[uinz]

default

const V = require('fastest-validator');

const v = new V();

const schema = {
  tuple: {
    type: 'tuple',
    empty: false,
    items: [{ type: 'string', default: '1' }],
  },
};

const data = { tuple: [] };
console.log(v.validate(data, schema));
console.log(data);

[
  {
    type: 'tupleEmpty',
    message: "The 'tuple' field must not be an empty array.",
    field: 'tuple',
    actual: []
  }
]
{ tuple: [] }

optional

const schema = {
  tuple: {
    type: 'tuple',
    empty: false,
    items: [
      { type: 'string' },
      { type: 'number', optional: true },
    ],
  },
};

const data = { tuple: ['str', undefined] };
console.log(v.validate(data, schema));
console.log(data);

[
  {
    type: 'number',
    message: "The 'tuple[1]' field must be a number.",
    field: 'tuple[1]',
    actual: undefined
  }
]
{ tuple: [ 'str', undefined ] }

I would call this a critical bug. The empty: true rule won't work either, we need to fix the list of properties that should be checked at the top level of the rule.
