Evergreen Waterfall CI

The MongoDB Shell

This repository is a monorepo for all the various components in the MongoDB Shell across all environments (REPL, Browser, Compass, etc).

For our official documentation, please visit MongoDB Docs page.

MongoDB Shell works with MongoDB servers >= 4.0.

MongoDB Shell Example


You can get the release tarball from our Downloads Page. We currently maintain MongoDB Shell on three different platforms - Windows (zip), MacOS (zip) and Linux (tgz, deb and rpm). Once downloaded, you will have to extract the binary and add it to your PATH variable. For detailed instructions for each of our supported platforms, please visit installation documentation.

Local Development


  • Node.js v16.x
  • Python 3.x
    • The test suite uses mlaunch for managing running mongod, you can install that manually as well via pip3 install mtools[mlaunch] if the automatic installation causes any trouble.


npm install -g lerna
npm install -g typescript
npm run bootstrap

Running Tests

Run all tests (this may take some time):

npm test

Run tests from a specific package:

lerna run test --scope @mongosh/cli-repl

Run tests with all output from packages:

lerna run test --stream

To test against a specific version, the MONGOSH_SERVER_TEST_VERSION environment variable can be set to a semver string specifying a server version.

Starting the CLI

Via npm:

npm run start

Alternatively you can also run start inside the cli-repl package, if you're sure everything else is compiled:

cd packages/cli-repl && npm run start


Compile all Typescript:

npm run compile-ts

Compile just the CLI:

npm run compile-cli

Compile the standalone executable (this may take some time):

npm run compile-exec

Relevant environment variables for compiling are:

  • NODE_JS_VERSION: Specify a Node.js version to use for compilation, e.g. 16.15.0 or 16.x
  • BOXEDNODE_CONFIGURE_ARGS: Node.js configure flags as a comma-separated list or JSON array, e.g. --shared-openssl,--shared-zlib
  • BOXEDNODE_MAKE_ARGS: Node.js make args (no distinction from BOXEDNODE_CONFIGURE_ARGS on Windows) as a comma-separated list or JSON array, e.g. -j12

Compile a specific package, e.g. the .deb for Debian:

npm run compile-exec
npm run evergreen-release package -- --build-variant=deb-x64

Compilation and packaging output is written to dist/.
