Create a Registry Index File Manually

Warning

Experimental feature

This feature is experimental. MongoDB does not provide support for Snippets. This feature may be changed or removed at any time without prior notice.

Bugs are not expected, however should you encounter one, please open an issue in the GitHub repository for this project.

This page discusses how to manually create a registry index file. To generate the registry index file using a script, see Create a Registry Index File.

To create the registry index file:

Copy the following TypeScript template and save it as make-index.ts:

import bson from 'bson';
import zlib from 'zlib';
interface ErrorMatcher {
   // Add additional information to shell errors matching one of the regular.
   // expressions. The message can point to a snippet helping solve that error.
   matches: RegExp[];
   message: string;
}
interface SnippetDescription {
   // The *npm* package name. Users do not interact with this.
   name: string;
   // The snippet name. This is what users interact with.
   snippetName: string;
   // An optional install specifier that can be used to point npm towards
   // packages that are not uploaded to the registry. For example,
   // this could be an URL to a git repository or a tarball.
   installSpec?: string;
   // A version field. Users do not interact with this, as currently, `snippet`
   // always installs the latest versions of snippets.
   version: string;
   description: string;
   readme: string;
   // License should be a SPDX license identifier.
   license: string;
   errorMatchers?: ErrorMatcher[];
}
interface SnippetIndexFile {
   // This must be 1 currently.
   indexFileVersion: 1;
   index: SnippetDescription[];
   metadata: { homepage: string };
}
const indexFileContents: SnippetIndexFile = {
   indexFileVersion: 1,
   index: [ /* ... */ ],
   metadata: { homepage: 'https://example.com' }
};
// Serialize, compress and store the index file:
fs.writeFileSync('index.bson.br',
   zlib.brotliCompressSync(
   bson.serialize(indexFileContents)));

Edit make-index.ts as needed for your snippet package. Use the comments as a guide to filling out the required information.
Run ts-node make-index.ts to create the index.bson.br file.
Upload index.bson.br to your GitHub repository.
Update snippetIndexSourceURLs to include a URL that references your index.bson.br.
