Content Server

Serves content tree structures very quickly.

Concept

A Server written in GoLang to mix and resolve content from different content sources, e.g. CMS, Blog, Shop and many other more. The server provides a simple to use API for non blocking content repository updates, to resolve site content by an URI or to get deep-linking multilingual URIs for a given contentID.

It's up to you how you use it and which data you want to export to the server. Our intention was to write a fast and cache hazzle-free content server to mix different content sources.

Overview

Export Data

All you have to do is to provide a tree of content nodes as a JSON encoded RepoNode.

Attribute	Type	Usage
Id	string	unique id to identify the node
MimeType	string	mime-type of the node, e.g. text/html, image/png, ...
LinkId	string	(symbolic) link/alias to another node
Groups	[]string	access control
URI	string	URI
Name	string	name
Hidden	bool	hide in menu
DestinationId	string	alias / symlink handling
Data	map[string]interface{}	payload data
Nodes	map[string]*RepoNode	child nodes
Index	[]string	contains the order of of nodes

Tips

• If you do not want to build a multi-market website define a generic market, e.g. call it universe
• keep it lean and do not export content which should not be accessible at all, e.g. you are working on a super secret fancy new category of your website
• Hidden nodes can be resolved by their uri, but are hidden on nodes
• To avoid duplicate content provide a DestinationId ( = ContentId of the node you want to reference) instead of URIs

Request Data

There is a PHP Proxy implementation for foomo in Foomo.ContentServer. Feel free to use it or to implement your own proxy in the language you love. The API should be easily to implement in every other framework and language, too.

Usage:
  contentserver [command]

Available Commands:
  completion  Generate the autocompletion script for the specified shell

      --log-format string   log format (default "json")
      --log-level string    log level (default "info")

Use "contentserver [command] --help" for more information about a command.

Storage Backends

The content server supports pluggable storage backends for persisting repository snapshots.

Filesystem (Default)

By default, the server stores snapshots on the local filesystem:

contentserver http --history-dir /var/lib/contentserver http://example.com/repo.json

Blob Storage (Cloud)

For cloud deployments, blob storage supports multiple providers via URL schemes:

Google Cloud Storage

contentserver http \
  --storage-type blob \
  --storage-blob-bucket gs://my-bucket \
  --storage-blob-prefix contentserver/snapshots/ \
  http://example.com/repo.json

Uses Application Default Credentials (ADC) for authentication.

AWS S3

contentserver http \
  --storage-type blob \
  --storage-blob-bucket "s3://my-bucket?region=us-east-1" \
  --storage-blob-prefix contentserver/snapshots/ \
  http://example.com/repo.json

Uses AWS SDK v2 default credential chain (environment variables, shared credentials file, IAM role).

Azure Blob Storage

contentserver http \
  --storage-type blob \
  --storage-blob-bucket azblob://my-container \
  --storage-blob-prefix contentserver/snapshots/ \
  http://example.com/repo.json

Uses Azure SDK default credential chain (environment variables, managed identity).

Environment Variables

Variable	Description
CONTENT_SERVER_STORAGE_TYPE	Storage type: filesystem (default) or blob
CONTENT_SERVER_STORAGE_BLOB_BUCKET	Blob storage URL with scheme (gs://, s3://, azblob://)
CONTENT_SERVER_STORAGE_BLOB_PREFIX	Object key prefix

See gocloud.dev/blob for detailed authentication configuration.
