Writes the value in the browser web storage.

Syntax

await MFiles.WriteToWebStorage( keyName, value );

Name	Type	Description
key	string	The web storage key.
value	string	The value.

Example

This sample demonstrates the use of M-Files API functions to interact with web storage: it writes "Sample Value" to storage with the key "testKey", reads it back, logs the value to the console, and finally deletes the entry from web storage.

note

Values written to web storage must be string values, because they are internally serialized into string values.

// Called when the UI Extension starts
async function OnNewShellUI(shellUI) {

    // Write to web storage some value
    await MFiles.WriteToWebStorage( "testKey", "Sample Value" );

    // Read the value from the web storage
    const storedValue = await MFiles.ReadFromWebStorage( "testKey" );

    // Outputs: "Sample Value"
    console.log( storedValue );

    // Remove key from the storage.
    await MFiles.DeleteFromWebStorage( "testKey" );

}
