Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Common code for integrating SPID authentication

Readme

io-spid-commons

This repo contains:

  • a passport-strategy that implements SPID authentication
  • a method that configures an express endpoint to serve Service Provider metadata
  • a scheduled procedure that refreshes IDP metadata from the SPID registry
  • a redis cache provider to validate SAML InResponseTo field

You may use this package if you're going to implement a SPID Service Provider with a NodeJS express server.

Upgrading passport-saml

Beware that any changes to the method signatures of SAML.prototype.generateAuthorizeRequest and SAML.prototype.validatePostResponse must be reflected inside the CustomSamlClient class.

That's why the version of passport-saml in package.json is currently fixed at 1.3.5.

Store Additional data between login and acs steps

If you need to pass additional parameters from login request to acs callback, you can use built-in additional parameter management, by adding a new extraLoginRequestParamConfig block in configuration:


export type ExtraParamsT = t.TypeOf<typeof ExtraParams>;
export const ExtraParams = t.type({ test: t.string });

const appConfig: IApplicationConfig<ExtraParamsT> = {

  extraLoginRequestParamConfig: {
    codec: ExtraParams,
    requestMapper: (req) =>  
                    ExtraParams.decode({
                                        loginType: req.header("x-test-header"),
                                      })
  },

  assertionConsumerServicePath: "/acs",
  clientErrorRedirectionUrl: "/error",
  clientLoginRedirectionUrl: "/success",
  loginPath: "/login",
  metadataPath: "/metadata",
  sloPath: "/logout",
  spidLevelsWhitelist: ["SpidL2", "SpidL3"],
};

The acs callback will receive a second parameter, containing the information extracted during login step for the user:


const acs: AssertionConsumerServiceT<ExtraParamsT> = async (
  payload,
  extraParams
  // ^^^ 
  // ExtraParamsT | undefined
) => {
  logger.info("acs:%s%s", JSON.stringify(payload), JSON.stringify(extraParams));
  return ResponsePermanentRedirect({ href: "/success?acs" } as ValidUrl);
};

NOTE: If the mapper or the coded return a validation error, extraParams will be undefined. NOTE 2: It's better to define the codec with defaults and/or partial properties, to avoid undefined values during deploy phase (ie: Data stored before the deploy that cannot be decoded with new codec because of lack of required properties)

Local development

To run the project locally with the embedded example express application run the following commands:

yarn install
yarn build
docker-compose up --build

PS. If was present locally a previously cached version of io-spid-commons docker container and you get the error Unexpected token < on node_modules/xml-encription/lib/templates/encrypted-key.tpl.xml.js, is needed to clean all the old containers datas with docker system prune --all before running the project again.
