_/tsm-vs-esno

何をしたかったか

lukeed/tsm と esbuild-kit/esno と esbuild-kit/tsx の比較

環境:

• Node v17.9.0
• GitHub Codespaces 4-core/8GB RAM/32GB

サンプルコード:

#!/usr/bin/env tsm
// dummy
import "typescript";
const message: string = "hello world";
console.log(message);

#!/usr/bin/env esno
// dummy
import "typescript";
const message: string = "hello world";
console.log(message);

#!/usr/bin/env esmo
// dummy
import "typescript";
const message: string = "hello world";
console.log(message);

#!/usr/bin/env tsx
// dummy
import "typescript";
const message: string = "hello world";
console.log(message);

// dummy
import "typescript";
const message: string = "hello world";
console.log(message);

time npx --call 'bash -c "for i in {1..10}; do ./hello-world.tsm.ts > /dev/null 2>&1; done"'
time npx --call 'bash -c "for i in {1..10}; do ./hello-world.esno.ts > /dev/null 2>&1; done"'
time npx --call 'bash -c "for i in {1..10}; do ./hello-world.esmo.ts > /dev/null 2>&1; done"'
time npx --call 'bash -c "for i in {1..10}; do ./hello-world.tsx.ts > /dev/null 2>&1; done"'
time npx --call 'bash -c "for i in {1..10}; do node -r tsm hello-world.ts > /dev/null 2>&1; done"'
time npx --call 'bash -c "for i in {1..10}; do node --loader tsm hello-world.ts > /dev/null 2>&1; done"'
time npx --call 'bash -c "for i in {1..10}; do node --loader tsx hello-world.ts > /dev/null 2>&1; done"'
time npx --call 'bash -c "for i in {1..10}; do node -r esbuild-register hello-world.ts > /dev/null 2>&1; done"'

結果

サイズ: esno のほうが、依存関係が多いのでややサイズ大きいが esbuild 本体に比べれば誤差程度

パフォーマンス: tsm のほうがパフォーマンス高い

感想

ここまで見た範囲では tsm 優位か
