vue good table - 3 requests to the service - vue.js

Question

I use vue-good-table object to render table in Vue.js. I use paging and sorting serverside.
My code:
<vue-good-table v-if="authorizations"
id="AuthorizationsTable"
ref="refToAuthorizationsTable"
#on-page-change="onPageChange"
#on-sort-change="onSortChange"
#on-column-filter="onColumnFilter"
#on-per-page-change="onPerPageChange"
mode="remote"
:columns="columns"
:rows="authorizations"
:totalRows="totalRecords"
:pagination-options="{
enabled: true,
mode: 'pages',
nextLabel: 'następna',
prevLabel: 'poprzednia',
ofLabel: 'z',
pageLabel: 'strona',
rowsPerPageLabel: 'wierszy na stronie',
allLabel: 'wszystko',
dropdownAllowAll: false
}"
:sort-options="{
enabled: true,
initialSortBy: {
field: 'id',
type: 'asc'
}
}">
(...)
export default {
name: 'AuthoritiesAdministration',
components: {},
data() {
return {
totalRecords: 0,
serverParams: {
columnFilters: {},
sort: {
field: 'id',
type: 'asc'
},
page: 1,
perPage: 10
},
rows: [],
columns: [
{
label: 'ID',
field: 'id',
type: 'number',
tdClass: 'vue-good-table-col-100'
},
{
label: 'Data wystawienia',
field: 'issueDate',
formatFn: this.formatDate,
tdClass: 'vue-good-table-col-200',
},
{
label: 'Nazwa operatora',
field: 'operator',
sortable: true,
formatFn: this.formatOperatorName,
},
{
label: 'Login',
field: 'operator.login'
},
{
label: 'Spółka',
field: 'company.description',
type: 'text',
},
{
label: 'Data ważności',
field: 'endDate',
type: 'text',
formatFn: this.formatDate,
},
{
label: 'Akcje',
field: 'btn',
tdClass: 'vue-good-table-col-250',
sortable: false
}
],
}
},
(...)
methods: {
updateParams(newProps) {
this.serverParams = Object.assign({}, this.serverParams, newProps);
},
onPageChange(params) {
this.updateParams({page: params.currentPage});
this.loadAuthorizations();
},
onPerPageChange(params) {
this.updateParams({
perPage: params.currentPerPage
});
this.loadAuthorizations();
},
onSortChange(params) {
this.updateParams({
sort: {
type: params[0].type,
field: params[0].field
}
});
this.loadAuthorizations();
},
onColumnFilter(params) {
this.updateParams(params);
this.loadAuthorizations();
},
loadAuthorizations() {
getAllAuthorizationsLightWithPagination(this.$store.getters.loggedUser.token, this.serverParams).then(response => {
this.totalRecords = response.data.totalRecords;
this.rows = response.data.authorizations;
}).catch(err => {
this.$showError(err, true);
});
},
I have noticed that there are sent 3 requests to the server instead of 1: there are called methods like onPageChange, onPerPageChange and onSortChange but only the first time when my page is loaded. It is unnecessary. I have one method in "mounted" section where I load the first 10 results (sorting and paging by default). It's common, well-known problem with vue-good-table? Or maybe should I add an additional flag to not to invoke these 3 methods unnecessarily when the page is loaded?

Answer 1

Your onSortChange method is called at the table loading because you made a initialSortBy with specific values. To remove this calling juste remove
initialSortBy: {
field: 'id',
type: 'asc'
}
from you table configuration, but your sort will not be set, so I think this should be a legit function call.
The onPerPageChange and onPageChange are triggered by the config below
:pagination-options="{
enabled: true,
...
}
just remove the colon before pagination-options to have a config like this
pagination-options="{
enabled: true,
...
}
