Mongoose Profanity Plugin

> A plugin to auto-moderate profanity in your content.

This plugin will add a pre-save hook to your model to run a profanity check in your content, perform a chosen behaviour (Obscuring forbidden words by default), add flags to your entry and turning a blackListed field to true when the length of the field flags on your entry reaches a limit.

With default options it will obscure forbidden words in the following format: 'a*b'.

In replace mode it will replace forbidden words with random inoffensive replacement words on save.

The plugin adds the following fields to your schema:

> Moved to mongoose 4.x since version 0.2.0, for mongoose 3.x please use version 0.1.6

To install, run:

npm install mongoose-profanity

$3

Setup a 'self-moderating' model:

``javascript
var mongoose = require('mongoose'),
Schema = mongoose.Schema,
profanityPlugin = require('mongoose-profanity');

var TestSchema = new Schema({
message: String
});

TestSchema.plugin(profanityPlugin);

var Test = mongoose.model('Test', TestSchema);

var test = new Test({
message: 'What a bloody damn horrible weather, crap!'
}).save(function (err, entry) {
console.log(entry.message, entry.flags, entry.blackListed);
// 'What a b*y dn horrible day, c*p!', [ .. ], true
});
`

Only query entries which have not been blacklisted:

`javascript
Test.find({ blackListed: false }, function (err, entries) {
console.log(entries.length);
// 0
})
`

$3

`javascript
// Obscure a custom list of forbidden words with a given symbol, blacklist if 1 more are found

var mongoose = require('mongoose'),
Schema = mongoose.Schema,
profanityPlugin = require('mongoose-profanity');

var TestSchema = new Schema({
message: String,
uncheckedMessage: String
});

TestSchema.plugin(profanityPlugin, {
maxFlags: 1,
forbiddenList: [ 'politics', 'business' ],
obscureSymbol: '%',
fields: [ 'message' ]
});

var Test = mongoose.model('Test', TestSchema);

var test = new Test({
message: 'We are not allowed to talk politics or business',
uncheckedMessage: 'We can totally talk business here'
}).save(function (err, entry) {
console.log(entry.message, entry.flags, entry.blackListed);
// 'We are not allowed to talk p%%%%%%s or b%%%%%%s', [ .. ], true

console.log(uncheckedMessage);
// We can totally talk business here
});
`

$3

`javascript
// Replace a custom list of forbidden words with a custom list of replacement words, never blacklist

var mongoose = require('mongoose'),
Schema = mongoose.Schema,
profanityPlugin = require('mongoose-profanity');

var TestSchema = new Schema({
message: String
});

TestSchema.plugin(profanityPlugin, {
maxFlags: 0,
forbiddenList: [ 'google', 'bing' ],
replacementsList: [ 'some search engine' ],
fields: [ 'message' ]
});

var Test = mongoose.model('Test', TestSchema);

var test = new Test({
message: "I'd rather use Google instead of Bing"
}).save(function (err, entry) {
console.log(entry.message, entry.flags, entry.blackListed);
// 'I'd rather use some search engine instead than some search engine', [ .. ], true
});
`

$3

* fields - Array of schema fields to be checked by the plugin
* forbiddenList - Array of forbidden terms to replace or obscure
* replacementsList - Array of replacement words (To pick randomly from)
* maxFlags - Max flags before blacklisting (Prevents addition of custom fields, flagging and blacklisting if falsy)
* replace- If set to true it will replace forbidden words with innocuous replacement words
* obscureSymbol - Symbol used to obscure words if obscured is set to true

$3

* flags: FlagSchema - Flag object used by the library, open to different uses for integration (See Flag Schema)
* blackListed: Boolean - Turns to true when the length of flags is greater than configured limit (3 by default)

$3

The flag schema can be used for different purposes, in order to make the best out of the blacklist feature in your application.

The fields in the schema are the following:

* author: Mixed object, type and content left to the discretion of the user
* reason: String containing reason for the flagging. (E.g. 'Inappropriate language')

$3

Run unit-tests with npm test`. Make sure a local mongo server is running in order for the tests to run.

All contributions are welcome as long as tests are written.
