Vue Js Write text to file :In Vue.js, a front-end JavaScript framework, you cannot directly write text to a file on the client-side due to security restrictions. However, you can achieve a similar result by using the browser’s File API and the FileWriter object. The process involves creating a Blob (Binary Large Object) with the desired text, opening a FileWriter, and then writing the Blob’s content to it. This approach allows you to generate a file containing text, which the user can choose to download. 

How can I use Vue js to write text to a file?

The provided code demonstrates how to write text to a file using Vue.js.

The script defines a Vue instance with an element identified as “ app” and a data property named “fileContent” that holds the text to be written to the file. Inside the instance, there is a method called “generateAndDownloadFile” which creates a Blob object from the file content and sets its MIME type as plain text. A temporary URL for the blob is created using URL.createObjectURL().

Next, an anchor element is dynamically created, configured to download the file with the name “file.txt”. The anchor is appended to the document body, clicked programmatically, and then removed.

As a result, the file download prompt will be triggered, allowing the user to save the generated text as a file

Vue Js Write text to file Example

<script type="module" >
    const app = new Vue({
    el: "#app",
    data() {
        return {
            fileContent: 'To create a text file, simply click on the button below after reading the following text ',
        };
    },
    methods: {
        generateAndDownloadFile() {
            const blob = new Blob([this.fileContent], { type: 'text/plain' });
            const url = URL.createObjectURL(blob);

            const link = document.createElement('a');
            link.href = url;
            link.setAttribute('download', 'file.txt');
            document.body.appendChild(link);
            link.click();
            document.body.removeChild(link);
        },
    },
});
</script>
