Trim Laravel Cloud Build Time

I've been using Laravel Cloud a bunch lately. Build times take about 18 seconds on the app that I'm working on. My entire build script used to be:

1composer install --no-dev --no-interaction --prefer-dist --optimize-autoloader
2npm ci --audit false
3npm run build

Simple and clean.

Well, if you want something less simple and clean, but a little bit faster, you can speed up your builds by parallelizing (almost) everything. Here's my current script. It:

Runs everying it can in parallel
Fails as fast as possible
Still gets you the command output in the end

Maybe it's not worth it, but while I'm iterating fast, the 11s build feels a lot better than the 18s one!

 1composer_log=$(mktemp)
 2npm_log=$(mktemp)
 3build_log=$(mktemp)
 4 
 5cleanup() {
 6  rm -f "$composer_log" "$npm_log" "$build_log"
 7}
 8trap cleanup EXIT
 9 
10# Start composer install in bg
11composer install --no-dev --no-interaction --prefer-dist --optimize-autoloader > "$composer_log" 2>&1 &
12composer_pid=$!
13 
14# Start npm install in fg because "run build" depends on it
15echo "--- npm install ---"
16npm ci --audit false
17npm_status=$?
18 
19if [ $npm_status -ne 0 ]; then
20  echo "[!] npm ci failed"
21  kill $composer_pid 2>/dev/null
22  wait $composer_pid 2>/dev/null
23  echo "--- composer install (maybe partial) ---"
24  cat "$composer_log"
25  exit 1
26fi
27 
28npm run build > "$build_log" 2>&1 &
29build_pid=$!
30 
31wait $composer_pid
32composer_status=$?
33 
34echo "--- composer install ---"
35cat "$composer_log"
36 
37if [ $composer_status -ne 0 ]; then
38  echo "[!] composer failed"
39  kill $build_pid 2>/dev/null
40  wait $build_pid 2>/dev/null
41  echo "--- npm build (maybe partial) ---"
42  cat "$build_log"
43  exit 1
44fi
45 
46wait $build_pid
47build_status=$?
48 
49echo "--- npm build ---"
50cat "$build_log"
51 
52if [ $build_status -ne 0 ]; then
53  echo "[!] npm build failed"
54  exit 1
55fi

Enjoy!
