Building Dataform core for external contributors ?

[ashish10alex]

Hi, I was trying to solve the following issue #1835. I wanted to try and change core/actions/view.ts. But I noticed that my changes have no effect when running

./scripts/run run <path_to_dataform_repo>

More specifically for testing I changed index variable in the code below to 99 to see if I am able to see the change when I run using ./scripts/run run <path_to_dataform_repo

dataform/core/actions/view.ts

Line 281 in 54dfa9c

`${this.proto.target.schema}_${this.proto.target.name}_assertions_uniqueKey_${index}`,

I assume I am missing something fundamental, e.g. I need to build the core separately ? I tried random command to wing that by running bazel build //core/... which seemed to do something but did not have an effect to the name of the assertion I was expecting. I have noticed similar behaviour when trying to change other core files such as core/session.ts. Can you please guide me to right direction ?

I have attached some screenshots below of outputs of what I have tried

1. Reproducing BUG view + assertion uniqueKey on dataform v3.0.2 #1835
   

2. An attempt at rebuilding core
