Apostrophe Redis Cache

GitHub Workflow Status (branch)

This module enhances the core caching module, @apostrophecms/cache, to use Redis rather than MongoDB. This module does not set up the actual Redis store, but instead allows Apostrophe to access an existing Redis store through the standard Apostrophe caching API and an internal Redis client.

All normal Apostrophe cache API features are maintained in addition to the Redis-specific features described below.


To install the module, use the command line to run this command in an Apostrophe project's root directory:

npm install @apostrophecms/cache-redis


Configure the Redis cache module in the app.js file:

  shortName: 'my-project',
  modules: {
    '@apostrophecms/cache-redis': {}

Configuring Redis options

All options for this module should be applied to @apostrophecms/cache in project code. This module simply "improves" that core module (updates its features). The main caching module still does all the work.

Configure the underlying Redis client by adding a configuration object on the cache module's redis option.

// modules/@apostrophecms/cache/index.js
module.exports = {
  options: {
    redis: {
      url: 'redis://alice:foobared@awesome.redis.server:6380'

By default, the client will look for a Redis server running on localhost port 6379. See all the client configuration options on the Node-Redis documentation.

Note that this module uses the 4.x version of Node-Redis, which changed its configuration options from earlier major versions.

Cache keys

The Apostrophe cache get and set methods take two arguments that are used for individual cache item keys:

Argument Description
namespace A namespace for related data. Apostrophe core often uses the active module's name for the namespace, e.g., @apostrophecms/oembed.
key The unique cache item key within a namespace.
await apos.cache.get(namespace, key)
await apos.cache.set(namespace, key, value)


const fetch = node
// modules/api-connect/index.js
module.exports = {
  apiRoutes(self) {
    return {
      get: {
        // GET /api/v1/api-connect/set-cache-info
        async setCacheInfo(req) {
          const info = await myApiClient.get({ latest: true });

          // 👇 This status will be "OK" if successful. This is due to the Redis
          // API, not a common Apostrophe pattern.
          const status = await self.apos.cache.set('api-connect', 'latest', info);

          return { status };
        // GET /api/v1/api-connect/get-cache-info
        async getCacheInfo(req) {
          // 👇 This will return the stored information or `undefined` if not
          // set.
          const latest = await self.apos.cache.get('api-connect', 'latest');

          return { latest };

Using the prefix for multiple sites

By default, this module applies a prefix to cache keys in the store. This prefix is the shortname of the website, which automatically separates cache items if multiple Apostrophe sites share the same Redis store.

To disable the cache key prefix, set the cache module's prefix option to false.

// modules/@apostrophecms/cache/index.js
module.exports = {
  options: {
    prefix: false

To customize the prefix, set the prefix option to the desired string value.

// modules/@apostrophecms/cache/index.js
module.exports = {
  options: {
    prefix: 'project-alpha'
