@tjc-group/odata-v2-server v0.0.71

This is a downgrade from odata-v4-server.

We need to provide OData V2 metadata and response payload Please be advised that this is in alfa status.

• Added method parameter decorators:

  • @odata.path: OData resource path parsing tree
  • @odata.navstep: Current navigation step

• Now controller methods are called with controller instance (not controller class descriptor)

• $batch requests implemented, though no callbacks yet for start and end of changsets

• OData V2 payload can be switched off via ODataProcessorOptions class

Please see below the original README of JayStack odata-v4-server

Example Northwind server

export class ProductsController extends ODataController{
    @odata.GET
    find(@odata.filter filter:ODataQuery){
        if (filter) return products.filter(createFilter(filter));
        return products;
    }

    @odata.GET
    findOne(@odata.key key:string){
        return products.filter(product => product._id == key)[0];
    }

    @odata.POST
    insert(@odata.body product:any){
        product._id = new ObjectID().toString();
        products.push(product);
        return product;
    }

    @odata.PATCH
    update(@odata.key key:string, @odata.body delta:any){
        let product = products.filter(product => product._id == key)[0];
        for (let prop in delta){
            product[prop] = delta[prop];
        }
    }

    @odata.DELETE
    remove(@odata.key key:string){
        products.splice(products.indexOf(products.filter(product => product._id == key)[0]), 1);
    }
}

export class CategoriesController extends ODataController{
    @odata.GET
    find(@odata.filter filter:ODataQuery){
        if (filter) return categories.filter(createFilter(filter));
        return categories;
    }

    @odata.GET
    findOne(@odata.key key:string){
        return categories.filter(category => category._id == key)[0];
    }

    @odata.POST
    insert(@odata.body category:any){
        category._id = new ObjectID().toString();
        categories.push(category);
        return category;
    }

    @odata.PATCH
    update(@odata.key key:string, @odata.body delta:any){
        let category = categories.filter(category => category._id == key)[0];
        for (let prop in delta){
            category[prop] = delta[prop];
        }
    }

    @odata.DELETE
    remove(@odata.key key:string){
        categories.splice(categories.indexOf(categories.filter(category => category._id == key)[0]), 1);
    }
}

@odata.cors
@odata.controller(ProductsController, true)
@odata.controller(CategoriesController, true)
