Web hygiene

In the fast-evolving world of technology, managing web content effectively is often a complex, multifaceted task. As a tech lead for a large international technology company, I’ve come to recognize the importance of not just keeping up with technological advancements, but also maintaining a standard I like to call “web hygiene.” While not an official industry term, web hygiene captures an essential, holistic approach to how we create, maintain, and protect our web presence.

DALL·E

What is Web Hygiene?

Web hygiene is a practice that embodies the principles and actions necessary to maintain a healthy, compliant, and user-centric online environment. It’s not just about flashy features or impressive performance metrics—it’s about ensuring that every part of our web content adheres to certain standards that safeguard users, support accessibility, and uphold our company’s reputation.

The term itself, “hygiene,” implies cleanliness and routine care—much like personal hygiene is a baseline for health and social interactions, web hygiene is the baseline for maintaining a trustworthy, robust, and inclusive web presence.

The Core Pillars of Web Hygiene

Web hygiene is not just one aspect of web management; it’s a cohesive practice that spans several critical areas:

1. Accessibility

An inclusive web experience is not just a compliance checkbox; it’s a commitment to enabling all users to engage with our content. Meeting WCAG standards ensures that people with disabilities can navigate, read, and interact with our sites seamlessly. Proper web hygiene integrates accessibility into every stage of design and development, making it part of the DNA of our content creation.

2. Data Collection and PII (Personally Identifiable Information)

Data is a powerful asset, but with great power comes great responsibility. Web hygiene means that any data we collect adheres strictly to privacy laws and ethical standards. This involves implementing transparent consent mechanisms, anonymizing data wherever possible, and maintaining a secure infrastructure to protect against breaches. The trust we build through responsible data collection cannot be understated—it’s what sets leading technology companies apart from those who cut corners.

3. Maintenance and Upkeep

Web hygiene demands regular maintenance. This includes routine security audits, updates, and testing to ensure that we’re proactively closing vulnerabilities and optimizing performance. The idea here is to prevent problems before they arise—keeping the web infrastructure as healthy as possible to avoid breakdowns that could compromise user experience and trust.

4. Content Quality

Even the most secure, accessible, and well-maintained site can fall flat if the content is subpar. Good web hygiene includes having clear guidelines for writing effective, relevant, and engaging content. This means avoiding jargon, staying concise, and keeping the end user in mind at all times. Content should be easy to read, informative, and updated as needed to reflect current information and practices.

Training and Access Control

To uphold web hygiene, it’s crucial that all web content creators and site owners undergo an access course or training before being given the keys to their own subdomain or access to an existing one. This training ensures they understand the fundamentals of web hygiene, including accessibility, data handling, and content standards. This process will be tracked, and refresher sessions will be offered to maintain their access over time, reinforcing a culture of continuous learning and adherence to best practices.

Automated Tools and Monitoring

Web hygiene extends beyond human practices. Automated tools can be employed to scan websites and provide feedback on compliance with accessibility, security, and content quality. These tools serve as a proactive measure, highlighting potential issues before they escalate and ensuring that web hygiene standards are consistently met.

Why Web Hygiene Matters

You might wonder, why not just let creators and site owners do what they please? Isn’t creativity key? While creative freedom is important, in a large-scale organization, it must coexist with responsible practices. Poor web hygiene leads to a host of issues—ranging from accessibility complaints and data privacy violations to decreased trust and engagement. In an environment where a single oversight can cascade into serious reputational damage, maintaining web hygiene isn’t just good practice—it’s a business imperative.

Taking a Holistic Approach

Web hygiene isn’t a one-time checklist or a static policy; it’s a dynamic, ongoing process that involves cross-functional teams, including developers, content strategists, legal advisors, and security experts. It requires a shared understanding and commitment across the organization to do what’s right—even when no one is watching.

It’s about creating a culture where web hygiene is as natural as locking the doors when you leave a building. When every team member understands their role in maintaining these standards, we foster a healthier web presence that’s not just compliant, but also resilient and respected.

In the end, web hygiene represents a commitment to quality, integrity, and inclusivity that benefits both the company and its users. It’s about setting the bar higher and making sure that we’re doing more than the bare minimum—we’re upholding the values that make our digital spaces trustworthy and sustainable for all.

NPM Dependency Notation – idiots guide

Dependency notation in the package.json file influences how npm handles version installations, and this affects whether npm install may update the package-lock.json file.

