Minor Changes

• #5086 8faf2c0 Thanks @dario-piotrowicz! - add --strict-vars option to wrangler types

  add a new --strict-vars option to wrangler types that developers can (by setting the
  flag to false) use to disable the default strict/literal types generation for their variables

  opting out of strict variables can be useful when developers change often their vars values,
  even more so when multiple environments are involved

  Example

  With a toml containing:

  [vars]
  MY_VARIABLE = "production_value"
  MY_NUMBERS = [1, 2, 3]
  
  [env.staging.vars]
  MY_VARIABLE = "staging_value"
  MY_NUMBERS = [7, 8, 9]

  the wrangler types command would generate the following interface:

  interface Env {
          MY_VARIABLE: "production_value" | "staging_value";
          MY_NUMBERS: [1,2,3] | [7,8,9];
  }
  

  while wrangler types --strict-vars=false would instead generate:

  interface Env {
          MY_VARIABLE: string;
          MY_NUMBERS: number[];
  }
  

  (allowing the developer to easily change their toml variables without the
  risk of breaking typescript types)

Patch Changes

• #7720 902e3af Thanks @vicb! - chore(wrangler): use the unenv preset from @cloudflare/unenv-preset

• #7760 19228e5 Thanks @vicb! - chore: update unenv dependency version

• #7735 e8aaa39 Thanks @penalosa! - Unwrap the error cause when available to send to Sentry

• #5086 8faf2c0 Thanks @dario-piotrowicz! - fix: widen multi-env vars types in wrangler types

  Currently, the type generated for vars is a string literal consisting of the value of the variable in the top level environment. If multiple environments
  are specified this wrongly restricts the type, since the variable could contain any of the values from each of the environments.

  For example, given a wrangler.toml containing the following:

  [vars]
  MY_VAR = "dev value"
  
  [env.production.vars]
  MY_VAR = "prod value"
  

  running wrangler types would generate:

  interface Env {
    MY_VAR: "dev value";
  }

  making typescript incorrectly assume that MY_VAR is always going to be "dev value"

  after these changes, the generated interface would instead be:

  interface Env {
    MY_VAR: "dev value" | "prod value";
  }

• #7733 dceb196 Thanks @emily-shen! - feat: pull resource names for provisioning from config if provided

  Uses database_name and bucket_name for provisioning if specified. For R2, this only happens if there is not a bucket with that name already. Also respects R2 jurisdiction if provided.
