Techniques for utilizing an expression language in service configuration files

A device for processing a configuration file having a JavaScript Object Notation (JSON) format, comprising:

• a memory storing one or more parameters or instructions for providing a platform engine and for storing an in-memory representation of the configuration file for executing one or more contexts of the platform engine;
• and
• at least one processor coupled to the memory, wherein the at least one processor is configured to:
• determine one or more static data values defined in the configuration file based on the JSON format;
• detect one or more expressions, defined according to an expression language, in the configuration file based on the JSON format;
• interpret, via the platform engine and based on the expression language, the one or more expressions, wherein interpreting the one or more expressions comprises interpreting a function in at least two name value pairs, wherein a name of a first one of the at least two name value pairs includes a string reserved for indicating functions and a value of the first one of the at least two name value pairs indicates a function name of the function, and wherein a name of a second one of the at least two name value pairs includes a string reserved for indicating a list of one or more arguments for the function in a value of the second one of the at least two name value pairs, and wherein the value of the second one of the at least two name value pairs indicates the list of one or more arguments;
• store, in the memory and based on interpreting the one or more expressions, the one or more expressions and the one or more static data values as the in-memory representation of the configuration file;
• and
• execute, by the platform engine and based on the in-memory representation of the configuration file, an instance of a service for resolving one or more values related to the one or more expressions and using the one or more static data values and the one or more values related to the one or more expressions, as resolved in the representation of the configuration file, to configure the platform engine for executing the service.

A non-transitory computer-readable medium, comprising code executable by one or more processors for processing a configuration file having a JavaScript Object Notation (JSON) format, the code comprising code for:

• determining one or more static data values defined in the configuration file based on the JSON format;
• detecting one or more expressions, defined according to an expression language, in the configuration file based on the JSON format;
• interpreting, via a platform engine and based on the expression language, the one or more expressions, wherein interpreting the one or more expressions comprises interpreting a function in at least two name value pairs, wherein a name of a first one of the at least two name value pairs includes a string reserved for indicating functions and a value of the first one of the at least two name value pairs indicates a function name of the function, and wherein a name of a second one of the at least two name value pairs includes a string reserved for indicating a list of one or more arguments for the function in a value of the second one of the at least two name value pairs, and wherein the value of the second one of the at least two name value pairs indicates the list of one or more arguments;
• storing, in a memory and based on interpreting the one or more expressions, the one or more expressions and the one or more static data values as a representation of the configuration file;
• and
• executing, by the platform engine and based on the representation of the configuration file, an instance of a service for resolving one or more values related to the one or more expressions and using the one or more static data values and the one or more values related to the one or more expressions, as resolved in the representation of the configuration file, to configure the platform engine for executing the service.
