If some snippets do not show up, add the following to your settings file

    "configurationDefaults": {
        "files.associations": {
            "*.ejs": "html"
        },
        "emmet.includeLanguages": {
            "ejs": "html"
        }
    }

or you can dowinlode mern-snippets-0.0.1.vsix frome : https://github.com/moh2medkhaled/mern-snippets/blob/master/mern-snippets-0.0.1.vsix

This problem occurs because vs code deletes this command frome package.json. This problem may appear when using EJS - HBS - MongoDB snippets
