Security Headers at Legal Robot

We're big fans of open source software at Legal Robot. We also know that getting security right is a tough job, so we want to share some of the useful tools we use to build and run Legal Robot and keep it secure.

We are also proud to run Legal Robot on the Meteor framework for Node.js. With this recent change, Helmet.js becomes the official recommendation for security headers in Meteor, replacing the previous Meteor browser-policy package.

One of the most helpful tools in our Meteor security toolbox at Legal Robot is Content Security Policy (CSP) — basically, our server tells the browser what code it is allowed to run and how to handle something like code injection from a malicious browser extension.

CSP can be quite tricky, but there are some excellent tools out there to help, like [Google'

Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

Use ESM yourself. (preferred)
Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
Stay on the existing version of the package until you can move to ESM.

	import { EJSON } from 'meteor/ejson';

	function getOptions(self) {
	const opts = [];
	if (self.global) opts.push('g');
	if (self.ignoreCase) opts.push('i');
	if (self.multiline) opts.push('m');
	return opts.join('');
	}
