Node.js 21.1.0 - build single executable application

Sharing my project's build script in case it's useful to others. I'm not testing for Windows, which is why the script reports an error, but just note that emitting Windows executables is actually supported by the Node API (see docs). Feel free to use and modify.

Notes

  • Webpack is used for bundling.
  • The entry point for the webpack config for my example is ./bin/app, which was an executable Node.js script with a shebang line. Update the config to point to whatever your app's entry point is.
  • The SEA config file uses disableExperimentalSEAWarning to suppress the experimental warning displayed when running a generated executable. This didn't work for Node 20.1.0 (see issue), but it has been tested and does work for 21.1.0.

This simple Python file generates a random massive CSV file efficiently taking almost no RAM while doing so streaming data into your CSV file. I've pre-done the calculation of the rows/columns to the file-size, so you can easily add or remove zeroes from "rows" variable to increase or decrease the size of the file generated
import csv
import random
# 1000000 and 52 == roughly 1GB (WARNING TAKES a while, 30s+)
rows = 1000000
columns = 52
print_after_rows = 100000
def generate_random_row(col):
a = []

Installing mysql2 gem errors on Apple silicon M1, M2 or M3 Mac running macOS Sonoma.

Solution

Make sure mysql-client, openssl and zstd are installed on Mac via Homebrew.

Replace mysql-client with whichever mysql package you are using

Installing mysql2 gem

Installing mysql2 gem

This is always an annoying process, especially when you are setting up a new computer. I assume you are using macOS + homebrew. I also assume that you want to run an older version of MySQL (although the instructions should be adaptable).

Installing MySQL

$ brew install [email protected] # change the version if needed
