Props API

As of 1.0.0-next.40 the props api has changed, read this guide to figure out how to change your code.

Add App Types

You will need to add a file called src/app.d.ts with the following contents:

/// <reference types="jellycommands/ambient" />

// See
interface Props {}

Change usage of props

Props changed from being an object with methods (get, set, and has), to a regular object.

- const db = props.get('db');
+ const db = props.db
- props.set('db', database);
+ props.db = database;

Change how props are typed

Props are now typed globally for ease of use, you can edit the Props interface in your src/app.d.ts to achieve this. No more importing types everywhere you use your props.

Accessing props in commands and events

We added the props object directly to command and event context to access it quicker:

export default command({
-   run({ client }) {
+   run({ props }) {
-       const db = client.props.get<DB>('db');
+       const db = props.db;

TS & JS Config

If you are using TypeScript you should have a tsconfig.json in your project, similiarly if you are using JavaScript you should have a jsconfig.json in your project. They should both look something like this:

    "compilerOptions": {
        "lib": ["ESNext"],
        "module": "ESNext",
        "target": "ESNext",
        "esModuleInterop": true,
        "forceConsistentCasingInFileNames": true,
        "moduleResolution": "node",
        "resolveJsonModule": true,
        "strict": true,
        "checkJs": true,
        "allowJs": true
    "include": ["./src/**/*.js", "./src/**/*.ts"]


Props previously threw an error when you tried to access soemthing that didn't exist, this is no longer the case.
