AzFunc 'context' object

Hi Yves

I haven’t find any sample that show a usage of the Azure Functions “context” object. This one is passed through the function as arg when you create a new HTTP Trigger Function : module.exports = function (context, req) and allow you to .log() information, very useful.

Could you tell me how could I get this object within the context of using your library please ? Many thanks 😃

Kind Regards

Olivier

FWIW this seems to have worked:

const { Writable } = require('stream');

app.use((req, res, next) => {
  const myStream = new Writable({
    write(chunk, encoding, callback) {
      req.context.log(chunk.toString());
      callback();
    }
  });
  morgan('combined', { stream: myStream })(req, res, next);
});

any idea how to make it work with logger like morgan ?

Tried something like this:

const { Writable } = require('stream');

app.use((req, res, next) => {
  process.stdout = new Writable({
    write(chunk, encoding, callback) {
      req.context.log(chunk.toString());
      callback();
    }
  });
  next();
});

app.use(morgan('combined'));

but didn’t work
