Initialize a cache once during server init?

[jaidetree]

Got a posts.server.ts that has an API for fetching and caching posts from a source.

Would like to have this run asynchronously once when the remix server starts so content is pre-cached. Originally, tried to create a standalone script to run during build but this proved impractical as a lot of code depends on the aliases that the tsconfig specifies that are not supported by a regular node js script file.

Where would it live? Was originally thinking it could be placed in posts.server.ts or entry.server.ts but both those seem to run every request.

Is there a good place to do something like that?

The reason module-level variables are reinitialized on every request is due to <LiveReload/>

In development you should store your cache on the global object to survive the purge.

See the Jokes tutorial where it discusses how to maintain the database connection.

Thanks! That's where I landed on using a global.cacheInitialized:

if (!global.cacheInitialized) {
  // cache content

  global.cacheInitialized = true
}
