Getting Started

Make sure if Node 14+ is installed on your computer.

Step 1: Create a new Lerna workspace by running:

$ cd /{your_directory}/monorepo-react-template
$ npx lerna init

Step 2: Install dependencies (Required)

It will automatically install the dependencies of all resources in packages/ without duplication.

$ npm install

Step 3: To open the visualization, run:

$ npx nx graph

Step 4: To build all projects, run

$ npm run cra:init
$ npm run grpc:init
$ npx lerna run build

or Build the package you want (recommend):

$ npm run cra:init
$ npm run grpc:init
$ npx lerna run build --scope=plugin-1 --scope=plugin-2 --scope=plugin-component

Please do not install lerna globally to use lerna run build

Step 5: (optional) Use a custom script like:

$ npx lerna exec npm run export --scope=plugin-2

Make sure that packages/plugin-component is copied to node_modules, Because packages/plugin-1 depends on the packages/plugin-component.

projects in packages/ should not include the node_modules/ folder

The scripts configuration of the project in the packages needs to support the global, for example, the react-scripts command does not exist. You need to install it globally first. The same goes for other commands.

$ sudo npm install --g react-scripts

the same to:

$ sudo npm install --g webpack webpack-cli

Project dependencies in packages other than packages/front-end should be configured in the package.json file in the root directory.

If the npm package installation fails, execute the following command and then install it

$ sudo npm cache clean --force

or

$ sudo chown -R 501:20 "/Users/<YOUR_USER_NAME>/.npm"

Failure Logs:

NX dlopen(/<package_name>/node_modules/@nrwl/nx-darwin-x64/nx.darwin-x64.node, 1): no suitable image found. Did find:

/<package_name>/node_modules/@nrwl/nx-darwin-x64/nx.darwin-x64.node: cannot load 'nx.darwin-x64.node' (load command 0x80000034 is unknown)
/<package_name>/node_modules/@nrwl/nx-darwin-x64/nx.darwin-x64.node: cannot load 'nx.darwin-x64.node' (load command 0x80000034 is unknown)

If the above error occurs, please make sure that the nx package, that is, node_modules/@nrwl version is 15.7.2, versions above 15.8.x cannot run lerna and nx commands correctly.

The kernel version of nx is related to your OS (Operating System). If you cannot use the Lerna or NX command normally, please upgrade your OS or downgrade the nx version (configure the dependency of package.json).

OR, In case something breaks though, you can also disable the Rust hasher by using the environment variable NX_NON_NATIVE_HASHER=true. This will cause the task runner to use git to hash files instead of the rust-powered native implementation (which is faster).

⚙️ Custom Configuration of Build

Excluding dependencies from the output bundles, you could change the package.json like this:

The buildConfig property will be linked to the Webpack configuration.

{
    ...
    "buildConfig": {
        "externals": {
            "react": "React",
            "react-dom": "ReactDOM"
        }
    },
    ...
}

If you want to cancel the external files setting, please change it to:

{
    ...
    "buildConfig": {
        "externals": ""
    },
    ...
}
