👋 Hey All, just starting to piece together a larger stack for the first time and starting to deal with

Output<string>

types. I'm dealing with a MongoDB URI, db name, and an associated username/password. I have all 4 of these as outputs, and i am trying to form them into a proper MongoDB connection string. This involves taking the URI in the format

<mongodb+srv://mycluster.randomchars.mongodb.net>

and inserting the username/password to form this format:

mongodb+srv://<username>:<password>@mycluster.randomchars.mongodb.net/<dbName>

. The problem I have is that I need to do some sort of replace in order to retain the

mycluster.randomchars

section of the URI - this means that

pulumi.interpolate

is not sufficient for my use-case. Any suggestions where I can go from here? Just keep them separate and form them properly in the application?

use an

apply

- once you’re inside the

apply

you can manipulate the string as you would any other string

The uri already has the random section. However, I need to insert the

username:password@

section after the

mongodb+srv://

section.

Here's my code to do similar for SQL Server... Given a variable

sqlServerOutput

which is of type:

Output.Tuple<string, string, string>  // aka
Output<(string, string, string)>

Using

.Apply

looks like:

// Server=tcp:{server-name}.<http://database.windows.net|database.windows.net>,1433;Initial Catalog={db-name};Persist Security Info=False;User ID={login-name};Password={login-password};MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;
        return sqlServerOutput.Apply(t =>
        {
            (string server, string loginId, string loginPassword) = t;
            return sqlDatabase.Name.Apply(finalDbName =>
                $"Server=tcp:{server}.<http://database.windows.net|database.windows.net>,1433;Initial Catalog={finalDbName};Persist Security Info=False;User ID={loginId};Password={loginPassword};MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;"
            );
        });

Thanks. I think I got it working how I need in my case.

const mongoDbUri = pulumi
        .all([db.uri, db.user, db.password, db.name])
        .apply(([uri, user, password, name]) => {
          const [prefix, suffix] = uri.split('//')
          return `${prefix}//${user}:${password}@${suffix}/${name}`
        })

language primitives ftw!
