Allow to specify tls options for Redis

[arnaud-thorel-of]

Hi everyone,

During my tests with sourcebot, I figured that it doesn't work with external redis using tls with SNI validation because of the construction of ioredis connector :

sourcebot/packages/backend/src/index.ts

Line 42 in 5c4b0ce

const redis = new Redis(env.REDIS_URL, {

Is it possible de add in new versions the ability to override tls options ?

In my case I just need the servername options, but maybe other has to configure other options

tls: { servername: *SERVER_NAME* }

List of tls options : https://nodejs.org/api/tls.html

Maybe you can allow us to override the entire tls, or map each tls option with a VAR_ENV

REDIS_TLS={ servername: myServerName}
REDIS_TLS_SERVERNAME=myServerName

Thx a lot for your responses

env.server.ts

 REDIS_TLS_OPTS: z.string().optional().transform((val) => {
 if (!val) return undefined;
 try {
 return JSON.parse(val) as Record<string, unknown>;
 } catch {
 throw new Error(`REDIS_TLS_OPTS is not valid JSON: ${val}`);
 }
 }),

backend/index.ts

const redis = new Redis(env.REDIS_URL, {
 maxRetriesPerRequest: null,
 ...(env.REDIS_TLS_OPTS ? { tls: env.REDIS_TLS_OPTS } : {}),
});
