web development – headless CMS: why is it better than a simple database connection?

Ok i read a lot of articles on headless / uncoupled However, I cannot understand how it should be better than a simple database connection.

From what I got so far, the main advantage of a headless CMS is that it is not connected to a specific front-end, so the content can be used and accessible by different devices such as watches, browsers, applications, IoT, etc. .

So without head would:

back end –> stores content in database –> API –> different front-ends for watches, browsers, apps, IoT etc.

Y traditional would:

back end –> stores content in database –> different front-ends for watches, browsers, apps, IoT, etc.

(?)

My question: Why implement the additional API layer, when each front device can simply extract data from a database anyway?

Simply by extracting the data from a database, you are also not restricted to a specific front-end programming language, you can use the language you want.

web browser: how does a web client verify the signing authority of a server certificate?

The public keys of the certification authorities are stored locally for each applicant in the system.

For example, in Debian GNU / Linux:

$ dpkg -l|grep -i ca-certificates
ii  ca-certificates                       20190110                        all          Common CA certificates
ii  ca-certificates-java                  20190909                        all          Common CA certificates (JKS keystore)

When you look ca-certificates content:

$ dpkg -L ca-certificates|head -n30
/.
/etc
/etc/ca-certificates
/etc/ca-certificates/update.d
/etc/ssl
/etc/ssl/certs
/usr
/usr/sbin
/usr/sbin/update-ca-certificates
/usr/share
/usr/share/ca-certificates
/usr/share/ca-certificates/mozilla
/usr/share/ca-certificates/mozilla/ACCVRAIZ1.crt
/usr/share/ca-certificates/mozilla/AC_RAIZ_FNMT-RCM.crt
/usr/share/ca-certificates/mozilla/Actalis_Authentication_Root_CA.crt
/usr/share/ca-certificates/mozilla/AddTrust_External_Root.crt
/usr/share/ca-certificates/mozilla/AffirmTrust_Commercial.crt
/usr/share/ca-certificates/mozilla/AffirmTrust_Networking.crt
/usr/share/ca-certificates/mozilla/AffirmTrust_Premium.crt
/usr/share/ca-certificates/mozilla/AffirmTrust_Premium_ECC.crt
/usr/share/ca-certificates/mozilla/Amazon_Root_CA_1.crt
/usr/share/ca-certificates/mozilla/Amazon_Root_CA_2.crt
/usr/share/ca-certificates/mozilla/Amazon_Root_CA_3.crt
/usr/share/ca-certificates/mozilla/Amazon_Root_CA_4.crt
/usr/share/ca-certificates/mozilla/Atos_TrustedRoot_2011.crt
/usr/share/ca-certificates/mozilla/Autoridad_de_Certificacion_Firmaprofesional_CIF_A62634068.crt
/usr/share/ca-certificates/mozilla/Baltimore_CyberTrust_Root.crt
/usr/share/ca-certificates/mozilla/Buypass_Class_2_Root_CA.crt
/usr/share/ca-certificates/mozilla/Buypass_Class_3_Root_CA.crt
/usr/share/ca-certificates/mozilla/CA_Disig_Root_R2.crt
(...)

Each file contains a certificate, for example:

 cat /usr/share/ca-certificates/mozilla/Amazon_Root_CA_2.crt
-----BEGIN CERTIFICATE-----
MIIFQTCCAymgAwIBAgITBmyf0pY1hp8KD+WGePhbJruKNzANBgkqhkiG9w0BAQwF

9jVlpNMKVv/1F2Rs76giJUmTtt8AF9pYfl3uxRuw0dFfIRDH+fO6AgonB8Xx1sfT

-----END CERTIFICATE-----

The syntax you mentioned for Curl is if you want to override the certificate store for the entire system to, for example, use your own certification authority.
Is named bundle because you can have several certificates involved in the signing process. For example: "Root CA" – sign -> "Intermediate CA" – sign -> Final Certificate, so in this case, your package must contain both "Root CA" and "Intermediate CA" to successfully verify every string.

usability study: can web analytics tools track user behavior on all tabs?

Yes, absolutely (or their owners) can.

Web analysis tools such as Google Analytics, content personalization services such as Maxymiser or Test & Target rely on cookies, unique to a browser, not a tab, to calculate a session.

In fact, it would be quite difficult to have Google Analytics track activity on the same site at the same time in a new tab as a new session, for the web analyst it would simply look like a new page view on the same visit.

For more information, this is how Google Analytics calculates a session; http://www.kaushik.net/avinash/standard-metrics-revisited-time-on-page-and-time-on-site/.

If you are looking for additional privacy; A new browser, preferably in a private browser / incognito window is a better bet.

I hope that helps!

Are the following two ways to obtain server certificates for web servers to host web applications?

That makes certbot do?

certbot It is a program of Let & # 39; s Encrypt, which automates the certification process. The command you published generates a certificate signing request (CSR) for the domains your_domain Y www.your_domain. Let & # 39; s Encrypt servers try to contact your instance of certbot through those domains. If successful, this proves that you really own those domains and, therefore, are eligible to generate certificates for them.

Also, automatically configure nginx to serve over HTTPS and use these certificates. These certificates will be accepted as legitimate by all modern browsers.

That makes dotenv do?

dotenv generates a self-signed certificate. These are useful for development purposes, where you don't expect someone to try and forge your connection. Most likely, you connect to localhost anyway

As a result, while those certificates are real certificates that you can use to test your HTTPS configuration, all browsers will warn you that these certificates are not reliable. You can ignore these warnings, and some browsers even allow options to ignore untrusted certificates in localhost (for example, Chrome & # 39; s allow-insecure-localhost flag), or you can manually mark this certificate as verified.

Of course, the purpose of such certificates is debugging and testing. You should never use such certificates in a production environment.

Do they work on web servers or web applications?

The task of a web server is to handle incoming connections, analyze the HTTP request and then pass it to the web application. Therefore, the server is the one that handles the things of TLS, such as what version of TLS to offer and what encryption should be offered.

Your couldIn theory, let a web application do that, but why would you do it? The application focuses on what a user does, not on the technical core of the connection.

Can you exchange both?

Yes. certbot Y dotenv They are not linked to Ubuntu. You can use each application as you see fit for your use case, as described above.

Insurance. certbot generates a certificate ready for production, but requires an external domain. dotenv generates a self-signed certificate for development. This is not for production use, but can be generated on your own.

Your web server is the one that handles all the things of certificates and TLS. Your web application is the one that handles logic. It is completely independent if called through HTTP or HTTPS.

You can use any certbot or dotenv, or even openssl to generate a self-signed certificate. The choice is based on what you need from a certificate.
