OPTIONS
  --version, -v         Prints just the compiler's version and exits.
  --help, -h            Prints this message and exits.
  --optimize, -O        Optimizes the module. Also has the usual shorthands:
​
                         -O     Uses defaults. Equivalent to -O3s
                         -O0    Equivalent to --optimizeLevel 0
                         -O1    Equivalent to --optimizeLevel 1
                         -O2    Equivalent to --optimizeLevel 2
                         -O3    Equivalent to --optimizeLevel 3
                         -Oz    Equivalent to -O but with --shrinkLevel 2
                         -O3s   Equivalent to -O3 with --shrinkLevel 1 etc.
​
  --optimizeLevel       How much to focus on optimizing code. [0-3]
  --shrinkLevel         How much to focus on shrinking code size. [0-2, s=1, z=2]
  --converge            Re-optimizes until no further improvements can be made.
  --validate, -c        Validates the module using Binaryen. Exits if invalid.
  --baseDir             Specifies the base directory of input and output files.
  --outFile, -o         Specifies the output file. File extension indicates format.
  --binaryFile, -b      Specifies the binary output file (.wasm).
  --textFile, -t        Specifies the text output file (.wat).
  --asmjsFile, -a       Specifies the asm.js output file (.js).
  --idlFile, -i         Specifies the WebIDL output file (.webidl).
  --tsdFile, -d         Specifies the TypeScript definition output file (.d.ts).
  --sourceMap           Enables source map generation. Optionally takes the URL
                        used to reference the source map from the binary file.
  --runtime             Specifies the runtime variant to include in the program.
​
                         full  Default runtime based on TLSF and reference counting.
                         half  Same as 'full', but not exported to the host.
                         stub  Minimal stub implementation without free/GC support.
                         none  Same as 'stub', but not exported to the host.
​
  --noUnsafe            Disallows the use of unsafe features in user code.
                        Does not affect library files and external modules.
  --debug               Enables debug information in emitted binaries.
  --noAssert            Replaces assertions with just their value without trapping.
  --noEmit              Performs compilation as usual but does not emit code.
  --importMemory        Imports the memory provided as 'env.memory'.
  --sharedMemory        Declare memory as shared by settings the max shared memory.
  --memoryBase          Sets the start offset of compiler-generated static memory.
  --importTable         Imports the function table provided as 'env.table'.
  --exportTable         Exports the function table as 'table'.
  --explicitStart       Exports an explicit start function to be called manually.
  --lib                 Adds one or multiple paths to custom library components and
                        uses exports of all top-level files at this path as globals.
  --path                Adds one or multiple paths to package resolution, similar
                        to node_modules. Prefers an 'ascMain' entry in a package's
                        package.json and falls back to an inner 'assembly/' folder.
  --use, -u             Aliases a global object under another name, e.g., to switch
                        the default 'Math' implementation used: --use Math=JSMath
  --trapMode            Sets the trap mode to use.
​
                         allow  Allow trapping operations. This is the default.
                         clamp  Replace trapping operations with clamping semantics.
                         js     Replace trapping operations with JS semantics.
​
  --runPasses           Specifies additional Binaryen passes to run after other
                        optimizations, if any. See: Binaryen/src/passes/pass.cpp
  --enable              Enables WebAssembly features that are disabled by default.
​
                         sign-extension      Sign-extension operations
                         bulk-memory         Bulk memory operations.
                         simd                SIMD types and operations.
                         threads             Threading and atomic operations.
                         reference-types     Reference types and operations.
​
  --disable             Disables WebAssembly features that are enabled by default.
​
                         mutable-globals     Mutable global imports and exports.
​

  --traceResolution     Enables tracing of package resolution.
  --listFiles           Lists files to be compiled and exits.
  --measure             Prints measuring information on I/O and compile times.
  --printrtti           Prints the module's runtime type information to stderr.
  --noColors            Disables terminal colors.
  -- ...                Specifies node.js options (CLI only). See: node --help
