Base64 File loading, converting and saving for node.js
This is an ideal way to load or convert local files to base64 either for use as a string or to save on disk.
install npm i --save js-base64-file
| method | params | description |
|---|---|---|
| load | path,fileName,callback | loads a local file and converts it to base64 if needed. note : path should always end with a slash |
| loadSync | path,fileName | same as load, but it returns the base64 string instead of passing it to a callback. This could be slow on really large files. |
| save | data,path,fileName,callback | saves the data to the specified path and filename |
| callback | params | description |
|---|---|---|
| load | err, base64Data | gives you the base64 encoded file data |
| save | err | will pass any errors back |
Examples
loading and converting an image for use in the browser as a data URI
const Base64File=require('js-base64-file');
const image=new Base64File;
const file='test.png';
//path should alwas end in a /
const path=`${__dirname}/`;
//this will load and convert if needed
const data=image.loadSync(path,file);
console.log('you could send this image via ws or http to the browser now : \n',data);
saving the above converted image for later use.
image.save(data,path,`copy-b64-${file}`);
It's that simple! And it will work with any file type!
