# Hamspam
|
||||
|
||||
Hamspam is a browser extension that injects visual feedback about suspicious emails into your page.
|
||||
|
||||
## Preview
|
||||
|
||||
Hamspam scans for malware [checkpoints](#checkpoints "checkpoints") and marks all vulnerabilities with color-coded icons:
|
||||
|
||||
| Icon | Severity |
|
||||
|-|-|
|
||||
<img src="./docs/assets/img/pass.png" width="24"> | Low |
|
||||
<img src="./docs/assets/img/warning.png" width="24"> | Medium |
|
||||
<img src="./docs/assets/img/danger.png" width="24"> | High |
|
||||
|
||||
<p align="center"><img alt="" src="./docs/assets/img/preview1.png" width=49%><img alt="" src="./docs/assets/img/preview2.png" width=49%></p>
|
||||
|
||||
## Getting Started
|
||||
|
||||
### Prerequisites
|
||||
|
||||
* Node.js
|
||||
```
|
||||
$ yum install nodejs
|
||||
$ yum install npm
|
||||
```
|
||||
|
||||
* Install npm packages
|
||||
```
|
||||
npm install
|
||||
```
|
||||
|
||||
### Development
|
||||
* Watch for updates to code and compile automatically: `npm run develop`
|
||||
* Build the optimized production: `npm run build`
|
||||
* Run all unit tests: `npm run test`
|
||||
|
||||
### Usage
|
||||
|
||||
1. Create a class that extends AbstractEmail and another class that extends AbstractView.
|
||||
|
||||
2. Define those new classes in [Lib.ts](src/Lib.ts "Lib.ts")
|
||||
```
|
||||
export * from './<Email>';
|
||||
export * from './<EmailView>';
|
||||
```
|
||||
|
||||
3. Add a configuration in [config.yaml](dist/config.yaml "config.yaml")
|
||||
```
|
||||
email:
|
||||
- {name: <Email>, hostname: <email.com>, view: <EmailView>}
