Dockerfile

# syntax = docker/dockerfile:1.4

# This Dockerfile is used to build the eRPC server image.
# Docker build stages:
#     - go-builder -> build the go binary
#     - ts-core -> Core stage for TS related stuff (just installing pnpm)
#     - ts-dev -> Install dev dependencies and compile the SDK
#     - ts-prod -> Install prod dependencies only
#     - final -> Final stage where we copy the Go binary and the TS files
