Menu
I'm currently upgrading my application from Vue.js 1 to Vue.js 2. I have a problem with the following function in my main component:
<script>
export default {
ready: function listenKeyUp() {
window.addEventListener('keyup', this.handleKeyUp());
},
methods: {
handleKeyUp(e) {
if (e.keyCode === 27) {
this.$router.go({ name: '/' });
}
},
},
};
</script>
My console shows this error: 'window' is not defined
How is this possible? I don't understand the reason. How to fix this and why is this problem coming up with the new version?
--- EDIT --- Some additional code:
main.js:
// Import plugins
import Vue from 'vue';
import VueResource from 'vue-resource';
import VueI18n from 'vue-i18n';
// Import mixins
import api from './mixins/api';
// Import router config
import router from './router';
// Register plugins
Vue.use(VueResource);
Vue.use(VueI18n);
Vue.mixin(api);
// Go
new Vue({
router,
}).$mount('#app');

The safest place to use browser references is the mounted() lifecycle hook. Especially if you're using a SSR setup like Nuxt.js or similar.

It's related to Eslint. Putting this:
"env": {
"browser": true,
"node": true
}
inside .eslintrc.js in my root fixed the issue. (source)
