terser - npm Package Versions

v4.3.6

(crash hotfix)

v4.3.5

• Fixed an issue with DOS line endings strings separated by \ and a new line.
• Improved fix for the output size regression related to unused references within the extends section of a class.
• Variable names of anonymous functions (eg: const x = () => { ... } or var func = function () {...}) are now preserved when keep_fnames is true.
• Fixed performance degradation introduced for large payloads in v4.2.0

v4.3.4

• Fixed a regression where the output size was increased when unused classes were referred to in the extends clause of a class.
• Small typescript typings fixes.
• Comments with @preserve, @license, @cc_on as well as comments starting with /*! and /**! are now preserved by default.

v4.3.3

• Fixed a problem where parsing template strings would mix up octal notation and a slash followed by a zero representing a null character.
• Started accepting the name async in destructuring arguments with default value.
• Now Terser takes into account side effects inside class extends clauses.
• Added parens whenever there's a comment between a return statement and the returned value, to prevent issues with ASI.
• Stopped using raw RegExp objects, since the spec is going to continue to evolve. This ensures Terser is able to process new, unknown RegExp flags and features. This is a breaking change in the AST node AST_RegExp.

v4.3.2

• Typescript typing fix
• Ensure that functions can't be inlined, by reduce_vars, into places where they're accessing variables with the same name, but from somewhere else.

v4.3.1

• Fixed an issue from 4.3.0 where any block scope within a for loop erroneously had its parent set to the function scopee
• Fixed an issue where compressing IIFEs with argument expansions would result in some parameters becoming undefined
• addEventListener options argument's properties are now part of the DOM properties list.

v4.3.0

• Do not drop computed object keys with side effects
• Functions passed to other functions in calls are now wrapped in parentheses by default, which speeds up loading most modules
• Objects with computed properties are now less likely to be hoisted
• Speed and memory efficiency optimizations
• Fixed scoping issues with try and switch

v4.2.1

• Minor refactors
• Fixed a bug similar to #369 in collapse_vars
• Functions can no longer be inlined into a place where they're going to be compared with themselves.
• reduce_funcs option is now legacy, as using reduce_vars without reduce_funcs caused some weird corner cases. As a result, it is now implied in reduce_vars and can't be turned off without turning off reduce_vars.
• Bug which would cause a random stack overflow has now been fixed.

v4.2.0

• When the source map URL is inline, don't write it to a file.
• Fixed output parens when a lambda literal is the tag on a tagged template string.
• The mangle.properties.undeclared option was added. This enables the property mangler to mangle properties of variables which can be found in the name cache, but whose properties are not known to this Terser run.
• The v8 bug where the toString and source representations of regexes like RegExp("\\\n") includes an actual newline is now fixed.
• Now we're guaranteed to not have duplicate comments in the output
• Domprops updates

v4.1.4

• Fixed a crash when inlining a function into somewhere else when it has interdependent, non-removable variables.
