Let's go back to our file and let's actually log out what we're requiring. It says that Sensitive Words is not a function. Save and close my file, and then run node on my index file. Now, let's console log out filter and see what it contains. Then for the second argument let's filter out the words pro and touch bar. For the first argument let's say the new Apple MacBook Pro will have a touch bar.

Now, we can require in our Sensitive Words module. Let's create a file called index.js and open that in our code editor. Now we have our node modules with the symbolic link to our package locally and our package.json. Now, if we take a look at our node modules folder, we see that it actually made a symbolic link for the Sensitive Words package as if we had installed it from MPM. Now, let's run MPM link and then paste in the name of the package that we're developing. Now let's run MPM init with the -Y flag, which will give us our default for a package.json. In another terminal pane I'm going to create a new directory called "Some Project," and let's change directories into that directory. This is "Sensitive Words." I'm going to copy that.

In the other pane I'm going to check my packages.json to see what we've labeled the name of the package.

Now my MPM package is building when I make changes. In one of them I'm going to run MPM run dev.
