How to change button property when starting a vuex-electron app? - vue.js

Question

I am working on a vuex-electron application.
There are several buttons on the main page, when clicked, a file is stored in a specific folder, and at the same time, the property of the button turns to [saved], when this [saved] button is clicked again, a message pops up, asking whether to overwrite or not the old file.
But the problem is : when the app is restarted, all of the buttons' property is initialized to [not saved], so, even though the same file has already been stored, when button is clicked, the old file is overwritten without any pop-ups asking whether to overwrite the existing file or not.
I want to change the feature as below:
when the app is restarted, check file existence first, then based on the result, change button property to [saved].
Is this possible?
If possible, where should I add the logic in.
I am a complete beginner on vue.js.
Have been looking up for a while, but did not find any useful information.
From the following thread, learned that state data is stored in a json file, does this mean I need to change the state? Currently, button properties are not saved in this json file.
Where is the state of a Electron-Vue application stored?
//code
v-for="(btn,i) in buttons" :key="i" #click="save(btn)"
computed: {
buttons() {
let r = this.$store.state.App.aData.filter(x=> {
if (this.aType==='abc') {
return x.video.toString() === '1'
} else {
return !x.video
}
}).map(x => {
let y = this.$copy(x)
y.saved = this.savedData.includes(x.index)
y.disabled = this.appState !== 'def'
return y
})
let index = this.aType==='abc'?998:999
r.push({
index,
a_name:'others',
e_number:this.aType==='abc'?'N':'999',
disabled: this.appState !== 'def',
saved: this.savedData.includes(index),
video:''
})
return r
},
},
methods:{
save(btn) {
if (btn.disabled) {
return
}
if (btn.saved) {
this.$buefy.dialog.confirm({
message: '??',
confirmText: 'overwrite?',
cancelText: 'cancel',
type: 'is-danger',
hasIcon: true,
onConfirm: () => {
if (this.aType==='xyz') {
this.saveXyz(btn)
}
if (this.aType==='abc') {
this.saveAbc(btn)
}
}
})
return
}
if (this.aType==='xyz') {
this.saveXyz(btn)
}
if (this.shootingType==='abc') {
this.saveAbc(btn)
}
},
saveXyz(data) {
if (this.xyzBuffer) {
//create a file and store to a folder
this.savedData.push(data.index)
let idx = this.$store.state.App.aData.findIndex(x=>x.index===data.index)
if (idx > -1) {
idx++
if (idx < this.$store.state.App.aData.length) {
this.selectedData = idx
this.aType = this.$store.state.App.aData[this.selectedData].video ? 'abc' : 'xyz'
this.scrollTo(this.selectedData)
}
}
this.cancel()
})
}
}
},
saveAbc(data) {
if (this.recording) {
return
}
//create a file and store to a folder
this.savedData.push(data.index)
let idx = this.$store.state.App.aData.findIndex(x=>x.index===data.index)
if (idx > -1) {
idx++
if (idx < this.$store.state.App.aData.length) {
this.selectedData = idx
this.aType = this.$store.state.App.aData[this.selectedData].video ? 'abc' : 'xyz'
this.scrollTo(this.selectedData)
}
}
this.cancel()
}
})
},
