Class constructor VuexModule cannot be invoked without 'new' about vuex-module-decorators HOT 27 CLOSED

I think this is a very good example of how to use https://github.com/Armour/vue-typescript-admin-template

from vuex-module-decorators.

v0.8.0 - all ok
v0.9.0 - occurs this error (Class constructor VuexModule cannot be invoked without 'new')

from vuex-module-decorators.

@ruifigueira
In that case

transpileDependencies: ['vuex-module-decorators'] 

in your vue.config.js should work

from vuex-module-decorators.

Can you show the code ?

from vuex-module-decorators.

It's example with counter from README

from vuex-module-decorators.

Just upgraded to 0.5.0 and I'm also getting this. I think a full working sample application in this repo would be extremely useful.

from vuex-module-decorators.

I'm experiencing the same issues after upgrading to 0.5.0

@Module({ namespaced: true })
export class VacationCalendarVuexModule extends VuexModule {
    ...
}

it produces the following error

Uncaught TypeError: Class constructor VuexModule cannot be invoked without 'new'
    at new VacationCalendarVuexModule (vacation-calendar.ts:78)
    at Object.stateFactory (stateFactory.js:4)
    at stateFactory (index.js:8)
    at eval (index.js:10)
    at __decorate (vacation-calendar.ts:40)
    at eval (vacation-calendar.ts:137)
    at Object../ClientApp/store/modules/vacation-calendar.ts (bootstrap:791)
    at __webpack_require__ (bootstrap:724)
    at fn (bootstrap:101)
    at eval (index.ts:7)

Inspecting the line at vacation-calendar.ts:78 for me shows this

_this = _possibleConstructorReturn(this, _getPrototypeOf(VacationCalendarVuexModule).apply(this, arguments));

specifically the .apply seems to be failing.

from vuex-module-decorators.

the same issue,look forward to come out a solution

from vuex-module-decorators.

most likely to work fine with v0.6.0

from vuex-module-decorators.

This error also occurs when use version 0.6.0

from vuex-module-decorators.

yes, the error occurs at version 0.6.0 as the same

from vuex-module-decorators.

Can you guys show me your webpack/rollup configs ? I feel this is a es6 -> es5 transpilation level issue

from vuex-module-decorators.

v0.7.1 really totally fixes this. I finally figured out what the issue was

from vuex-module-decorators.

from vuex-module-decorators.

I had the same issue, I even tried transpileDependencies: ['vuex-module-decorators'] but it didn't work.

I had to use 0.8.0 version instead (thanks @KleinMaximus!).

from vuex-module-decorators.

are you using Typescript only or Typescript + Babel setup ?

from vuex-module-decorators.

Typescript + Babel (I used vue-cli for the setup).

from vuex-module-decorators.

I have same issue.
My TS transpile option is 'esnext'. and i had 0.9.0 version.
but i set transpileDependencies: ['vuex-module-decorators'], then it's works.

from vuex-module-decorators.

I have 0.9.0 installed and I tried adding this to my vue.config.js

module.exports = {
transpileDependencies: ['vuex-module-decorators']
}

still get the error and my tsconfig looks like this:

{
"compilerOptions": {
"target": "esnext",
"module": "esnext",
"strict": true,
"jsx": "preserve",
"importHelpers": true,
"moduleResolution": "node",
"experimentalDecorators": true,
"esModuleInterop": true,
"allowSyntheticDefaultImports": true,
"sourceMap": true,
"baseUrl": ".",
"types": [
"webpack-env",
"mocha",

"vuetify"

"paths": {

"dom",

"src//*.ts",
"src//.tsx",
"src/**/.vue",
"tests//*.ts",
"tests//*.tsx"
],
"exclude": [
"node_modules"
]
}

from vuex-module-decorators.

And FYI 0.8.0 works, no issues.

from vuex-module-decorators.

transpileDependencies: ['vuex-module-decorators'] works for me

from vuex-module-decorators.

@championswimmer what i have to do if I dont use vue-cli and my tsconfig target is es5?

from vuex-module-decorators.

Depending on your tool you need to make sure your transpiler transpiles this module vuex-module-decorators too.

If ES5 support is not utterly essential, you can make your entire project target es2015, in which case the library will work as it is.

from vuex-module-decorators.

@KleinMaximus with .90?

@championswimmer this is all I have in my vue.config.js

module.exports = {
transpileDependencies: ['vuex-module-decorators']
}

from vuex-module-decorators.

I also meet this problem when updating my code, add transpileDependencies: ['vuex-module-decorators'] fix it.

https://github.com/Armour/vue-typescript-admin-template now is with the latest version of vuex-module-decorators

from vuex-module-decorators.

@aceven24 Did you ever solve this? I just created a new TypeScript project with the latest Vue CLI yesterday, and whether or not I set transpileDependencies in my vue.config.js makes no difference.

EDIT: Never mind, it does work. Ended up being a caching issue. Do note that you'll also need babel.config.js for transpileDependencies to work.
