[lukeed/tsm](https://github.com/lukeed/tsm) と [antfu/esno](https://github.com/antfu/esno) の比較
|
|
|
|
環境:
|
|
|
|
- Node v17.9.0
|
|
- GitHub Codespaces 4-core/8GB RAM/32GB
|
|
|
|
サンプルコード:
|
|
|
|
```ts
|
|
#!/usr/bin/env tsm
|
|
// dummy
|
|
import "typescript";
|
|
const message: string = "hello world";
|
|
console.log(message);
|
|
```
|
|
|
|
```ts
|
|
#!/usr/bin/env esno
|
|
// dummy
|
|
import "typescript";
|
|
const message: string = "hello world";
|
|
console.log(message);
|
|
```
|
|
|
|
```ts
|
|
#!/usr/bin/env esmo
|
|
// dummy
|
|
import "typescript";
|
|
const message: string = "hello world";
|
|
console.log(message);
|
|
```
|
|
|
|
```ts
|
|
// dummy
|
|
import "typescript";
|
|
const message: string = "hello world";
|
|
console.log(message);
|
|
```
|
|
|
|
```sh
|
|
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 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 -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
|
|
|
|
```console
|
|
$ time npx --call 'bash -c "for i in {1..10}; do ./hello-world.tsm.ts > /dev/null 2>&1; done"'
|

|
real 0m4.848s
|
|
user 0m4.608s
|
|
sys 0m0.695s
|
|
|
|
$ time npx --call 'bash -c "for i in {1..10}; do ./hello-world.esno.ts > /dev/null 2>&1; done"'

|
|
|
ここまで見た範囲では tsm 優位か
