Designing A Simple Content Management System From Scratch
A content management system can begin as a modest answer to a practical problem: storing articles, editing them safely, and presenting them through a predictable website. The first useful version does not need a visual page builder, a marketplace of extensions, or a complicated publishing workflow. It needs a clear model for content, a reliable way to retrieve it, and enough safeguards to protect both the site and its users.

Building such a system from scratch is a valuable exercise for developers because it exposes the decisions hidden behind familiar software. A CMS combines database design, authentication, routing, templating, file handling, search, caching, and editorial process. Keeping the scope deliberately small makes those decisions visible and creates a foundation that can grow without becoming difficult to understand.
Define The Editorial Boundary
The first design decision is deciding what the system will manage. A small editorial site might need articles, authors, categories, tags, images, drafts, scheduled publication, and basic revisions. It probably does not need an online shop, a forum, real-time collaboration, or a page builder in its first release. Every feature increases the number of states the application must handle and the number of tests required to keep it dependable.
A useful starting point is a written content model. An article could contain an internal numeric or UUID identifier, title, slug, summary, body, status, author, publication date, creation time, and modification time. Status values such as draft, review, published, and archived are more useful than a simple published flag because they describe the editorial journey. A slug should be unique, stable, and suitable for a human-readable URL.
The distinction between content and presentation deserves attention early. Store the article’s meaning in a structured form, then let templates decide how it appears. Markdown can be a sensible choice for a small technical publication, while sanitised HTML may suit editors who need formatting controls. Mixing layout fragments directly into database fields makes future redesigns harder and can create security problems when untrusted markup is displayed.
Choose A Small, Durable Architecture
A simple monolithic application is usually a sensible first architecture. One process can handle HTTP requests, authentication, database access, template rendering, and an administrative interface. This arrangement is easier to deploy and debug than a collection of services, particularly for a small organisation running on a modest virtual server in Sydney, Melbourne, or a regional Australian data centre.
The application should still have distinct internal layers. Routing maps URLs to handlers, handlers validate input and coordinate work, repository or model code communicates with the database, and templates render output. The boundaries need not be elaborate. Their purpose is to stop SQL queries, permission checks, and HTML formatting from being scattered throughout every page.
Choose technologies that match the team’s maintenance ability rather than current fashion. A relational database such as PostgreSQL or MySQL is well suited to articles, users, and relationships between records. Server-rendered HTML can deliver a fast experience over variable NBN connections and avoids adding a large JavaScript application where it provides little value. Progressive enhancement can add previewing or autosave later without making the public site dependent on client-side scripting.
Configuration should live outside the source code. Database credentials, session secrets, mail settings, and storage paths belong in protected environment configuration. Development, staging, and production should have separate databases and credentials. A repeatable deployment process, with database migrations under version control, is more valuable than a complex build pipeline for a small CMS.
Design The Data And Publishing Workflow
The database schema should preserve the history and relationships that matter to editors. A users table can store identity and role information, while articles stores the current version of each item. Categories and tags can use separate tables with join tables for many-to-many relationships. Unique constraints on usernames, email addresses, and slugs should enforce rules at the database level as well as in application code.
Revisions are worthwhile even in a small system. Rather than overwriting the only copy of an article, save a revision when an editor makes a substantial change or submits a draft for review. A revision can contain the body, title, author, and timestamp. The published record then points to the version currently visible to visitors. This provides a basic audit trail and makes accidental deletion recoverable.
The editorial workflow should be explicit. An author might create a draft, an editor might approve it, and the system might publish it immediately or at a scheduled time. Permission checks must apply to every transition, not merely to the buttons shown in the administration screen. A user who can edit an article should not automatically be able to publish it unless that role is intended to have both powers.
Dates require careful handling. Store timestamps in UTC and convert them for display. An Australian publisher may work across Australian Eastern, Central, and Western time zones, with daylight saving affecting Sydney and Melbourne but not Perth. Scheduling based on a clearly configured site timezone prevents an article intended for Monday morning from appearing hours early or late.
Build Secure Authentication And Administration
Authentication begins with password storage. Passwords should be processed with a modern, adaptive password-hashing function such as Argon2id or bcrypt, with a unique salt generated by the library. The application should never log passwords, send them by email, or store reversible encryption as a substitute for hashing. Password reset tokens should be random, short-lived, single-use, and stored in a form that cannot reveal the original token if the database is exposed.
Sessions need similar care. Set secure, HTTP-only cookies, use an appropriate SameSite policy, rotate the session identifier after login, and expire inactive sessions. Administrative traffic should be served over HTTPS. A small CMS may have only a few staff accounts, but those accounts are valuable targets because they can alter every page and upload executable content if the system is poorly designed.
Every state-changing request should use protection against cross-site request forgery. Input validation should happen at the boundary of the application, while output encoding should happen when values are placed into HTML, URLs, JavaScript, or SQL. Parameterised queries prevent injection, but they do not make inserted HTML safe. Rich text must be sanitised with a carefully maintained allowlist of elements and attributes.
