### Checkin
4+
5+
- Do checkin source (src)
6+
- Do checkin build output (lib)
7+
- Do checkin runtime node_modules
8+
- Do not checkin devDependency node_modules (husky can help see below)
9+
10+
### devDependencies
11+
12+
In order to handle correctly checking in node_modules without devDependencies, we run [Husky](https://github.com/typicode/husky) before each commit.
13+
This step ensures that formatting and checkin rules are followed and that devDependencies are excluded. To make sure Husky runs correctly, please use the following workflow:
14+
15+
```
16+
npm install # installs all devDependencies including Husky
17+
git add abc.ext # Add the files you've changed. This should include files in src, lib, and node_modules (see above)
18+
git commit -m "Informative commit message" # Commit. This will run Husky
19+
```
20+
21+
During the commit step, Husky will take care of formatting all files with [Prettier](https://github.com/prettier/prettier) as well as pruning out devDependencies using `npm prune --production`.
22+
It will also make sure these changes are appropriately included in your commit (no further work is needed)
