For a newer version supporting a more recent version of UI5, see https://github.com/neoprincie/ui5ts.
A simple adapter to develop SAPUI5 and OpenUI5 applications using TypeScript and ES2015 modules/classes
0.3.2 - Handle some UI5 API errors in the Docs, when method with names like getSomething has void as return type. It is being replaced by any now.
0.3.1 - Just fixed an error in this README instructions.
0.3.0 - Create definitions for more than one version of UI5 (just 1.46 and 1.48 for now). Published in https://github.com/lmcarreiro/ui5-typescript-definitions too. Be carefull, now that there is these definitions inside the package and I have plans to make these definitions better (normally replacing an any type with a more specific one), almost all new versions from now on may be a breaking change.
0.2.0 - Create my own UI5 definitions generator, because the available ones didn't fit my needs (you can still use another, just set it up in your tsconfig.json).
0.1.* - Generated exports files for all namespace sap.* objects, to make possible import these objects without creating a single <object>.d.ts for each imported object.
0.0.* - Just a draft.
It is very simple, make it work with only 4 steps:
- Install ui5ts, typescript and @types/jquery npm packages
- Add a reference to the "library" in your index.html
- Add the required TypeScript options in the tsconfig.json
- Change your
<class-name>.jsto a<class-name>.ts
Check this Master-Detail example app https://github.com/lmcarreiro/ui5-typescript-example that is already working with ui5+typescript.
npm install @types/jquery --save-dev
npm install typescript --save-dev
npm install ui5ts --save
Put a reference to the ui5ts.js script in your index.html file using a script tag <script src="node_modules/ui5ts/ui5ts.js" type="text/javascript"></script> between the sap-ui-core.js script tag and the sap.ui.getCore().attachInit() call:
...
<!-- Bootstrapping UI5 -->
<script id="sap-ui-bootstrap" src="https://openui5.hana.ondemand.com/resources/sap-ui-core.js" ... ></script>
+ <!-- Convert typescript generated modules/classes into ui5 modules/classes -->
+ <script type="text/javascript" src="node_modules/ui5ts/ui5ts.js"></script>
<script>
sap.ui.getCore().attachInit(function () { ... });
</script>
...- compilerOptions.module =
"amd" - compilerOptions.experimentalDecorators =
true(just to avoid typescript warning/error) - compilerOptions.baseUrl =
"./"(your project root, if you change this value, you need to change the paths too) - compilerOptions.paths =
{ ... }(your paths, relative to your baseUrl, check the example bellow) - files =
["node_modules/ui5ts/ui5ts.d.ts", "node_modules/ui5ts/ui5-types/1.48/sap.d.ts", "node_modules/ui5ts/ui5-types/1.48/jQuery.d.ts", ...]

});import UIComponent from "sap/ui/core/UIComponent";

export default class Component extends UIComponent
{
public static metadata: any = {

public init(): void {
// set the device model
this.setModel(models.createDeviceModel(), "device");

}
}- You need to decorate your class with
@UI5("your.full.namespace.ClassName"), this decorator parameter will be passed toBaseClass.extend("your.full.namespace.ClassName", { ... });call at runtime. - You need to export your class as default export.
- If your class has the ui5 metadata object, define it as
static - The paths in the
importstatements must be the same as it would be if you were usingsap.ui.define()function. The TypeScript compiler will generate an AMD module with adefine()call with these paths, and thedefine()function that ui5ts overrides will call the realsap.ui.define()function. This is the way that ui5ts works. - If
your/app/namespace/is/too/big, you don't need to have all this levels of directories in your physical project structure, you can create a virtual mapping using thetsconfig.jsonconfiguration optionpaths(see it in the common problems bellow).
Problem: Doesn't find the @UI5 decorator:
...
// error TS2304: Cannot find name 'UI5'.
@UI5("your.full.namespace.ClassName")
export default class Component extends UIComponent {
...Solution: Make sure you have the ui5ts.d.ts referenced in your tsconfig.json
...
"files": [
...,
+ "node_modules/ui5ts/ui5ts.d.ts"
],
...Problem: Doesn't find your own *.ts class:
...
// error TS2307: Cannot find module 'your/app/namespace/folder/ClassName'.
import ClassName from "your/app/namespace/folder/ClassName";
...Solution: Make sure you have the path of your namespace root in the tsconfig.json and if it match with your application startup in the index.html
...
"compilerOptions": {
...
"baseUrl": "./",
"paths": {
...
+ "your/app/namespace/*": [ "./src/*" ]
}

sap.ui.getCore().attachInit(function () {
sap.ui.require(["sap/m/Shell", "sap/ui/core/ComponentContainer"], function (Shell, ComponentContainer) {
new Shell({
app: new ComponentContainer({
height : "100%",
+ name : "your.app.namespace"
})
}).placeAt("content");
});
});
...Problem: Doesn't find your own *.js class:
...
// error TS2307: Cannot find module 'your/app/namespace/folder/ClassName'.
import ClassName from "your/app/namespace/folder/ClassName";
...Solution: Create a corresponding *.d.ts of your *.js class or forget about it. You can live with this error and the app will still work. Even if you allow the TypeScript compiler to accept *.js modules, it will not recognize it as a AMD module, since you declare it using sap.ui.define() instead of define().
Problem: Doesn't find a class in sap.* namespace:
...
// error TS2307: Cannot find module 'sap/ui/core/UIComponent'.
import UIComponent from "sap/ui/core/UIComponent";
...Solution: Make sure you have mapped the ui5ts exports folder in your paths of the tsconfig.json:
...
"compilerOptions": {
...
"baseUrl": "./",
"paths": {
...
+ "sap/*": [ "./node_modules/ui5ts/exports/sap/*" ]
}
