escape

Simple library for escape or unescape HTML, String, SQL,… :D

API

Escape HTML

import { escapeHtml } from "https://deno.land/x/escape/mod.ts";

1. escapeHtml(string: string): string

Escape special characters in the given string of text, such that it can be interpolated in HTML content.

This function will escape the following characters: ", ', &, <, and >.

Note that the escaped value is only suitable for being interpolated into HTML as the text content of elements in which the tag does not have different escaping mechanisms (it cannot be placed inside <style> or <script>, for example, as those content bodies are not HTML, but CSS and JavaScript, respectively; these are known as “raw text elements” in the HTML standard).

Example

The escapeHtml function is designed to accept a string input of text and return an escaped value to interpolate into HTML.

import { escapeHtml } from "https://deno.land/x/escape/mod.ts";

console.log(escapeHtml("<script>sample</script>"));
// Result: '&lt;script&gt;sample&lt;/script&gt;'

2. isEscape(string: string): boolean

This function will check exist escape the following characters: ", ', &, <, and >.

Example

import { isEscape } from "https://deno.land/x/escape/mod.ts";

console.log(isEscape("<script>sample</script>"));
// Result: true

Un Escape HTML

import { unescapeHtml } from "https://deno.land/x/escape/mod.ts";

1. unescapeHtml(string: string): string

Convert HTML entities to HTML characters, e.g. > converts to >.

Example

The unescapeHtml function is designed to accept a string input of text and return an un-escaped value to interpolate into HTML.

import { unescapeHtml } from "https://deno.land/x/escape/mod.ts";

console.log(unescapeHtml("<script>sample</script>"));
// Result: '<script>sample</script>'

2. isUnescape(string: string): boolean

This function will check exist unescape the following characters: &, >, <, :, " and '.

Example

import { isUnescape } from "https://deno.land/x/escape/mod.ts";

console.log(isUnescape("<script>sample</script>"));
// Result: true

Escape SQL

import { escapeSql } from "https://deno.land/x/escape/mod.ts";

1. escapeSql(SqlString: string): string

Escape SQL special characters and quotes in strings.

Example

The unescapeHtml function is designed to accept a sql string and return an escaped sql string.

import { escapeSql } from "https://deno.land/x/escape/mod.ts";

console.log(escapeSql("insert into table_exp values('hi, my name''s johnny.');"));
// Result: 'insert into my_table values(\'hi, my name\'\'s johnny.\');'
