magic-odata

Magical OData client generation for typescript. No more string. No more any!

Install

npm i magic-odata-code-gen --save-dev; npm i magic-odata-client;

• magic-odata-code-gen is a dev dependency required to generate a client at compile time
  • This tool is small and we recommend installing it locally per project in order to avoid versioning issues
• magic-odata-client is a dependency of your application. The generated code will use this package

Generate

node node_modules/magic-odata-code-gen/dist/index.js --metadataUrl "https://raw.githubusercontent.com/ShaneGH/magic-odata/main/docs/sampleOdataMetadata.xml"

Use

// import a generated client
import { ODataClient } from "./odataClient.js"

// create a client instance
const oDataClient = new ODataClient({
    // inject a basic Http client
    request: (input, init) => fetch(input, init),

    // add a root URI
    uriRoot: "https://my.odata.server/odata"
})

// use the client!
const popularBlogPosts = oDataClient.BlogPosts
    // Use object deconstruction to choose query tools
    .withQuery((blogPost, {
        $orderby: {orderBy}, 
        $skip, 
        $top
    }) => [ 
        // Combine query tools and fluent operations to build a query
        blogPost.Comments.$count.gt(100).or(blogPost.Likes.gt(100)),
        orderBy(blogPost.Name),
        $skip(0),
        $top(10)
    ])
    .get();

Why?

Write safe, statically typed odata queries in typescript. No more string. No more any!

• Cut down on runtime errors
• Explore OData API possibilities in your IDE
• Runs in the browser or in node
• No prod dependencies. Small bundle size
  • Generated executable code is tiny. Almost all generated code is type information
  • magic-odata-client minifies and compresses to ~10KB
• Optional angular mode, for the angular HttpClient
