Hardcoding vs Softcoding

John Spacey, updated on July 13, 2023

Hardcoding is the practice of writing source code that must be rewritten in order to change its behavior. In other words, hardcoded logic isn't configurable. Hardcoding is appropriate when it is reasonable to expect that a change would require the work of a programmer.

Softcoding accepts parameters or looks up values in a configuration file or database that alter the flow of computer logic. A user interface may be provided to allow users to update these values. Softcoding provides the ability for users to change the functioning of a system without a programmer. This may also be used to improve the general maintainability of code.

Tradeoffs

Well written code is typically both hardcoded and softcoded. In theory, softcoding is done to improve maintainability of code. However, if taken too far it becomes a mess of complex configuration files and execution code that is wimpy about implementing logic with roundabout approaches that reduce maintainability. Softcoding also has a tendency to shift errors from compile time to run time, making testing more time consuming and expensive.
