Here's a function to escape characters on when inserting to redis. I believe all you need to do is add an extra slash to the replacement value when you're replacing a search value.

function redisReplace(value) {
const replacements = {
    ',': '\\,', 
    '.': '\\.',
    '<': '\\<',
    '>': '\\>',
    '{': '\\{',
    '}': '\\}',
    '[': '\\[',
    ']': '\\]',
    '"': '\\"',
    "'": "\\'",
    ':': '\\:',
    ';': '\\;',
    '!': '\\!',
    '@': '\\@',
    '#': '\\#',
    '$': '\\$',
    '%': '\\%',
    '^': '\\^',
    '&': '\\&',
    '*': '\\*',
    '(': '\\(',
    ')': '\\)',
    '-': '\\-',
    '+': '\\+',
    '=': '\\=',
    '~': '\\~',
}

const newValue = value.replace(/,|\.|<|>|\{|\}|\[|\]|"|'|:|;|!|@|#|\$|%|\^|&|\*|\(|\)|-|\+|=|~/g, function(x) {
        return replacements[x]
})
return newValue
}
