ArchUnit for JavaScript doesn't exist. What can we do about that?
Restrict dependencies between certain parts of the application. Don't use that from there.
Restrict where certain libraries can be used from. Don't use jQuery in new areas.
Restrict where certain browser APIs can be used from. Don't fetch() directly from UI components.
Restrict where certain data types can travel. Don't pass Backbone model to React component.
Prohibit cyclic dependencies.
Require a certain kind of structure in certain places. Those should all look like this.
Restrict where certain types of files can exist. Don't put that there.
Restrict which bundles certain parts of the application end up in. Don't ruin code splitting via accidental transitive imports.
Define what is allowed, what is not allowed, or both. Anything is ok except this, vs. only this is ok.
Provide an explanation as to why a restriction exists. So you remember, so someone doesn't remove it or add an ignore without understanding it (see: Chesterton's fence), to suggest alternatives when a violation occurs.
Make exceptions to the rules. For special cases, or things which have become entangled with absolutely everything, it's less repetitive to have an exception than to have lots of ignores.
Ignore a violation. There may be good reason, or it might be pre-existing.
Require justification for ignoring a violation. Documentation, encourages thinking. Distinguishes acceptable exceptions from pre-existing problems to avoid the latter being taken as precedent.
Conveniently ignore pre-existing violations when applying to an existing codebase. Start enforcing the future without first needing to finish soring out the past. There may be hundreds, or thousands.
Display violations in the editor/IDE. Like ESLint.
Use with TypeScript or Flow, which may be necessary for some features.
Use with a bundler, which may be necessary for some features.
