@ziftrshop/filter-expressions v1.1.0

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.
