Expression Parser
A tiny Node.js expression parser library designed to be embedded in other ZiftrShop projects.
It contains no external dependencies at runtime and compiles and compresses to ~3kb.
There is an emphasizes simplicity over performance since expressions are not called often and do not need to be fast.
Syntax
Expressions support the following opperators: ==, !=, >, <, >=, <=.
You can sepperate expression using AND and OR and also group expressions with ( and ). The order of opperations when mixing AND/OR is undefined behavior so best practice is to use parenthesis for disambiguation.
Installing
npm install --save @ziftrshop/filter-expressions
Running Tests
npm run test
Packaging
npm run dist
This will create a file dist/zs-expression-lib.js that is suitable for user in browsers or to copy and paste (embed) in a Node.js. It will assign the library to a variable called ZiftrshopExpressions.
