(WIP) Serverless platform aimed for microcontrollers

Isère

Isère (/iːˈzɛər/)

A serverless platform aimed to be running on Microcontrollers

The goal is to create a low-power serverless platform that can handle simple stateless request like logging in which will require accessing to database and creating JWT token

Current progress

• FreeRTOS as Kernel
• QuickJS as JavaScript runtime
  • setTimeout / clearTimeout (FreeRTOS Software Timer)
• HTTP server
  • Event Loop
  • Static Files (?)
• Unit tests
  • loader
  • js
  • httpd
  • logger
  • polyfills
    • setTimeout
• Unit tests on CI
• File System Abstraction
• Configuration File
• Integration tests
• Integration tests on CI
• Node-like APIs (ref. workerd)
  • assert
  • buffer
  • crypto
  • diagnostics_channel ❌
  • events
  • path
  • process.env
  • stream (?)
  • string_decoder
  • util
• Fetch API
• QuickJS Memory Leak Check
• Use less printf()
• QuickJS Project Template
• Low-power mode
• Benchmark
• Port to Raspberry Pi Pico (RP2040) (LittleFs + FreeRTOS+POSIX + FreeRTOS+TCP)
• Integrate with some Analytics and Monitoring Platforms
• Port to ESP32?
• MicroPython?

Limitations

• No Keep-Alive support
• JavaScript handler function needs to be stored sequentially and addressible in a Flash memory
• File system is for storing static files and configuration files

Building and Running

Prerequisites:

• automake
• make
• gcc
• libtool
• ninja (optional for building c-capnproto)

# install dependencies
brew install automake libtool ninja
# or
sudo apt install -y build-essential libtool ninja-build

git clone <this f***ing repo>
git submodule update --init

# compile dependencies
make -j deps

# compile examples javascript
make -j .examples

# compile isere
make -j

# run isere
./isere

try to access http://localhost:8080/ and see the process logs

feel free to try modify examples/echo.esm.js (don't forget to recompile it using make -j .examples)

Running Tests

make -j unittest
./unittest
