Install [↑]
Execute the following command from your project folder, where your
package.json file is stored:
npm install --save @egomobile/http-serverIf you want to lookup types, also install the Node Types:
npm install --save-dev @types/nodeUsage [↑]
Quick example [↑]
import createServer, { buffer, params, query } from "@egomobile/http-server";
async function main() {
const app = createServer();
// POST request for / route
// that uses the middleware buffer(), which loads the
// whole request body with a limit of 128 MB by default
// and writes the data to 'body' prop of 'request' object
// as Buffer
app.post("/", [buffer()], async (request, response) => {
const name: string = request.body!.toString("utf8");
response.write("Hello: " + name);
// no response.end() is required here
});
// parameters require a special path validator here
// s. https://github.com/lukeed/regexparam
// for more information about the string format
app.get(params("/foo/:bar/baz"), async (request, response) => {
response.write("BAR: " + request.params!.bar);
});
// parse query parameters from URL
// and write them to 'query' prop of 'request' object
app.get("/foo", [query()], async (request, response) => {
// request.query => https://nodejs.org/api/url.html#class-urlsearchparams
response.write(" BAR: " + request.query!.get("bar"));
response.write(" BAZ: " + request.query!.get("baz"));
});
await app.listen();
console.log(`Server now running on port ${app.port} ...`);
}
main().catch(console.error);Middlewares [↑]
To enhance the functionality of your handlers, you can setup global or route specific middlewares.
For more details, have a look at the wiki page.
Controllers [↑]
The module provides tools, like decorators, functions and classes, that helps to setup routes and their behavior on a quite simple and high level.
Have a look at the wiki page for detailed information.
Error handling [↑]
import createServer from "@egomobile/http-server";
async function main() {
// ...
// custom error handler
app.setErrorHandler(async (error, request, response) => {
const errorMessage = Buffer.from("SERVER ERROR: " + String(error), "utf8");
if (!response.headersSend) {
response.writeHead(400, {
"Content-Length": String(errorMessage.length),
});
}
response.write(errorMessage);
response.end();
});
// custom 404 handler
app.setNotFoundHandler(async (request, response) => {
const notFoundMessage = Buffer.from(`${request.url} not found!`, "utf8");
if (!response.headersSend) {
response.writeHead(404, {
"Content-Length": String(notFoundMessage.length),
});
}
response.write(notFoundMessage);
response.end();
});
app.get("/", async (request, response) => {
throw new Error("Something went wrong!");
});
// ...
}
main().catch(console.error);Pretty error pages [↑]
A nice example is, to use Youch! by Poppinss.
It prints pretty error pages in the browser:
import createServer, { prettyErrors } from "@egomobile/http-server";
import youch from "youch";
async function main() {
// ...
app.setErrorHandler(async (error, request, response) => {
const html = Buffer.from(await new youch(error, request).toHTML(), "utf8");
if (!response.headersSent) {
response.writeHead(500, {
"Content-Type": "text/html; charset=UTF-8",
"Content-Length": String(html.length),
});
}
response.end(html);
});
app.get("/", async (request, response) => {
throw new Error("Oops! Something went wrong!");
});
// ...
}
main().catch(console.error);A possible result could be:
Testing [↑]
With decorators @Describe() and @It(), you can write automatic (unit-)tests, realized by any framework you want.
This example shows, how to implement tests with SuperTest (if you want to see a more detailed description of this feature, you can visit the wiki page):
Controller [↑]
import {
Controller,
ControllerBase,
Describe,
GET,
IHttpRequest,
IHttpResponse,
It,
} from "@egomobile/http-server";
@Controller()
@Describe("My controller")
export default class MyController extends ControllerBase {
@GET("/foo/:bar")
@It(
"should return '{{body}}' in body with status {{status}} when submitting parameter {{parameter:bar}}",
{
expectations: {
body: "BUZZ",
status: 202,
},
parameters: {
bar: "buzz",
},
}
)
async index(request: IHttpRequest, response: IHttpResponse) {
response.writeHead(202);
response.write(request.params!.bar.toUpperCase());
}
}Initialization [↑]
import assert from "assert";
import supertest from "supertest";
import { createServer } from "@egomobile/http-server";
const app = createServer();
// event, that is executed, if a test is requested
app.on("test", async (context) => {
const {
body,
description,
escapedRoute,
expectations,
group,
headers,
httpMethod,
server,
} = context;
try {
process.stdout.write(`Running test [${group}] '${description}' ... `);
// prepare request ...
// HTTP method ...
let request = supertest(server)[httpMethod](escapedRoute);
// request headers ...
for (const [headerName, headerValue] of Object.entries(headers)) {
request = request.set(headerName, headerValue);
}
// send it
const response = await request.send(body);
assert.strictEqual(response.statusCode, expectations.status);
// maybe some more code checking headers and
// body data from `expectations` ...
process.stdout.write(`✅\n`);
} catch (error) {
process.stdout.write(`❌: ${error}\n`);
}
});
// run tests
await app.test();
// alternative:
//
// if you set `EGO_RUN_SETUP` to a truthy value like `1`
// the server does not start listening, instead it simply
// runs `app.test()`
//
// await app.listen();Benchmarks [↑]
