10/19/2023, 6:35 AMHello everybody. A bit of a weird question here. I was wondering how I would edit the source code of Growthbook and create a new image of it? Long story short, the way growthbook accepts a MONGODB_URI does not really work for my use case, and I would prefer to edit the source code to accept username, password, and endpoint, and then growthbook builds the URI. I have tried editing the source code and building a new image, but it doesn't seem to work properly and I'm not really sure why. Any help is appreciated. Thanks :)

you could also open a pull request with the changes to support another way of connecting to MongoDB

10/19/2023, 7:52 AMI will look into the contributing guide. As far as I've seen I need to send growthbook a complete MONGODB_URI as an ENV variable. This poses issues when using AWS CDK. I'd like to be able to send the parts that make up the URI, and have growthbook build it. But I will look into the contributing guide and see if I can figure out a solution. Thanks 🙂

10/19/2023, 2:18 PM@elegant-king-24193 This is my proposal based on your suggestion:
https://github.com/growthbook/growthbook/compare/main...yepher:growthbook:feature/alt_mongo_credentials
Copy code
let MONGODB_URI = process.env.MONGODB_URI;
if (!MONGODB_URI) {
// Check for alternate mongo db environment variables
if (
process.env.MONGO_DB_USERNAME &&
process.env.MONGO_DB_PASSWORD &&
process.env.MONGO_DB_HOSTNAME
) {
MONGODB_URI = `mongodb://${process.env.MONGO_DB_USERNAME}:${process.env.MONGO_DB_PASSWORD}@${process.env.MONGO_DB_HOSTNAME}/growthbook`;
// Add extra args if they exist
if (process.env.MONGO_DB_EXTRA_ARGS) {
MONGODB_URI += `?${process.env.MONGO_DB_EXTRA_ARGS}`;
}
}
