Testing Web Components

While any test framework can work, it’s better to test web components in a browser environment because that’s where they’ll be used. Node-based frameworks would require too much shimming of DOM calls that’d make the tests unrepresentative. and are good options for browser-based testing.

is powered by ES-build, and so is the client-side of the app; let’s go down this path and see where it leads. CommonJS modules don’t work in the browser . Earlier on , using ESM on the server turned out difficult. Hopefully, that doesn’t me bite back now.

Currently using MongoDB’s free tier, which has shared RAM, and up to 5GB of storage . So far, the overall DB usage has been less than 5MB.

Query Injection

Current State of Affairs

Currently have this protection implemented back in 2018:

/**
 * @description Prevent a NoSQL Injection in the search parameters. This is
 * achieved by deleting all query values that begin with `$`.
 */
export function sanitizeQuery(query: any) {
  const keys = Object.keys(query);
  for (let i = 0; i < keys.length; i++) {
    if (/^\$/.test(query[keys[i]])) { delete query[keys[i]]; }
  }
  return query;
}
