npm: possibly marvellous

    npm module to use the github servers as an image cdn, hosting the images for the README file, and thus keeping gits as small as possible


    A nice README is important. If you're reading this, you probably know that. Markdown, the markup language of the README-file isn't exactly that flexible however. Some html is supported, but it's pretty restrictive. The usual way to make your README-file stand out is by the use of pictures. For some stores, it's even necessary to have high-res screenshots in your README. However, dropping high-res images into your git will make your awesome codebase seem really big, heavy and unorganised. Hosting your images on third-party sites is an option, but it isn't exactly easy, and it's by no means reliable. github-image-upload enables you to very easily use the Github servers themselves to host the images for your README, without even having to leave your IDE.

    This package is based on a gist from @vinkla


    locally, usually for use as a module:

    npm i github-image-upload

    globally, usually for use as a command line application:

    npm i github-image-upload -g


    Command line for projects

    github-image-upload is primarily designed to be used as a command line application.

    To do so, the package has to be installed globally.

    In your project folder, run the init command

    github-image-upload --init

    This will create a folder calles .ghimages. Inside of this folder, there's a config file called ghimages.config.js, which looks like this:

    module.exports = {
         'username': 'GITHUB_USERNAME',
         'password': 'GITHUB_PASSWORD',
         'readme_file': '../'

    In this file, the github username and github password, as well as the location of the file should be configured. For most projects, the default '../' should be correct.

    The entire .ghimages-folder is automatically added to .gitignore. This keeps your Github-credentials safe from accidentally being pushed to Github. When publishing your code on other platforms however, handle .ghimages with care. It should never be published.

    When adding images to your, put the image files in the .ghimages folder. Include them into the locally like you normally would, eg.:

    ![a nice image](./.ghimages/aReallyNiceImage.png)

    To convert upload these images to Github and replace the local references in your with references to the public Github-url's, use the following command:

    github-image-upload -c

    When new, local images are found, this command takes ~ 3.5s, plus the upload time for each image. When no new local images are found however, this is very fast, meaning that is can perfectly be included in a build sequice, eg.:


        "test": "echo \"Error: no test specified\" && exit 1",
        "start": "node ./build/index.js",
        "build": "webpack && tsc && npm run ghimage",
        "ghimage": "github-image-upload -c"

    In this example, when running npm run build or npm run ghimage, github-image-upload will do its thing. When using the package this way, as an npm script, a global installation is not needed. The prefered way to install would then be a a dev-dependency:

    npm i github-image-upload --save-dev

    Command line interactive

    Outside or project folders, the tool can also be used interactively:

    github-image-upload -i

    As a module

    import { upload as ghUpload } from 'github-image-upload'
    (async () => {
        const imgUrls = await ghUpload('GITHUB_USERNAME', 'GITHUB_PASSWORD', ['path/to/image1.png', 'path/to/image2.gif'])
          "localPath": "path/to/image1.png",
          "publicUrl": ""
          "localPath": "path/to/image2.gif",
          "publicUrl": ""


    I don't think it's explicitly stated anywhere, but given the fact that this service exists and there's no API, I assume Github doesn't exactly want you to use their image-hosting service this way. Many famous repos seem to use it manually so it doesn't look like Github has any problem with you using it, but if they would've wanted you to be able to use it automatically, I assume they would've written an API.

    github-image-upload automates the manual process, but it doesn't use an API, it rather acts like it is a human being. Github, in other words, has no way of knowing whether your computer uploads images automatically, or whether you do it manually. This technique is called web scraping. Although it's used very extensively, there has been quite a bit of legal debate about it. Sooo, just to be safe: I'm not advising you to use this package.
