Build Guide

Environment Requirements

• Go 1.22.0 and later
• Node.JS v18.0.0 and later

Build on Unix / Linux / macOS by following Makefile:

DIST = ./dist
SRC = ./src
WASM = ${DIST}/excelize.wasm

make: install test build
install:
    npm install
test:
    cd cmd && GOOS=js GOARCH=wasm go test -v \
        -exec="${GOROOT}/misc/wasm/go_js_wasm_exec" \
        -coverprofile=c.out ./ && go tool cover -html=c.out
build:
    rm -rf ${DIST} && mkdir ${DIST}
    node ./node_modules/.bin/rollup -c
    cd cmd && GOOS=js GOARCH=wasm CGO_ENABLED=0 \
        go build -v -a -ldflags="-w -s" \
        -gcflags=-trimpath=${GOPATH} \
        -asmflags=-trimpath=${GOPATH} \
        -o ../dist/excelize.wasm ./main.go
    gzip -f --best ${WASM}
    cd ..
    cp LICENSE ${DIST}
    cp README.md ${DIST}
    cp package.json ${DIST}
    cp ${SRC}/index.d.ts ${DIST}

Build on Windows by following Powershell build.ps1:

• Gzip for Windows

$DIST = ".\dist"
$SRC = ".\src"
$WASM = "$DIST\excelize.wasm"
$GOPATH = go env GOPATH

npm install
if (Test-Path $DIST) {
    Remove-Item -Recurse -Force $DIST
}
mkdir $DIST
.\node_modules\.bin\rollup -c
cd cmd
$env:GOOS="js"; $env:GOARCH="wasm"; $env:CGO_ENABLED=0; `
    go build -v -a -ldflags="-w -s" `
    -gcflags=-trimpath=$GOPATH `
    -asmflags=-trimpath=$GOPATH `
    -o ..\dist\excelize.wasm .\main.go
cd ..
gzip -f --best $WASM
Copy-Item LICENSE $DIST
Copy-Item README.md $DIST
Copy-Item package.json $DIST
Copy-Item $SRC\index.d.ts $DIST 

Execute powershell script by the following command:

powershell -File build.ps1
