我遇到了非常有用但似乎没有文档的诊断开关.

例如,这里是我现在在我的项目上运行tsc –noEmit –diagnostics时所得到的：

Files:             231
Lines:           50872
Nodes:          170067
Identifiers:     65994
Symbols:       7712123
Types:          407677
Memory used:   600554K
I/O read:        0.43s
I/O write:       0.00s
Parse time:      1.13s
Bind time:       0.34s
Check time:     10.17s
Emit time:       0.00s
Total time:     11.64s

当我在早期版本的项目中运行相同的命令时,这是我得到的.

Files:             197
Lines:           30882
Nodes:          124208

I/O read:        0.03s
I/O write:       0.00s

Check time:      0.93s
Emit time:       0.00s
Total time:      1.79s

类型的数量已经上升,检查时间也是如此.

是否可以从–diagnostics获取更详细/详细的输出？

NodeJS v4.4.3,TypeScript v1.8.10.这是我的tsconfig.json

{
  "compilerOptions": {
    "target": "es5","module": "system","moduleResolution": "node","noImplicitAny": false,"noEmitOnError": false,"experimentalDecorators": true,"emitDecoratorMetadata": true,"removeComments": false
  },"exclude": [
    "node_modules","wwwroot","typings/main.d.ts","typings/main"