The Australian Privacy Act 1988 and its Australian Privacy Principles are relevant when a CMS stores user accounts, contact details, analytics identifiers, or contributor information. The Notifiable Data Breaches scheme also affects organisations covered by the legislation. A privacy-conscious design collects only necessary information, documents retention periods, restricts administrative access, and has a practical process for investigating and reporting serious data breaches.
Create A Predictable Public Interface
A public CMS should make its URLs stable, readable, and easy to operate. A route such as /articles/designing-a-cms communicates more than a numeric path and is easier to share. Slugs should be generated from titles but remain editable with care. If a slug changes, create a permanent redirect from the old path instead of silently breaking bookmarks and search results.
Templates should provide a consistent page structure: document metadata, a descriptive title, navigation, main content, and a footer. Semantic HTML improves accessibility and gives browsers, screen readers, and search engines useful information. Keyboard navigation, visible focus states, sensible heading order, and adequate colour contrast are inexpensive when considered from the beginning.
Images require their own content model. Store the original file outside the public document root when possible, generate controlled derivatives, and retain width, height, MIME type, and alternative text. Validate file signatures rather than trusting extensions. Uploads should receive generated names and should never be executed by the web server. This matters for a publication with contributors using different devices, including phones and laptops on Australian home networks.
Search can begin with a simple database query over titles, summaries, and body text. Add indexes to fields used for filtering and ordering, and inspect query plans before performance becomes a complaint. A full-text index can follow when the archive grows. Caching rendered pages or common queries is useful, though cache invalidation should be tied to publishing events rather than handled through guesswork.
Editorial accuracy also depends on source handling. If an article contains health or safety information, the CMS can offer fields for source names, review dates, and reference links; an editor discussing clinical symptoms might attach a clinical reference rather than presenting an unsupported claim. Such metadata is useful for trust, maintenance, and later review.
Test, Deploy, And Operate The System
Testing should reflect the system’s risks. Unit tests can cover slug generation, permissions, date conversion, and content sanitisation. Integration tests can create an article, submit it for review, publish it, and confirm that the public route displays the approved revision. Browser tests are valuable for login, image upload, and the editor workflow, where a small change can block the whole publishing process.
Backups need to be tested through restoration, not merely scheduled. Keep database backups, uploaded media, and configuration secrets in appropriate separate locations, with encryption and restricted access. Define how much recent work the organisation can afford to lose and how quickly the site must return after a failure. A nightly backup may be adequate for a low-volume archive, while a busy publication may need more frequent database snapshots.
Logging should help an operator answer what happened without recording sensitive material. Record failed logins, permission failures, publication events, deployment identifiers, and application errors. Centralised logs and uptime monitoring are useful when a small team operates the site outside business hours. Alerts should be selective; constant noise teaches people to ignore the monitoring system.
Deployment can remain straightforward. A staging environment should use representative but non-sensitive data, migrations should run in a controlled step, and a release should have a rollback procedure. Security updates for the operating system, runtime, framework, and third-party packages must be part of routine maintenance. The Australian Signals Directorate’s Essential Eight provides a useful security baseline for organisations that need a practical framework for hardening systems.
Compare Implementation Choices
The best technical choice depends on the publishing workload, the team’s skills, and the expected life of the project. A custom CMS gives close control over the data model and editorial workflow, while a mature platform supplies many features but brings its own update and extension obligations. A headless approach can serve mobile applications and multiple websites, although it introduces additional APIs, authentication paths, and operational complexity.
The following comparison focuses on a small Australian editorial operation rather than a large media company. Cost includes more than hosting: maintenance time, security work, upgrades, training, and the risk of being unable to change a system when requirements evolve.
| Approach | Strengths | Costs And Risks | Suitable Starting Point |
|---|---|---|---|
| Custom server-rendered CMS | Precise workflow, small attack surface, clear data ownership | Requires development, testing, security maintenance, and documentation | A technical publication with a defined model |
| Established CMS platform | Fast initial setup, mature extensions, familiar admin tools | Plugin conflicts, upgrade work, larger attack surface, vendor dependencies | A team needing common features quickly |
| Headless CMS | Flexible delivery to websites, apps, and other channels | API security, separate frontend work, more deployment components | Multiple channels with development resources |
| Static publishing system | Strong performance, simple hosting, low runtime exposure | More complex previews, forms, and frequent editorial changes | Stable archives and technically confident editors |
A custom system should remain modest after launch. Add features when a real editorial problem has been observed, not because a competing product offers them. Metrics such as publishing time, failed deployments, search success, and support requests reveal where investment is justified. This evidence-based approach keeps the codebase readable and prevents a simple publishing tool from becoming an accidental enterprise platform.
The finished system should be understandable to the next developer who opens it. Clear migrations, documented roles, predictable routes, tested backups, and restrained dependencies create more long-term value than an impressive feature list. From that foundation, the CMS can evolve carefully while retaining the qualities that made it useful in the first place.
