Usage

It's very easy configure on your application. just follow on below:

let app = require("password-meter-pro");

app.password_strength("1111") # return  message = "Very Weak" , strength = 14  , percentage = 11%

app.password_strength("aaaa") # return  message = "Very Weak" , strength = 19 , percentage = 15%

app.password_strength("####") # returns message = "Very Weak" , strength = 21 , percentage = 17%

app.password_strength("banglad") # returns message = "Weak" , strength = 33  , percentage = 26%

app.password_strength("bangla1") # returns message = "Good" , strength = 37  , percentage = 29%

app.password_strength("bangladesh") # returns message = "Good" , strength = 48 , percentage = 38%

app.password_strength("bangla1desh") # returns message = "Good" , strength = 57 , percentage = 45%

app.password_strength("Bangla1desh") # returns message = "Strong", strength = 66, percentage = 52%

app.password_strength("Bangladesh#") # returns message = "Strong", strength = 71, percentage = 56%

app.password_strength("Bangla1desh#") # returns message = "Strong", strength = 79, percentage = 62%

app.password_strength("Hello71*Bangla1desh#") # returns message = "Very Strong" , strength = 132  , percentage = 100%

There are some default messages, if you need to configure your own message like "Very week" instead of "You should use strong password", you can do easily here:

// Example: default messages of package, 
{
    VERY_WEAK: "Very Weak",
    WEAK: "Weak",
    GOOD: "Good",
    STRONG: "Strong",
    VERY_STRONG: "Very Strong"
}

You can override these message by using "message" method:

app.message({
    VERY_WEAK: "You should use strong password",
});

app.password_strength("####") # returns 'You should use strong password'
//or
app.message({
    VERY_WEAK: "You should use strong password",
}).password_strength("####") # returns 'You should use strong password'

There are some default configs for checking validating items on password. if you want to customer that too, you can use "config" method.

// Default configs
{
    SMALL_LETTER : {
        min: 0,
        max: 26
    },
    CAPITAL_LETTER : {
        min: 0,
        max: 26
    },
    NUMERIC: {
        min: 0,
        max: 255
    },
    SPECIAL_CHAR: {
        min: 0,
        max: 33
    } 
}

You can override these configs:

app.config({
    // always checking length of given item of each type
    NUMERIC: {
        min: 2,
        max: 6
    },
});

app.password_strength("####") # returns 'Numeric letter must be min: 2 and max: 6'
//or
app.config({
    NUMERIC: {
        min: 2,
        max: 6
    }
}).password_strength("####") # returns 'Numeric letter must be min: 2 and max: 6'
