Hi everyone,

I am relatively new to Julia - and everytime I solve a problem, I find a new one 🙂

Currently, I want to create and name an environment where some pacakges are precomplied:  
CSV, DataFrames,Queryverse, Unitful, DifferentialEquations, JSON.  
I am setting up a web service through Rshiny, where ppl will upload some parameters, they will arrive a JSON to me I’ll run a script solving some differential equaltions through the shell and I’ll spit a CSV with the results which will then be read by RShiny to display plots.  
I am only in charge of the backend - The reason I need a precompiled environment is that otherwise everytime I run my code on the shell it recompiles the packages -  
I am new to Julia and would like to know if there is an easy way to create a named environment where I can keep this packages precompiled - If any one has some advice on this I’ll greatly appreciate it

Take care,

A
