CDS Uppercase Plugin

This plugin for the SAP Cloud Application Programming Model (CAP) automatically converts string attributes to uppercase. The uppercase logic is applied based on annotations either on the entire entity or specific attributes.

Features

- Automatically converts all string attributes to uppercase for entities annotated with @cds.uppercase.
- Converts specific string attributes to uppercase when annotated with @cds.uppercase.

Installation

To install the plugin, add it to your CAP project.

``sh npm install @neoimpulse/cap-js-uppercase`

`Usage`

1. Annotate Your Model

Add the @cds.uppercase annotation to your entities or specific attributes that should be converted to uppercase.

`plaintext namespace my.bookshop;

entity Books { key ID : Integer; title : String @cds.uppercase; author : String @cds.uppercase; }

entity Authors @cds.uppercase { key ID : Integer; name : String; }`

`How It Works`

The plugin scans all services and entities for the @cds.uppercase annotation. If an entity or its attributes are annotated, the plugin will automatically convert string attributes to uppercase before CREATE, UPDATE, and PATCH operations.

`javascript const cds = require("@sap/cds");

cds.once("served", () => { for (let srv of cds.services) { if (!(srv instanceof cds.ApplicationService)) continue; for (let entity of srv.entities) { if (entity["@cds.uppercase"]) { srv.before(["CREATE", "UPDATE", "PATCH"], entity, (req) => { for (const key in req.data) { if ( req.data[key] && req.data[key] !== null && typeof req.data[key] === "string" && req.data[key] !== "" ) { req.data[key] = req.data[key].toUpperCase(); } } }); } else { for (const key in entity.elements) { const element = entity.elements[key]; if (element.type === "cds.String" && element["@cds.uppercase"]) { srv.before(["CREATE", "UPDATE", "PATCH"], entity, (req) => { if (req.data[key] && typeof req.data[key] === "string" && req.data[key] !== "") { req.data[key] = req.data[key].toUpperCase(); } }); } } } } } });``

Usage

1. Annotate Your Model

Add the @cds.uppercase annotation to your entities or specific attributes that should be converted to uppercase.

plaintext
    namespace my.bookshop;

    entity Books {
        key ID : Integer;
        title  : String @cds.uppercase;
        author : String @cds.uppercase;
    }

    entity Authors @cds.uppercase {
        key ID : Integer;
        name  : String;
    }

How It Works

The plugin scans all services and entities for the @cds.uppercase

 annotation. If an entity or its attributes are annotated, the plugin will automatically convert string attributes to uppercase before

CREATE, UPDATE, and PATCH operations.

javascript
const cds = require("@sap/cds");

cds.once("served", () => {
    for (let srv of cds.services) {
        if (!(srv instanceof cds.ApplicationService)) continue;
        for (let entity of srv.entities) {
            if (entity["@cds.uppercase"]) {
                srv.before(["CREATE", "UPDATE", "PATCH"], entity, (req) => {
                    for (const key in req.data) {
                        if (
                            req.data[key] &&
                            req.data[key] !== null &&
                            typeof req.data[key] === "string" &&
                            req.data[key] !== ""
                        ) {
                            req.data[key] = req.data[key].toUpperCase();
                        }
                    }
                });
            } else {
                for (const key in entity.elements) {
                    const element = entity.elements[key];
                    if (element.type === "cds.String" && element["@cds.uppercase"]) {
                        srv.before(["CREATE", "UPDATE", "PATCH"], entity, (req) => {
                            if (req.data[key] && typeof req.data[key] === "string" && req.data[key] !== "") {
                                req.data[key] = req.data[key].toUpperCase();
                            }
                        });
                    }
                }
            }
        }
    }
