Typed Client Server API

Create REST-ish API server and client implementation without mistakes.

• One file with definition for server and client.
• IDE will tell you what is necessary implement and what it returns.
• Error before compile on client and server code.

API definition

Define types to file for client and server in one file api.d.ts.

import { APIDefinition, Endpoint } from "typed-client-server-api";

export type API = APIDefinition<{
    addPhoto: Endpoint<Photo, string>,
    getPhoto: Endpoint<{ id: string }, Photo>,
    updatePhoto: Endpoint<Photo, void>,
    removePhoto: Endpoint<{ id: string }, void>,
}>;

Browser

import { setServerUrl, getAPIFrontend, setHeaders } from "typed-client-server-api";
import { API } from "../api.d.ts";

setServerUrl(process.env.NODE_ENV === "development" ? "http://localhost:8080" : "");

export const api = getAPIFrontend<API>();

// usage
const [ photo, error, status ]  = await api.addPhoto({ data });

React

import { setServerUrl, getUseAPIFrontend, setHeaders } from "typed-client-server-api/hooks";
import { API } from "../api.d.ts";

setServerUrl(process.env.NODE_ENV === "development" ? "http://localhost:8080" : "");

export const useApi = getUseAPIFrontend<API>();

// usage
function App() {
    const [ result, error, isLoading, status, reload ] = useApi.getPhoto({ id });
    ...

Node

import { setAPIBackend } from "typed-client-server-api";
import express from "express";

import { API } from "../api.d.ts";

const app = express();

app.use(express.json());

setAPIBackend<API>(app, {
    async addPhoto({ data }, req, res) {
        // check permission with `req`
        // add photo and return string
    },
    async getPhoto({ id }) {
        // return photo
    },
    // other methods
});

app.listen(PORT, () => console.log(`Server is running at http://localhost:${PORT}.`));
