# vue/next-tick-style

enforce Promise or callback style in nextTick

🔧 The --fix option on the command line (opens new window) can automatically fix some of the problems reported by this rule.

# 📖 Rule Details

This rule enforces whether the callback version or Promise version (which was introduced in Vue v2.1.0) should be used in Vue.nextTick and this.$nextTick.

<script>
import { nextTick as nt } from 'vue';

export default {
  async mounted() {
    /* ✓ GOOD */
    nt().then(() => callback());
    await nt(); callback();
    Vue.nextTick().then(() => callback());
    await Vue.nextTick(); callback();
    this.$nextTick().then(() => callback());
    await this.$nextTick(); callback();

    /* ✗ BAD */
    nt(() => callback());
    nt(callback);
    Vue.nextTick(() => callback());
    Vue.nextTick(callback);
    this.$nextTick(() => callback());
    this.$nextTick(callback);
  }
}
</script>

# 🔧 Options

Default is set to promise.

{
  "vue/next-tick-style": ["error", "promise" | "callback"]
}

"promise" (default) ... requires using the promise version.
"callback" ... requires using the callback version. Use this if you use a Vue version below v2.1.0.

# `"callback"`

<script>
import { nextTick as nt } from 'vue';

export default {
  async mounted() {
    /* ✓ GOOD */
    nt(() => callback());
    nt(callback);
    Vue.nextTick(() => callback());
    Vue.nextTick(callback);
    this.$nextTick(() => callback());
    this.$nextTick(callback);

    /* ✗ BAD */
    nt().then(() => callback());
    await nt(); callback();
    Vue.nextTick().then(() => callback());
    await Vue.nextTick(); callback();
    this.$nextTick().then(() => callback());
    await this.$nextTick(); callback();
  }
}
</script>
