egg + ts dev bug #2330

HaveF · 2018-04-06T10:48:41Z

Node Version:
node --version
v9.10.1
Egg Version:
"egg": "^2.6.0",
Plugin Name:
Plugin Version:
Platform:
Mini Showcase Repository:

完全按照当 Egg 遇到 TypeScript，收获茶叶蛋一枚 · Issue #27 · atian25/blog中的快速入门部分尝试

$ npx egg-init --type=ts showcase
$ cd showcase && npm i
$ npm run dev

先注释了一下home.ts中的
// ctx.body = await ctx.service.test.sayHi('egg');
然后再取消注释
npm run dev就崩了

npm run dev

> [email protected] dev /Users/HaveF/Desktop/newTech/eggWithTs
> egg-bin dev -r egg-ts-helper/register

[egg-ts-helper] These file was deleted because of the same name ts file was exist!

看起来你是 tsc 过，导致 js 和 ts 文件同时存在，loader 加载了 2 次。
执行下 npm run clean

你是不是开了什么插件之类的，有 tsc 在后台自动编译了？

HaveF · 2018-04-06T11:11:55Z

感谢天猪
奇怪, 我并没有做tsc之类的动作啊...前面用的是webstorm的默认配置

我删除又重做了下, 这次提示是否将ts编译成js, 选了no, 发现确实没有问题了
(上一次好像没有做任何类似动作)
感谢感谢

另外这个错误有可能在什么地方表示的更清晰些吗? 比如你说的loader加载了两次?

atian25 · 2018-04-06T11:14:08Z

Error: can't overwrite property 'home' from /Users/HaveF/Desktop/newTech/eggWithTs/app/controller/home.js by /Users/HaveF/Desktop/newTech/eggWithTs/app/controller/home.ts

写的很清楚了，先加载了 js 文件，然后再加载了 ts

waitingsong · 2018-04-07T10:20:22Z

@atian25 我觉得还是把开发目录和编译目录分开的比较好。虽然根据日志能清楚查出问题，但这个不是解决办法。估计以后还会有人会遇到相同问题。有看日志的可能可以解决，没仔细看日志的就只有上来报bug……

atian25 · 2018-04-07T23:12:31Z

在规范里面没有约束编译目录，只是对开发期做了约束，开发者自行配置就好了。他这个问题是 webstorm 自带的一个 watcher 搞的

atian25 · 2018-04-07T23:13:12Z

不看日志只会报 issue 的谁都没辙

nimoc · 2019-05-01T08:31:14Z

今天遇到相同的问题，留个备注防止后人踩坑。

atom-typescript 在 tsconfig.json 设置 compileOnSave: true 后会自动编译，就跟npm run dev 的编译冲突了。关闭 "compileOnSave":false 即可

后续进展

直接使用 midway （基于 egg 支持 typescript 依赖注入）

nimoc · 2019-05-01T16:20:24Z

如果希望使用ide的编译，以避免报错出现在终端/命令行中。设置 tsconfig.json compileOnSave 为 true
修改package.json 中 egg.typescript 为false
config/config.default.ts 新增

let reloadPattern = ['**']
  if (require('../package.json').egg.typescript === false) {
    reloadPattern.push('!**/*.ts')
  }
  config.development = {
    reloadPattern
  }

npm run dev 的 package.json 中要改为 ""dev": "tsc && egg-bin dev","

以后想切换回来就修改 compileOnSave 和 typescript
