# express for ESP32 using Arduino IDE

Fast, unopinionated, (subset of a) minimalist web framework for ESP32 Arduino.

*looking for help* I'm looking for Arduino drop-in replacements for std::map and std::vector (understanding the memory contraints and possible issues in a ltd memory environment).

## Getting started

### Hello world example

Below is essentially the simplest Arduino express app you can create. 

```cpp

...

#include 

using namespace EXPRESS_NAMESPACE;

EXPRESS_CREATE_INSTANCE();

void setup() {

  ...

  app.get(F("/"), [](request &req, response &res) {

    res.send(F("Hello World!"));

  });

  app.listen(3000, []() { // creates and runs server

    LOG_I(F("Example app listening on port"), app.port);

  });

}

void loop() {

  app.run();

}

```

## Dependencies

Ethernet library (for ESP32 with W5500).

## Use of Containers

This lib uses 2 types of containers: vector and map and work fine in the ESP32 environment. Not do much so in the Arduino environment and I'm looking for drop-in replacements. Anyone?

## ESP32 with W5500 

When you combine an ESP32 with the W5500 chip, you need to patch Server.h as reported [here](https://github.com/PaulStoffregen/Ethernet/issues/42).

this `virtual void begin(uint16_t port=0) =0;` must be changed into `virtual void begin() =0;`
