in the sidebar menu, then select `Projects` in the secondary menu. Click your project then select `Client Keys (DSN)` from the secondary menu. Click the `Configure` button on the `Client Keys` page and copy your `Project Id` and `Public Key`
|
|
- Add/replace the `SENTRY_DSN` and `SENTRY_DSN_DEV` variables in `.metamaskrc`
|
|
```
|
|
SENTRY_DSN_DEV=https://{SENTRY_PUBLIC_KEY}@sentry.io/{SENTRY_PROJECT_ID}
|
|
SENTRY_DSN=https://{SENTRY_PUBLIC_KEY}@sentry.io/{SENTRY_PROJECT_ID}
|
|
```
|
|
- Build the project to the `./dist/` folder with `yarn dist`
|
|
|
|
Errors reported whilst using the extension will be displayed in Sentry's `Issues` page.
|
|
|
|
## Source Maps
|
|
|
|
### Debugging production builds using Source Maps
|
|
|
|
To unbundle the extensions compiled and minified JavaScript using Source Maps:
|
|
|
|
- Open Chrome DevTools to inspect the `background.html` or `home.html` view
|
|
- Click on the `Sources` tab in Chrome DevTools
|
|
- In the Sources tab, click on the `Page` panel
|
|
- Expand the file directory in the Page panel until you see the source files you're after
|
|
- Select a source file in the Page panel
|
|
```
|
|
chrome-extension://{EXTENSION_ID}/common-0.js
|
|
```
|
|
- Double click the source file to open it in the Workspace
|
|
- Right click in the body of the source file and select `Add source map...`
|
|
- Enter the path to the corresponding source map file, and Click `Add`
|
|
```
|
|
file:///{LOCAL_FILE_SYSTEM}/metamask-extension/dist/sourcemaps/common-0.js.map
|
|
```
|
|
- Repeat the steps above as necessary adding all the relevant source map files
|
|
- Your source maps should now be added to the DevTools Console, and you should be able to see your original source files when you debug your code
