simple-placeholder-replacer v1.1.0

simple-placeholder-replacer

A library to replace placeholders in a json/string object. You have to use double curly brackets {{placeholderKey}} to identify the placeholder and proivide a map with pairs of key / value where the key is the name of the placeholder (case doesn't matter) and value is the replacement value for that placeholder. The library can also handle date / date time placeholders that are {{now}} or {{today}} (again case doesn't matter) and that can be configured with the following options :

• a number of units to add / subtract to the system date / time e.g. {{today+1d}} -> will cause the library to replace this tag with the system date + one day Note that the unit is not mandatory, days will be the unit by default for {{today}} and hours for {{now}} Available units for {{today}} are :

    - d / D : days
    - m / M : months
    - y / Y : years
    - w / W : weeks
    

  Available units for {{now}} are :

    - h / H : hours
    - m / M : minutes
    - s / S : seconds
    

• the desired output format for the date / date time e.g. {{now=HH:MM:SS}} -> will output the current time Note that the format must be compatible with formats recognized by the moment js library Default formats are :

    - {{today}} -> YYYY-MM-DD
    - {{now}}   -> YYYY-MM-DDTHH:MM:SS
