Increasing max body size

[JUNIORCO]

Is there a way to increase the max body size? We used to do the following:

const app = express();

app.use(bodyParser.json({ limit: "10mb" }));
app.use(express.json({ limit: "10mb" }));
app.use(express.urlencoded({ limit: "10mb", extended: true }));

We have it ported over to this library like this:

export const customEndpointFactory = new EndpointsFactory({
  resultHandler: customResultHandler,
  config: serverConfig,
})
  .addExpressMiddleware(bodyParser.json({ limit: '10mb' }))
  .addExpressMiddleware(express.json({ limit: '10mb' }))
  .addExpressMiddleware(express.urlencoded({ limit: '10mb', extended: true }))

But I don't think this is actually working (if the payload is too big I'm getting a 400 error).

Hello @JUNIORCO ,

first of all I have to mention that you can supply the JSON parser via config option jsonParser.

createConfig({
  server: {
    jsonParser: express.json({ limit: "10mb" }),
    // ...
  }
})

addExpressMiddleware might not suit here since it's being executed after parsing the body.

However, since you're also using other parsers (.urlencoded), I'd recommend going with .attachRouting() approach instead of createServer().

Thus, you can keep your original app initialization with all those limit adjustments.
