OData Filter Core (WebAssembly)
Installation
See INSTALL.md for full instructions.
Usage
Package Installation
npm i @odata-filter/core-wasm --saveBasic Example
Note: The output of the 'parse' function differs from the TypeScript version as union types are not supported in AssemblyScript. The 'format' property indicates the original token type, and the 'raw' property contains the original token string. The 'stringValue', 'intValue', 'floatValue', 'boolValue', and 'arrayValue' properties are used to store the parsed value based on the token type.
(async () => {
// AssemblyScript WebAssembly modules return a Promise that resolves to the module's exports when imported.
const { tokenize, parse } = await import('@odata-filter/core-wasm');
const tokens = tokenize("country/name eq 'US' and age gte 21");
parse(tokens);
