koa-xlusca
Web application security middleware for the latest koa 2.x.
Fork from koa-lusca,
It's a pity that koa-lusca is out of maintenances for over 3 years, so i made this fork and re-released it as koa-xlusca, and let's keep it fresh.
Usage
const Koa = require('koa');
const lusca = require('koa-xlusca');
const app = new Koa();
app.use(lusca({
csrf: true,
csp: { /* ... */},
xframe: 'SAMEORIGIN',
p3p: 'ABCDEF',
hsts: { maxAge: 31536000, includeSubDomains: true },
xssProtection: true,
referrerPolicy: 'same-origin'
}));
Setting any value to false
will disable it. Alternately, you can opt into methods one by one:
app.use(lusca.csrf());
app.use(lusca.csp({/* ... */}));
app.use(lusca.xframe({ value: 'SAMEORIGIN' }));
app.use(lusca.p3p({ value: 'ABCDEF' }));
app.use(lusca.hsts({ maxAge: 31536000 });
app.use(lusca.xssProtection();
app.use(lusca.referrerPolicy('same-origin'));