Here’s how it works based on different notations:

Version Notations and Their Meanings:

  1. Exact Version (“4.19.2”):
  • Notation: “4.19.2”
  • Meaning: Install exactly version 4.19.2 of the package.
  • Effect on npm install:
  • When this version is specified, npm will always install version 4.19.2, regardless of whether newer minor or patch versions are available. The package-lock.json will not be updated unless you manually change the version in package.json.
  • Example: If version 4.19.3 is available, npm will not install it.


2. Caret (^) Notation (“^4.19.2”):

  • Notation: “^4.19.2”
  • Meaning: Install any compatible version according to semver rules, meaning any version >=4.19.2 and <5.0.0.
  • Effect on npm install:
  • With ^, npm allows updates to the minor and patch versions, but not the major version. This means if a newer patch version (like 4.19.3) or minor version (like 4.20.0) is available, npm will install it. If an update is installed, the package-lock.json will be updated to reflect the new version.
  • Example: If 4.20.1 is available, npm install will update package-lock.json to install 4.20.1.


3. Tilde (~) Notation (“~4.19.2”):

  • Notation: “~4.19.2”
  • Meaning: Install the most recent patch version that matches the specified minor version, meaning any version >=4.19.2 and <4.20.0.
  • Effect on npm install:
  • With ~, npm will allow updates to the patch version but not the minor version. If a newer patch version is available (e.g., 4.19.3), npm will install it, and the package-lock.json will be updated.
  • Example: If version 4.19.5 is available, npm will install that, but it will not install version 4.20.0.


4. Major Version (“4.19”):

  • Notation: “4.19”
  • Meaning: This implies “4.19.x”, which means install the latest available patch version within the 4.19.x range.
  • Effect on npm install:
  • This is similar to using ~4.19.0 but more permissive. It allows updates within the minor version and to any patch version (e.g., 4.19.2 → 4.19.5).
  • Example: If version 4.19.3 or 4.19.5 is available, npm will install it and update package-lock.json.


Impact on npm install and package-lock.json:

  • Exact version (“4.19.2”): No updates will occur unless you change the version manually in package.json.
  • Caret (^4.19.2) or Major version (“4.19”): Newer patch or minor versions will be installed automatically, and this will update package-lock.json with the exact version.
  • Tilde (~4.19.2): Only patch updates are allowed, and package-lock.json will reflect those updates when they occur.


How This Affects npm install:


If you use npm install (as opposed to npm ci), and the notation in your package.json allows for updates (like ^4.19.2), npm may install a newer version within the range, and as a result, the package-lock.json file will be updated with this new version.

On the other hand, if the package-lock.json specifies a version (say 4.19.2), and your package.json allows updates (^4.19.2), running npm install could still install a newer version (like 4.19.3), which would then update the lock file.

This flexibility is a double-edged sword: it allows for automatic updates of patches and minor versions, but if not managed well, it can lead to differences in installed versions across environments, which is why many teams prefer using npm ci in CI/CD pipelines for consistency.

NPM install, ci and audit

Image created by ChatGPT

I needed to take a step back and fully understand this issue so I could explain it clearly to both new and experienced developers. The problem surfaced because our deployment pipelines run npm audit, which became a bottleneck in our process. We kept seeing the same vulnerabilities flagged repeatedly, even though they had been fixed multiple times.

Here we go, npm instal, ci and audit

Here’s an overview of the flow from installing a new package with npm to running npm install or npm ci in a pipeline, along with details on how vulnerabilities may resurface through npm audit.

Flow from Installing a Package to CI/CD

  1. Installing a Package:
  • When you install a new package locally (e.g., npm install package-name), npm adds the package to the node_modules directory and updates your package.json and package-lock.json files (or yarn.lock if you use Yarn).
  • package.json specifies the declared dependencies and their versions.
  • package-lock.json contains the exact versions of the installed packages and their entire dependency tree (including transitive dependencies). This ensures that everyone who installs your project gets the same versions of dependencies.

2. Pushing to Version Control:

  • Once you are satisfied with your code, including the new dependency, you push the changes to version control (e.g., Git). It’s important that both the package.json and package-lock.json files are committed to ensure consistency across environments.


