Master builder for Lerna projects.
- Transpile source code with Babel, excluding tests
- Copy non-JS assets to the output directory
Install vitruvius using npm
:
npm install --save-dev vitruvius
Next add a simple npm
script to run vitruvius:
"scripts": {
"build": "vitruvius build --src src --dest lib"
}
Now, running npm run build
will look in the src
directory of each package in your project and output the compiled code in a lib
folder in each package.
vitruvius build --src <srcDirName> --dest <destDirName> [--ignore <fileGlobPatterns>]
src
(required) is the name of the source directory within each package.
dest
(required) is the name of the output directory you want to create in each package.
ignore
(optional) is an array of glob patterns for files and directories to ignore. By default, *.test.js
, *.spec.js
, **/__tests__/**
, and **/__mocks__/**
are ignored.
As a point of reference, let's consider this standard Lerna project:
my-lerna-repo/
packages/
package-1/
src/
index.spec.js
index.js
package.json
package-2/
src/
data.json
index.js
package.json
Let's say we want to compile the source code in package-1
and package-2
into a lib
folder.
To do this, we can run vitruvius build --src src --dest lib
. This will Babel compile the source code, copy any non-JS files, and ignore test files.
After building, our project now looks like this:
my-lerna-repo/
packages/
package-1/
lib/
index.js
src/
index.spec.js
index.js
package.json
package-2/
lib/
data.json
index.js
src/
data.json
index.js
package.json
As you can see, package-1/src/index.js
has been compiled into package-1/lib/index.js
, while package-1/src/index.spec.js
was ignored. And package-2/src/data.json
was copied over to package-2/lib/data.json
, along with package-2/src/index.js
being compiled to package-2/lib/index.js
.
