Install Experiments!

This repo gives a simple test of what happens with npm v3, flattening, and incremental npm updates.

Starting Point

root>/package.json

ependencies": {
"builder": "2.9.0",
"lodash": "^3.10.1"

Builder has the exact same lodash requirements: "^3.10.1"

Commands:

m install
all-experiments@0.0.1 /Users/rroemer/scm/fmd/install-experiments
builder@2.9.0
? SNIPPED
lodash@3.10.1

Where is lodash?

nd . -name lodash
de_modules/lodash

Experiment - npm install

Now, let's upgrade lodash via package.json!

root>/package.json

ependencies": {
"builder": "2.9.0",
"lodash": "^4.8.2"

With this diff:

it diff
 --git a/package.json b/package.json
x 1e79df8..1330008 100644
a/package.json
b/package.json
6,6 +6,6 @@
license": "MIT",
dependencies": {
 "builder": "2.9.0",
 "lodash": "^3.10.1"
 "lodash": "^4.8.2"

And now just run another npm install:

m install
all-experiments@0.0.1 /Users/rroemer/scm/fmd/install-experiments
builder@2.9.0
? lodash@3.10.1
lodash@4.8.2

Where is lodash? Looks to be in both places, as we want:

nd . -name lodash
de_modules/builder/node_modules/lodash
de_modules/lodash

Conclusion: Works as expected.

Experiment - npm install –save VERSION

Now, let's upgrade lodash via the command line!

m install --save lodash@4.8.2
all-experiments@0.0.1 /Users/rroemer/scm/fmd/install-experiments
builder@2.9.0
? lodash@3.10.1
lodash@4.8.2

Where is lodash? Looks to be in both places, as we want:

nd . -name lodash
de_modules/builder/node_modules/lodash
de_modules/lodash

Conclusion: Works as expected.

Experiment - npm shrinkwrap

First, let's shrinkwrap:

m shrinkwrap

Baseline test: re-install from scratch produces same tree:

 -r node_modules
m install
all-experiments@0.0.1 /Users/rroemer/scm/fmd/install-experiments
builder@2.9.0
? SNIPPED
lodash@3.10.1

Update the shrinkwrap. Diff:

 --git a/package.json b/package.json
x 0927aed..7bcd26e 100644
a/package.json
b/package.json

 "builder": "2.9.0",
 "lodash": "^3.10.1"

Remove existing shrinkwrap and recreate:

 npm-shrinkwrap.json
m install
m shrinkwrap

produces the expected diff:

 --git a/npm-shrinkwrap.json b/npm-shrinkwrap.json