3. Pipeline – npm install vs npm ci:

  • npm install:
    • During a build or deployment pipeline, running npm install will install dependencies based on the package.json and update the node_modules directory.
    • If a package-lock.json file exists, npm tries to install exact versions from the lock file, but if it detects any changes (e.g., new versions of dependencies or conflicts), it may update the lock file. (See dependency notation)
  • npm ci:
    • In a CI/CD pipeline, npm ci is preferred as it is faster and more deterministic.
    • It strictly adheres to the versions specified in package-lock.json. If any discrepancies (such as missing or extra dependencies) are found, the entire node_modules directory is deleted, and the exact dependencies from the package-lock.json are installed.
    • npm ci does not update package-lock.json, making it ideal for CI environments where reproducibility is critical.


4. npm audit:

  • During or after the install process, npm may run npm audit to check for security vulnerabilities in your dependencies. It compares the installed packages against a database of known vulnerabilities and flags any risks.
  • npm audit fix can automatically update vulnerable dependencies to the latest non-breaking versions (as defined by semver).


How Do npm audit Problems Reappear?

  1. Indirect Dependencies (Transitive Dependencies):
  • Most npm packages rely on other packages (dependencies of dependencies), and vulnerabilities often arise in these indirect dependencies.
  • Even if you’ve addressed an issue by updating your direct dependencies, some transitive dependencies may still have unresolved issues. This happens because they may not have yet released a fixed version.


2. New Vulnerabilities Discovered:

  • Sometimes, new vulnerabilities are discovered in packages that were previously considered safe. When npm’s vulnerability database is updated, a previously resolved issue may reappear if it’s related to a newly discovered flaw.


3. Out-of-Date Dependencies:

  • When the package-lock.json or a specific package hasn’t been updated for a while, and a vulnerability was later fixed in a newer version, your audit might flag the outdated dependency.
  • Running npm audit regularly (especially on pipelines) will catch such vulnerabilities, but sometimes an older transitive dependency may bring back the issue.


4. Partial Fixes:

  • Sometimes, packages release partial fixes, where only certain issues are resolved. If the fix doesn’t cover all security concerns, npm audit may still flag the package.


5. Conflicts Between Versions:

  • Certain updates may not be backward compatible with your project’s current environment or with other dependencies. This can lead to situations where you are unable to fully update vulnerable dependencies without breaking something else in your codebase.


Dealing with Persistent npm audit Problems:

  • Explicit Version Control: Sometimes you may have to manually control the versions in package-lock.json by using specific version ranges or resolutions (in tools like Yarn) to enforce the use of patched versions.
  • Selective Fixing: If you know a particular vulnerability doesn’t affect your project (e.g., it only impacts a feature you don’t use), you can audit it with exceptions.
  • Monitor Transitive Dependencies: Regularly check your dependency tree to monitor transitive dependencies and see if any have lagging versions. This can be done using tools like npm ls or through dependency-checking platforms.

Development questions…

I’ve been working on compiling a set of questions we should ask at the outset of each new feature. In my experience, teams often become laser-focused on coding and implementing new features without considering the broader context. I believe it’s crucial to be proactive and demonstrate the value of our work to the company, as ultimately, the bottom line is what matters most.

For every new feature, let’s ensure we ask these questions. The responses we gather can then inform the creation of tickets and specifications, ensuring that we’re aligned with both technical requirements and organizational objectives.

API development: Lazy tip # 25

TL;DR;

Use cURL and pipe to json_pp “| json_pp

So for the longest time when working on API’s my process would look like this:

  • Write code in Visual Studio Code
  • Change to Postman and click send (try again as Nodemon has not finished restarting)
  • Check result
  • Change back to Visual Studio Code
  • Repeat

But now its

  • Write code in Visual Studio Code
  • In the Visual Studio Code terminal press ‘up arrow’ then ‘return’
  • Check result
  • Repeat

This has speeded up my development and reduced frustration.

How?
In the terminal I make use of cURL and append the command with | json_pp

For example

curl --location --request POST 'localhost:61100/my-service/report/progress' \
--header 'Authorization: <token> \
--header 'Content-Type: application/json' \
--data-raw '{"ids":["5d765d10a13c116f3ce44d04","62bc1433eb87da610a436a48","62bc7a1147f2e0f3854aa268","62bc2dd747f2e04f724a9e26"]}' | json_pp

Top tip:

Use postman on the first iteration, then use it to export cURL command
