    1. Quick use

    1.1 npm reference

    npm i disable-devtool
    import disableDevtool from 'disable-devtool';

    1.2 script attribute configuration

    <script disable-devtool-auto src='https://cdn.jsdelivr.net/npm/disable-devtool/disable-devtool.min.js'></script>

    Or use cdn with version:

    <!--Use a specific version-->
    <script disable-devtool-auto src='https://cdn.jsdelivr.net/npm/disable-devtool@x.x.x/disable-devtool.min.js'></script>
    <!--Use latest version-->
    <script disable-devtool-auto src='https://cdn.jsdelivr.net/npm/disable-devtool@latest/disable-devtool.min.js'></script>

    2. Function

    disable-devtool can disable all the methods that can enter the developer tools to prevent ‘code handling’ through the developer tools

    The library has the following features:

    1. Support configurable whether to disable the right-click menu
    2. Disable f12 and ctrl+shift+i shortcuts
    3. Support recognition to open the developer tools from the browser menu bar and close the current page
    4. Developers can bypass the disablement (use tk and md5 encryption for url parameters)
    5. Multiple monitoring modes, support almost all browsers (IE, 360, qq browser, FireFox, Chrome, Edge...)
    6. Highly configurable
    7. Minimal use, small size (only 7kb)
    8. Support npm reference and script tag reference (attribute configuration)
    9. Identify the real mobile terminal and browser developer tool settings plug-in forged mobile terminal, saving performance for the mobile terminal

    3. Use

    3.1 Configuration parameters when using npm

    Install disable-devtool

    npm i disable-devtool
    import disableDevtool from 'disable-devtool';

    The parameters and descriptions in options are as follows:

    declare interface optionStatic {
        md5?: string; // Bypass the disabled md5 value, see 3.2 for details, the bypass disable is not enabled by default
        url?: string; // Jump to the page when closing the page fails, the default value is localhost
        tkName?: string; // Bypass the url parameter name when disabled, the default is ddtk
        ondevtoolopen?(type: DetectorType): void; // Callback for opening the developer panel, the url parameter is invalid when it is enabled, and the type is the monitoring mode, see 3.5 for details
        interval?: number; // Timer interval is 200ms by default
        disableMenu?: boolean; // Whether to disable the right-click menu The default is true
        stopIntervalTime?: number; // Waiting time to cancel monitoring on mobile
        clearIntervalWhenDevOpenTrigger?: boolean; // Whether to stop monitoring after triggering
    declare type DETECTOR_TYPE = -1 | 0 | 1 | 2 | 3;

    3.2 md5 and tk bypass disable

    The combination of key and md5 in the library allows developers to bypass the disabling online.

    The process is as follows:

    First specify a key a (the value should not be recorded in the code), use md5 encryption to obtain a value b, and pass in b as the md5 parameter. Developers only need to bring the url parameter ddtk=a when accessing the url. Bypass disabled.

    The disableDevtool object exposes the md5 method, which can be used by developers when encrypting:


    3.3 script uses attribute configuration



    1. If you want to automatically disable,you must bring the disable-devtool-auto attribute when configuring attributes
    2. Attribute configuration is optional, the fields are the same as in 3.1, the difference is that the hump form is changed to horizontal line division
    3. The script tag is recommended to be placed at the bottom of the body

    3.4 script does not use attribute configuration

    <script src='https://cdn.jsdelivr.net/npm/disable-devtool/disable-devtool.min.js'></script>
            // The parameters are the same as in 3.1

    3.5 Monitoring Mode

    Disable-Devtool has four monitoring modes, DisableDevtool.DETECTOR_TYPE is all monitoring modes

    const DETECTOR_TYPE = {
         UNKONW: -1,
         TO_STRING: 0,
         DEFINE_ID: 1,
         SIZE: 2,

    The callback parameter of the ondevtoolopen event is the triggered monitoring mode


    npm i disable-devtool
