how to set REST path for gcloud api in vibe.d?

That code isn't the cause of your issue (its fine, no CTFE
needed).
We would need see more of your code surrounding:
auto uri = environment.get("MONGODB_URI");
MongoClient conn = connectMongoDB(uri);
MongoDatabase eqpdb = conn.getDatabase("MbEqpHeroku");
here is the code:
Camera[] showData(){
auto uri = environment.get("MONGODB_URI");
MongoClient conn = connectMongoDB(uri);
MongoDatabase eqpdb = conn.getDatabase("MbEqpHeroku");
MongoCollection cameras = eqpdb["cameras"];
Camera[] cs;

the "MONGODB_URI" showed above already put into heroku's app

is to extract the value which is to use for app to establish
mongodb connection.

That part of the code is probably fine.
Basically you have to be careful that:
auto uri = environment.get("MONGODB_URI");
Isn't being executed during compilation.
Stuff that typically cause this is anything that initializes a
variable.
Globals:
shared Foo foo = Foo(...);
Class fields:
class Foo {
Bar bar = Bar(...);
}
yes, then should be this?
struct Camera{
@name("_id") BsonObjectID id; // represented as "_id" in the

string brand;
string model;
}

In any case, the .strip above would not be eliminating empty lines; you need to filter them out e.g. with byLine.filter!(line => !line.empty) Aside: Instead of copying the lines with .idup explicitly, there is .byLineCopy that already does that.
